The research building of Nihon University College of Engineering was 36 years old in 2001, and "red water" caused by rust corrosion in the pipes was occurring. The verification of the rust prevention effect of the NMR Pipe Protector is usually conducted by the relevant parties at the installation site, who collect water samples and send them to a public testing agency for water quality testing. However, in the exceptional case of its introduction to Nihon University College of Engineering, the university expressed a desire to conduct its own verification of effectiveness since it could perform water quality testing on-site. Therefore, Professor Hirayama from the Department of Materials Science and Engineering conducted the water quality tests. ◆ Results of Nihon University College of Engineering's own rust prevention effect verification Before the installation of the NMR Pipe Protector, the iron concentration in the water of Building 8 was found to be 7.80 mg/l, indicating significant rust corrosion. In tests conducted four weeks after installation, the iron concentration dropped to 0.11 mg/l, confirming a substantial reduction. By six weeks after installation, the concentration further decreased to 0.03 mg/l. Water quality tests were also conducted in Buildings 9 and 10, which were affected by the treatment, and it was confirmed that the iron concentration in all buildings had decreased to nearly the same level as that of Building 8. The university's Secretary General, Mr. Takamatsu, expressed great surprise at the rapid confirmation of the rust prevention effect and praised the high effectiveness of the NMR Pipe Protector.

The famous bookstore in Shinjuku, as of 2005, had been in operation for 41 years and required measures to address aging plumbing. However, it was discovered that asbestos had been used in the ceiling of the building, making plumbing renovation work difficult. The reason for this was that due to the risk of asbestos dispersion, restrictions on its use in surrounding buildings were necessary. In addition to the 3 to 6 months or more of facility closure required for plumbing renovation, a separate closure period for asbestos removal work was also needed. The cost of asbestos treatment was 2 to 3 times that of plumbing renovation. This issue can be completely resolved with the NMR Pipe Protector. The installation of the NMR Pipe Protector does not require asbestos removal, there is no water outage, and the work is completed in 1 to 2 hours. The introduction cost is 5 to 10% of the plumbing renovation cost, and since there is no need for asbestos removal expenses, significant cost savings are possible. Therefore, the major equipment company that became the general contractor for the plumbing deterioration measures for this project considered the NMR Pipe Protector to be the optimal solution and decided to implement it. The NMR Pipe Protector was installed in 2005, and as of 2020, the building is now 56 years old. The air conditioning chilled and hot water pipes that have been in use since the completion of the building have significantly exceeded their expected lifespan, yet they are being used without any progression of red rust corrosion.

According to the U.S. manufacturing technology magazine "Manufacturing Technology Insights," on March 12, 2020, the NMR Pipe Protector, a device for preventing red rust in piping, was selected as one of the top 10 rust prevention technologies in the world for its ability to prevent red rust corrosion. The magazine is noted for providing information on technology solutions that impact the manufacturing sector. ◆ The innovative rust prevention method of the NMR Pipe Protector - NMRPT The rust prevention method of the NMR Pipe Protector reduces red rust in piping, which causes various problems, to beneficial black rust, thereby preventing red rust corrosion and strengthening the piping. This rust prevention method is a unique technology that is not found elsewhere. ◆ Achievements of the NMR Pipe Protector - NMRPT - adopted in important facilities The NMR Pipe Protector has been recognized for its excellent rust prevention effects and has been implemented in over 4,200 buildings to date. It has been widely adopted in globally renowned buildings such as Buckingham Palace, the London City Hall (Guildhall), and Windsor Castle. Not only is its rust prevention effect highly regarded, but the trust in the product has also been acknowledged, leading to its selection as one of the top 10 rust prevention technologies in the world by "Manufacturing Technology Insights."

Over the past 30 years, magnetic devices claiming to prevent rust in piping have been sold by more than 150 companies. However, there is not a single product whose rust prevention effect has been scientifically proven. Currently, methods considered for rust prevention in piping, such as sacrificial anode cathodic protection and electrode methods, are only capable of providing partial rust prevention effects and cannot be expected to work on the entire piping system. The resins used in epoxy lining methods for water supply pipes contain bisphenols, which have raised concerns about their harmful effects on human health in the United States and Canada. Additionally, the application to elbow sections is uneven, leading to the reoccurrence of red rust, necessitating future piping replacement. The NMR Pipe Protector, a device for preventing red rust in piping, transforms red rust into black rust through reduction, thereby providing rust prevention and extending the lifespan of the piping. Unlike red rust, which is soluble in water, black rust becomes an insoluble, hard crystalline passivation, and the black rust coating formed by this transformation prevents the occurrence of new red rust. The volume of black rust is less than one-tenth that of red rust, and the transformation to black rust reduces blockages within the piping. This rust prevention principle has been presented in research papers by organizations such as the Japan Corrosion Control Association and the Asia-Pacific Corrosion Association.

