On the front page of the morning edition of the Yomiuri Shimbun on July 26, 2025 (Saturday), an advertisement for our product "NMR Pipe Protector" was published. The advertisement specifically introduces how the NMR Pipe Protector can contribute to addressing the issues of red rust and renewal costs of piping in aging buildings and old facilities through concrete examples. - Significantly reduces piping renewal costs (to about one-tenth or less) - Confirmed over 15 years of extension effect through X-ray diagnosis in a 50-year-old condominium - Reduces the risk of equipment renewal in aging buildings such as hospitals and hotels Through these achievements, we suppress the occurrence of red rust and realize both the extension of water supply pipes and cost reduction. Management associations and facility owners struggling with the maintenance and renewal costs of water supply equipment are encouraged to take a look at our case studies.

In the January 1, 2023 issue of "Air Conditioning Times," No. 2945, an article was published featuring an interview about the effectiveness of the "NMR Pipe Protector," a rust prevention device installed in the piping of the renowned sports club "Vespa Sports Club" in Mie Prefecture, as well as case studies of its implementation. Sports clubs and fitness centers have been hit hard by the impact of the COVID-19 pandemic, but recently they have been recognized as places where people can "enhance their immunity through regular exercise and build a body that is less susceptible to infections," leading to a gradual return of users. However, the recovery trend in user numbers is slow, and the challenge is how to maintain facility functionality while keeping maintenance costs down without compromising service quality. Among these, the maintenance costs for sports clubs with pools and bathing facilities are high, and particularly, aging piping can easily lead to issues such as leaks if left unattended, resulting in enormous costs for pipe replacement. Therefore, this time, the article features the interview content regarding the relatively low-cost installation of the NMR Pipe Protector, which has achieved piping rehabilitation at the renowned sports club "Vespa Sports Club" Matsusaka branch in Mie Prefecture. ▼For more details, please see the related link▼

On November 23, 2022, an article about the calcium scale solidification adhesion prevention device "Non-Scaler" was published in issue 2941 of "Air Conditioning Times." The calcium scale solidification adhesion prevention device "Non-Scaler" has been widely adopted in various factories, including steel mills and paper mills, and has received high praise for its effectiveness. Calcium scale forms when water containing dissolved calcium hydroxide undergoes temperature changes or becomes acidic, causing it to combine with free carbon dioxide in the water or carbon dioxide in the air to create insoluble calcium carbonate crystals. These crystals then solidify and adhere to the inner walls of pumps, boilers, heat exchangers, and piping, forming thick, hard layers. By installing the Non-Scaler introduced here, water is passed through a device equipped with two types of special blades, which forcibly oxidizes the calcium hydroxide in the water and transforms it into fine particles of calcium carbonate. This suppresses the adhesion of scale (calcium carbonate crystals) to the insides of pumps, boilers, heat exchangers, and piping, thereby preventing blade damage within pumps, reducing heat exchange efficiency loss, significantly decreasing the frequency of scale removal work (resulting in substantial maintenance cost reductions), and lowering the frequency of production line stoppages.

On September 16, 2022, an article advertisement for NMR Pipe Protectors was published in the morning edition of the Mainichi Shimbun under the theme "Let's Think About SDGs Together." The article introduces an approach to switching from pipe replacement, which has high CO₂ emissions, to extending the life of pipes with zero CO₂ emissions. By keeping the costs of pipe (replacement) construction in condominiums, schools, water facilities, and government buildings to 1/10 to 1/20 of the usual costs, it aims to ensure access to affordable, reliable, sustainable, and modern energy for all people.

An article from our company has been published on the electronic publishing platform "Medium"! Excerpt from "Everything You Need to Know About the Red Rust Prevention Device 'NMR Pipe Protector'" 1) Common water supply pipes in buildings such as apartments deteriorate over time due to red rust, making the red rust prevention device "NMR Pipe Protector" necessary. All buildings, including apartments, hospitals, hotels, and schools, have plumbing for baths, sinks, kitchens, and laundry. The piping material is generally a steel pipe with a vinyl lining (abbreviated as VLP), which has a layer of polyvinyl chloride on