Due to aging, the piping system experiences red rust corrosion. In vinyl-lined steel pipes, the straight sections do not rust, but at the joints, the iron parts come into contact with water, making red rust deterioration unavoidable. Even if over 90% of the joint sections are blocked by red rust, the discoloration of water due to red rust, known as "red water," does not occur. Therefore, it is common not to notice the progression of red rust corrosion within the piping. Even if the red rust deterioration is only at the joints, it is necessary to replace the entire piping system, so caution is required. The typical lifespan of water supply piping is considered to be 20 to 30 years, and if it exceeds this lifespan, the risk of leaks and other issues significantly increases. When implementing piping renewal work as a countermeasure, it involves long-term water outages and substantial construction costs, which can be a heavy burden. In the case of apartment water supply piping, the introduction cost of the NMR Pipe Protector is about one-fifth to one-tenth of the renewal construction costs, allowing for significant cost reductions. The NMR Pipe Protector is designed to extend the long-term lifespan of the piping, and as long as water is being used, it can prolong the piping lifespan until the building's lifespan ends. The NMR Pipe Protector is the only device that enables rust prevention by converting red rust inside the piping into black rust.

In 2007, at the Legend Hotel Saigon in Vietnam, due to the water quality issues that facilitate red rust corrosion, significant red rust corrosion had progressed within six years of construction. This resulted in serious red water issues in all guest rooms, making it impossible for guests to even take a shower. Taisei Corporation, responsible for the construction, found that responding to the hotel's request for pipe replacement would require enormous costs and compensation for the hotel's closure, making it unfeasible. Since they had already understood the rust prevention effects of the NMR Pipe Protector from another project, its adoption was decided. Installation from outside the pipes meant there was no water outage, allowing the hotel to continue operations without the need for closure compensation. In 2008, the NMR Pipe Protector was installed, and about a month and a half later, water quality tests were conducted in ten guest rooms that had experienced severe red water issues. The results showed that red rust had been eliminated in all rooms, improving the water to a clear state. Thus, the adoption of the NMR Pipe Protector by a major general contractor in this complaint handling case can be seen as a testament to their high evaluation of its rust prevention effectiveness.

The "Palace Tsurumi," a condominium built in 1972 in Yokohama City, Kanagawa Prefecture, had been in existence for 39 years without any maintenance on the water supply pipes since its completion, raising concerns about red rust corrosion within the piping. The management association, which had debts from exterior wall repair work, did not have the funds necessary for pipe renewal and was looking for alternative solutions when Chairman Kanaya discovered the NMR Pipe Protector, a device that could be implemented at about one-fifth to one-tenth the cost of pipe renewal. Upon inquiring further about the details, it was found to have a warranty system for effectiveness, allowing for its safe introduction in 2011. ◆ Results of NMR Pipe Protector - NMRPT - Installation at Palace Tsurumi After the installation of the NMR Pipe Protector, an investigation using an endoscope was conducted to confirm the anti-corrosion effect. The investigation, conducted seven years after the installation, showed a reduction in red rust blockage rates of 35.3% and 17.4% in the water supply pipes of the two surveyed rooms, confirming the anti-corrosion effect. The Palace Tsurumi, which had not undergone any maintenance on its piping for 39 years since its completion, has now been in existence for 48 years, and it has been proven that no issues due to red rust corrosion have occurred, demonstrating the sustained longevity of the piping.

The 29-year-old condominium, Cosmo Kajigaya Le Seine, located in Kawasaki City, Kanagawa Prefecture, was planning lining work to address the deterioration of the water supply pipes due to red rust. However, as the repair reserve fund was depleted, they adopted the NMR Pipe Protector in 2002, which can prevent the deterioration of red rust in pipes at a low cost. ◆Key Factors for Adopting NMR Pipe Protector The decision to introduce the NMR Pipe Protector was made with peace of mind due to the one-year money-back guarantee in case of no effectiveness, along with an internal inspection of the pipes using an endoscope to verify the rust prevention effect after installation. ◆Success in Preventing Red Rust and Reducing Costs On the tenth anniversary of the NMR Pipe Protector installation, when the water supply pipe in the exclusive area was cut in half on-site for inspection, Mr. Itaya, the chair of the building committee of the condominium, stated, "The residents were surprised to find no red rust inside the pipes." By changing the long-term repair plan from lining work to the NMR Pipe Protector, they were able to free up funds, and the installation of an elevator also increased the asset value of the condominium, according to Mr. Itaya. The NMR Pipe Protector does not require running costs and provides rust prevention for over 40 years, resulting in significant cost reductions in the long term.

Currently, issues regarding the aging of water pipes and the costs of their repairs are arising among building managers and water infrastructure, and the "NMR Pipe Protector," a rust prevention device developed by Japan System Planning Co., Ltd., is gaining attention. The reason is that the NMR Pipe Protector can be introduced at a cost of less than 1/5 to 1/10 compared to pipe replacement, without the need for large-scale construction or water outages, thus solving the disadvantages of pipe replacement work. In the business program "Kigyo Tamashii" on TOKYO MX, "Hotel Serve Shibuya" and "Social Welfare Corporation Jonankai Care House Shirasagi" were featured as users of the NMR Pipe Protector. The rust prevention effect inside the pipes after the installation of the NMR Pipe Protector has been reported to be good, and in interviews with local staff, the NMR Pipe Protector was highly praised, receiving words of joy. The representative director, Kumano, believes that the budget shortage issue in maintaining water infrastructure can be resolved by the NMR Pipe Protector and stated the necessity of market development for water services in the program. He also emphasized the importance of Japan System Planning contributing to society to maintain current water rates. ▼Broadcast content can be found here https://youtu.be/qNCf_ru0E14

The effects of the introduction of the NMR Pipe Protector at the Royal Bank of Scotland became apparent immediately. A re-examination of the iron content in the hot water, which was 1.10 mg/l before installation, showed that after nine weeks, the hot water was clear, and the amount of dissolved iron had decreased to about one-third, at 0.41 mg/l. The investigation continued for a year, and the iron content in the same hot water ultimately decreased to about one-thirtieth of the pre-installation level, at 0.03 mg/l. The progression of red rust within the pipes also stopped, and the red rust transformed from the surface to black rust. It can be said that the NMR Pipe Protector fundamentally solved the red rust problem without the need to replace the piping. The fact that an innovative and influential company like the Royal Bank of Scotland adopted the NMR Pipe Protector is very significant. The environmentally conscious management policy has shown even greater movement as of April 2020 and is being applied to investment targets as well. The benefits of cost reduction, along with proactive efforts to address global environmental destruction issues without updating energy-consuming piping, will serve as a good stimulus for other companies. Not only in the UK but also in Japan, the number of buildings, such as apartments and hospitals, that are introducing the NMR Pipe Protector is increasing year by year.

◆Rust Prevention Results of NMR Pipe Protector at the London City Hall Before the installation of the NMR Pipe Protector, red water was coming from the hot water pipes at Guildhall, London, every morning when use began. Water quality testing showed an iron content of 6.36 mg/l, which is significantly higher than the UK water quality standard of 0.2 mg/l, indicating severe rusting. After installing the NMR Pipe Protector and measuring the iron content three weeks later, it was reduced to 0.015 mg/l. Furthermore, after measuring seven weeks post-installation, it decreased to 0.007 mg/l, indicating that the red rust had transformed into black rust, which does not dissolve in water. The red water issue was resolved, and the installation of the NMR Pipe Protector eliminated the red rust problem in the hot water pipes at Guildhall, London. As a result, a letter of recommendation was issued in the names of the Head of the Real Estate Management Division of the London City Hall Investigation Project Department and the Head of the Technical Services Division of the London City Hall. The installation of the NMR Pipe Protector in the hot water supply pipes of the west wing of the London City Hall noted: • A 99% reduction in red rust compared to before installation • Confirmation of rust prevention effects within four weeks post-installation • Complete disappearance of the previously constant red water and improvement in water quality These points confirm and recommend the rust prevention effectiveness of the NMR Pipe Protector.

At Kumamoto Red Cross Hospital, the introduction of the NMR Pipe Protector has resolved the issue of red rust. To explain how the NMR Pipe Protector removes red rust, it converts red rust into black rust. Unlike red rust, black rust does not dissolve in water and has a volume that is one-tenth of that of red rust. Therefore, it can also solve the blockages caused by red rust. In 2014, as a measure to prevent the deterioration of piping, the NMR Pipe Protector was introduced in some systems at Kumamoto Red Cross Hospital, and due to the recognized anti-corrosion effects, it was implemented throughout the entire facility in 2016. In a water quality survey conducted before the introduction of the NMR Pipe Protector, the iron content in the hospital's air conditioning hot water was high at 12.3 mg per liter due to red rust dissolving in the water. However, after converting the surface of the red rust to black rust, it was reduced to just 0.07 mg in only two weeks, achieving a concentration reduction of approximately 82%. Kumamoto Red Cross Hospital's section chief, Ogawa, also stated in the Air Conditioning Times of 2018, "We noticed the clarity within a few weeks after the introduction," clearly demonstrating the effectiveness of the NMR Pipe Protector. By deciding to implement the NMR Pipe Protector, Kumamoto Red Cross Hospital has not only been able to protect the medical environment from leaks caused by red rust but has also been able to allocate more budget to other areas.

◆Results of Introducing NMR Pipe Protectors In January 2007, NMR Pipe Protectors were installed at Buckingham Palace. At that time, Buckingham Palace was using galvanized steel pipes for the air conditioning hot water and hot water supply systems, and the circulating hot water for Queen Elizabeth's room had turned reddish-brown due to rust. The purpose of introducing the NMR Pipe Protectors was to make this water clear and to extend the life of the pipes. Before installation, the iron content in the air conditioning hot water pipes was very high at 16.6 mg/l, and there was a large amount of red rust present in the pipes. After the installation of the NMR Pipe Protectors, a water quality test conducted 24 days later showed that the iron content had decreased to 0.46 mg/l, clearing the standard value of 1.0 mg/l, and the water color had also changed to clear. In the hot water supply pipes, the iron content was 2.8 mg/l before installation, but 24 days after the installation of the NMR Pipe Protectors, it dropped to 0.018 mg/l, significantly clearing the water quality standard of 0.2 mg/l, and the water color also became clear, demonstrating the high rust prevention effectiveness of the NMR Pipe Protectors. Currently, Buckingham Palace is undergoing pipe renovation work, but due to security reasons, construction personnel are generally prohibited from entering the area around Her Majesty's room, making renovations impossible. However, the NMR Pipe Protectors have resolved this issue.

The British Museum introduced the NMR Pipe Protector, a device to prevent red rust deterioration in pipes, to protect cultural properties from water leaks caused by red rust deterioration in the piping system in March 2016. ◆ NMR Pipe Protector for Preventing Red Rust in Pipes Before installation at the British Museum, the iron content in the water was 20.0 mg/l, raising concerns about leaks due to red rust deterioration in the pipes. However, five weeks after installation, this value decreased to 0.2 mg/l, a reduction of 1/100, completely halting the progression of red rust. The rust prevention effect of the NMR Pipe Protector was evaluated, leading to an additional installation in a separate piping system at the British Museum in March 2018. ◆ Rust Prevention Effect of the NMR Pipe Protector Water supply and air conditioning pipes can experience red rust deterioration, leading to blockages, red water, and leaks. When the NMR Pipe Protector is attached to the piping, it transforms red rust into black rust through the action of electromagnetic waves. Black rust forms a hard crystal that does not dissolve in water, creating a coating inside the pipes that prevents the occurrence of red rust and leaks. Since the volume of black rust is 1/10 that of red rust, the blockage caused by red rust in the pipes is reduced. As a result, the NMR Pipe Protector has eliminated the risk of leaks at the British Museum and has played a role in protecting cultural properties. Additionally, the NMR Pipe Protector has been implemented in over 4,200 buildings, so please feel free to inquire for more information.

The "Teigeki Building" in Marunouchi, Chiyoda Ward, Tokyo (54 years old as of 2020) had galvanized steel pipes used for air conditioning chilled and hot water piping that experienced some leakage due to red rust 20 years ago in Heisei 12, when the building was 34 years old. To prevent red rust deterioration, NMR pipe protectors were installed. Since then, there have been no new leaks, and as of 2020, despite being 54 years old, there are no issues with red rust, and the air conditioning chilled and hot water piping no longer needs to be updated. Currently, there are still no problems with red rust deterioration, and the system is in use. The results of the introduction of the NMR pipe protector in the Teigeki Building were featured in an article in the air conditioning and refrigeration industry magazine "Kuchou Times" in the January 1, 2019 issue.

~Solving the problem of old building water piping around the world suffering from red rust deterioration~ The red rust prevention device for piping, "NMR Pipe Protector," has obtained and registered patents in Japan, the United States, South Korea, and Hong Kong. Until recently, the Japanese patent system only respected the first-to-file principle, meaning that if someone documented their idea or technology and filed a patent application first, they could obtain the patent. Recently, however, the content of patents has been more rigorously examined to determine whether it is "feasible" and whether the patent content is truly "correct," assessing whether a product can actually be developed from the patent or if it genuinely functions. Only those that pass this scrutiny are registered as patents. In particular, U.S. patents undergo strict examination, and if the patent content is not recognized as an actual product or device, it will not be granted. For example, during the examination of U.S. patents, it is questioned and assessed whether the patented technology is truly "commercially viable." The red rust prevention device for piping, "NMR Pipe Protector," has successfully passed such stringent patent examinations abroad and has been granted and registered patents in major countries around the world.

On November 23, 2006, three NMR pipe protectors were installed in all iron circulation hot water and air conditioning piping systems at the Royal Garden Hotel. Before the installation of the NMR pipe protectors, the iron content in the hot water was very high at 2.79 mg/l, indicating significant red rust deterioration. After 25 days of installing the NMR pipe protectors, the iron content in the hot water dropped to 0.016 mg/l, a reduction of nearly 95% compared to before installation, and well below the drinking water standard of 0.2 mg/l, demonstrating the rust prevention effect of the NMR pipe protectors. This indicates that the NMR pipe protectors successfully prevented the occurrence of new red rust and transformed it into black rust. Additionally, leaks that had occasionally occurred prior to the installation of the NMR pipe protectors have not happened at all in the past 14 years since their installation. Thus, by introducing the NMR pipe protectors, the piping at the Royal Garden Hotel has become usable for as long as the building continues to be in use. The hotel management is very satisfied with the results of the NMR pipe protector installation, and the Royal Garden Hotel is considering the additional installation of NMR pipe protectors for the air conditioning chilled water piping in the future.

The first hospital to verify the "NMR Pipe Protector" - NMRPT - was the "Former Medical Center of the Japanese Red Cross Society." In 1999, the water supply pipes of the former medical center, which had been built 24 years earlier, were made of galvanized steel. Red rust had developed inside the water supply pipes, and the water from the tap in the newborn room showed an iron ion concentration of 2.0 mg/l in the morning, significantly exceeding the water quality standard of 0.3 mg/l. As a result, large amounts of water were run before use. To prevent future leaks, one NMR Pipe Protector was installed on the secondary side piping of the elevated water tank. Water was sampled from the tap in the newborn room, located about 150 meters from the elevated water tank, to verify the effectiveness of rust prevention. Measurements of the iron ion concentration in the water at the Tokyo Metropolitan Institute of Public Health showed that before the installation of the NMR Pipe Protector, the level was 2.0 mg/l, but it dropped to 0.48 mg/l two weeks after installation and to 0.27 mg/l six weeks after installation, proving that the NMR Pipe Protector prevented new red rust in the water supply pipes and reduced existing red rust to non-soluble black rust. Because these verification results were beneficial for other Red Cross hospitals, they were introduced in the January 2000 issue of the internal newsletter of the Japanese Red Cross Medical Center to hospitals nationwide.

At Whittington Hospital, the iron concentration of the hot water that had been sitting overnight before the installation of the NMR Pipe Protector was 7.3 mg/l. Since the UK water quality standard is 0.2 mg/l, this indicates that the iron level was more than 36 times the standard, showing significant corrosion from red rust in the pipes. Nineteen days after the installation of the NMR Pipe Protector, the iron concentration in the water decreased to 0.4 mg/l, and by twenty-nine days after installation, it further decreased to 0.08 mg/l. This result demonstrated that the occurrence of red rust was completely prevented and that the red rust in the pipes had transformed into black rust. ◆ The NMR Pipe Protector allows pipes to be used for the lifespan of the building Whittington Hospital introduced the NMR Pipe Protector to prevent the deterioration of red rust in the hot water pipes and extend their lifespan by over 40 years. The cost of introducing the NMR Pipe Protector is approximately 1/10 to 1/5 of that of pipe replacement, allowing for an expected cost reduction of 80 to 90%. Pipe replacement requires water shut-off work, but the introduction of the NMR Pipe Protector does not require any water shut-off. From the case of Whittington Hospital, I hope you have understood the performance of the NMR Pipe Protector. If you wish to continue using safe and secure water indefinitely, please consider the introduction of the NMR Pipe Protector!

It is possible to remove red rust inside pipes through pipe cleaning and sandblasting; however, these methods put a strain on the pipes due to water pressure and abrasion, which can reduce their strength. The NMR Pipe Protector is a device that is installed on the outside of the pipes, allowing it to solve the red rust problem without putting any strain on the pipes. Generally, the lifespan of pipes is less than half that of the building, and maintaining their condition requires attention. However, since the inside of the pipes is not usually visible, red rust deterioration can progress unnoticed, often leading to issues such as red water or leaks by the time one becomes aware of it. For addressing red rust deterioration inside pipes, there are options such as pipe replacement and several rehabilitation methods, but improvements to red rust are temporary, necessitating further measures over time. The NMR Pipe Protector is designed not only for its rust prevention effects but also to extend the lifespan of pipes until the building's lifespan ends, making its introduction optimal for long-term pipe longevity. The NMR Pipe Protector reduces red rust inside pipes to black rust. Black rust does not dissolve in water and forms a hard crystalline passive layer, which has a volume less than one-tenth that of red rust, thereby improving red rust blockage. This is a unique technology of the NMR Pipe Protector.

In the "Cosmo Kajigaya Le Seine" condominium located in Takatsu Ward, Kawasaki City, Kanagawa Prefecture, the NMR Pipe Protector was introduced 18 years ago in 2002, from the present year of 2020. At the time of considering the introduction of the NMR Pipe Protector, Mr. Toshimasa Itaya, the chairman of the construction committee for the "Cosmo Kajigaya Le Seine" management association, learned about the NMR Pipe Protector through academic journals related to construction and air conditioning, as well as advertisements in trains. The "one-year effectiveness guarantee" and "subsequent follow-up surveys" were decisive factors in the decision to adopt the NMR Pipe Protector. Compared to the lining work that was scheduled in the long-term repair plan when the condominium reached its 20th anniversary, the NMR Pipe Protector significantly extended the lifespan of the water supply pipes to over 40 years. As a result, the expenses in the long-term repair plan were reduced by 80%, creating financial flexibility. Consequently, during the extraordinary general meeting, proposals for the installation of the NMR Pipe Protector and the new elevator were presented together and approved. The long-desired installation of the elevator, which was highly requested by residents, became possible, increasing the added value of the condominium and having a significant impact on the enhancement of its asset value, as Chairman Itaya stated.

The "Cosmo Kajigaya Le Seine" conducted a pipe inspection of the exclusive technical management area in 2001, the year before the installation of the NMR pipe protector, and found red rust corrosion, which necessitated urgent measures in the near future. Therefore, in 2002, the 15th year of its construction, the NMR pipe protector was installed, and since then, no problems due to pipe deterioration have occurred. A pipe inspection of the exclusive water supply section was conducted 10 years after installation, in 2012. The interior of the pipes was found to be in a clean state with no progression of red rust, and some black rust was also confirmed, verifying the rust prevention effect of the NMR pipe protector. The removed pipes were displayed on-site, and residents were reportedly surprised by the clean condition inside the pipes. Mr. Itaya, a member of the management committee's architectural expert group, shared the following thoughts on the introduction of the NMR pipe protector: "Thanks to the encounter with the NMR pipe protector, we were able to finally install the long-desired elevator. Furthermore, the added value of the condominium has increased, significantly impacting the asset value." Chairman Nagamura mentioned, "In the future, we want to aim for a more comfortable living environment for residents while reviewing the long-term repair plan."

~Mansion Management Newspaper, March 25, 2017, Excerpt~ "Confirmation of black rust progression through pipe inspection" "Confident that the current condition can be maintained until the building's lifespan" The "Co-op Nomura Minami Ishikiri" in Wakabayashi Ward, Sendai City, Miyagi Prefecture (built in 1978, three stories, 24 units) has had the NMR Pipe Protector installed for 15 years. We interviewed them about the present situation. The installation of the NMR Pipe Protector at "Co-op Nomura Minami Ishikiri" took place in August 2001, the year it reached its 24th anniversary. Fifteen years have passed since then, and this year it celebrates its 39th anniversary. "Not only the water supply pipes but also the drainage pipes have been extended in lifespan, and there are no plans for updates in the long-term repair plan," says Takeshi Furuta, the board member in charge of maintenance. Four years ago, they commissioned experts to create a long-term repair plan for the next 30 years. This plan includes a budget for replacing the NMR Pipe Protector when the building reaches 63 years old. According to the manufacturer, Nippon System Planning, the effectiveness lasts for 40 years after installation, but it gradually declines thereafter. Therefore, there is a plan to replace it with a new device in the 41st year of installation. The 41st year corresponds to the building being 63 years old. "In other words, we aim to maintain the current condition until the building's lifespan," says Director Furuta.

In "Co-op Nomura Minami Ishikiri," located in Wakabayashi Ward, Sendai City, Miyagi Prefecture, which was built 43 years ago as of 2020, an NMR pipe protector was introduced in August 2001, 19 years ago. After 15 years of use, a deterioration diagnosis survey of the water supply pipes was conducted when the building was 39 years old. The investigation involved removing the water supply pipes from the secondary side of the elevated water tank and inside the residences. The report evaluated that "the progression of deterioration due to red rust inside the pipes has completely stopped, there is no blockage, the surface has turned black due to rust, and it has been confirmed that the pipes have been rehabilitated." Additionally, the dirt in the drainage pipes has decreased, allowing for a 30% reduction in the frequency of drainage pipe cleaning, which had previously been conducted once a year. Takemori Furuta, the maintenance officer of the condominium, stated, "Not only the water supply pipes but also the drainage pipes have been extended in their lifespan, and there is no longer a need for updates in the long-term repair plan," and added, "As the years go by, it will only become more financially challenging, so the benefit of not having to update the water supply pipes is extremely significant." An article on this topic has been published in the condominium management newspaper, and an excerpt will be introduced next time.

◆What is Buckingham Palace, where the NMR Pipe Protector has been introduced? The place where Prince William and Princess Catherine appeared on the balcony to greet the public on their wedding day is Buckingham Palace. It is a representative building of the UK and currently serves as the residence of Queen Elizabeth. Buckingham Palace began in 1703 when the Duke of Buckingham built it, and it became associated with the royal family when George III inherited the residence in 1761. His son, George IV, commissioned architect John Nash to rebuild the old tower, construct the triumphal arch (now known as Marble Arch) to commemorate victory over Napoleon, and create the center room adorned with jewels, transforming it from Renaissance style to Neo-Classical style. Later, Queen Victoria moved to Buckingham Palace upon her accession, and it became the official royal residence in 1837. The estate covers an area of 10,000 tsubo, has 775 rooms, and employs around 800 staff members day and night. This concludes our introduction to Buckingham Palace, where the NMR Pipe Protector has been introduced. Next time, we will discuss the background of the introduction of the NMR Pipe Protector at Buckingham Palace!

◆Background of the Introduction of NMR Pipe Protectors at Buckingham Palace In addition to the Queen's private rooms, the palace includes offices, meeting rooms, the administrative headquarters of the royal household, a museum, and a ballroom, serving as a venue for official duties and accommodations for foreign leaders. Therefore, the presence of red water from the British royal palace's bathrooms and toilets is certainly not something that reflects well on the monarchy. The impetus for Buckingham Palace to introduce NMR pipe protectors came from Harrods, a long-established department store that is a royal warrant holder. In March 2006, NMR pipe protectors were urgently introduced as a countermeasure against red water, and within 1.5 months, the occurrence of red water was completely halted. Following this result, Harrods' executives introduced NMR pipe protectors to Windsor Castle, which was also facing issues with red rust. In November 2006, NMR pipe protectors were installed in the Queen's Tower, where Her Majesty the Queen stayed every weekend, and the reddish-brown water transformed into clear water after 42 days, concluding the verification. As a result of this, NMR pipe protectors were introduced at Buckingham Palace, which was also experiencing red rust issues. Next time, I will discuss the results of the introduced NMR pipe protectors!

Guildhall London is a UNESCO World Heritage site, where the NMR pipe protector has been installed. Guildhall London serves as the city hall of London and is an important facility with a long history and architectural significance. It consists of several buildings, which together have been registered as a World Heritage site. One of these is the Great Hall. The Great Hall is a historic building that received the highest accolades at the time of its construction in the 14th century. It is characterized by its Gothic architecture and can be appreciated as a kind of artwork. Additionally, when visiting Guildhall London, the art gallery is highly recommended. As the name suggests, it is a building that displays numerous works of art, with some pieces dating back to the 17th century. Although the gallery is not very large, it showcases around 250 works at any given time, providing ample enjoyment. Next time, I will talk about the NMR pipe protector introduced in this important historical building, Guildhall London!

What is the NMR Pipe Protector that is also being implemented at the Guildhall in London? The NMR Pipe Protector is a rust prevention device for piping that has been on the market for over 25 years. It has been installed in many important buildings, with over 4,200 buildings equipped as of 2020. The NMR Pipe Protector has the effect of reducing red rust to black rust, and while both are types of rust, black rust has properties that strengthen the piping, making it beneficial for the pipes. As a result, the piping can continue to be used without replacement until the building's lifespan ends. Black rust has been utilized for a long time, being used in southern iron kettles and in nails and hinges of shrines and temples. Additionally, there is no concern that black rust will dissolve in water like red rust. The NMR Pipe Protector also works to prevent the growth of bacteria that cause water stains and slime. In regular pipe cleaning, bacteria will reappear after 2 to 3 years, but with the installation of the NMR Pipe Protector, this will no longer be necessary. The installation is also simple and can be done without cutting off the water supply, which is another recommended point. Next time, I will talk about the results achieved by the NMR Pipe Protector when it was implemented at the London City Hall!

At Kumamoto Prefectural's largest hospital, "Kumamoto Red Cross Hospital," the "NMR Pipe Protector" - NMRPT - is making a significant impact. The Kumamoto Red Cross Hospital, which introduced the NMR Pipe Protector, is a historic hospital established in 1944. Operated by the Kumamoto branch of the Japanese Red Cross Society, it boasts the largest area among hospitals in Kumamoto Prefecture, currently offering 30 medical departments and 490 beds. Designated as a disaster base hospital for Kumamoto Prefecture, it plays a crucial role in supporting healthcare in the region by providing high-quality cancer treatment and medical care for mothers and children before and after childbirth. The fundamental philosophy of Kumamoto Red Cross Hospital is to be close to people and society through medical care and relief, based on the spirit of the Red Cross, which encompasses three core elements: "humanity, impartiality, and service." This philosophy serves as a guiding principle for patient care, emphasizing respect for patients' personalities, ethical views, and perspectives on life and death, as well as a strong commitment to building trust. In the next installment, we will explain the aging issue of the water pipes at Kumamoto Red Cross Hospital, which led to the decision to introduce the NMR Pipe Protector. Please stay tuned.

◆Concerns about Red Rust Deterioration in Pipes at Kumamoto Red Cross Hospital and Countermeasures If the pipes are deteriorating, problems such as red water and leaks may occur. The cause of this is red rust inside the pipes. Red rust is characterized by its rapid progression and its tendency to dissolve easily in water. The issue with red water is that it is difficult to notice its presence at an early stage. When thinking of red water, one might imagine water stained red, but in reality, even if red rust mixes with tap water, it does not easily change color. Another problem is "leakage." As red rust gradually flows into the water, it erodes the threaded parts and walls inside the pipes, leading to leaks when it reaches the outside. In medical facilities, leaks can lead to malfunctions of medical equipment and are also undesirable from a hygiene perspective. The occurrence of red rust also poses the risk of "red rust blockage," which can lead to poor water flow. Therefore, maintenance of water pipes has always been a concern at Kumamoto Red Cross Hospital. The NMR Pipe Protector addresses such issues. In the next installment, which will be the final one, we will introduce how Kumamoto Red Cross Hospital resolved these problems through the introduction of the NMR Pipe Protector.
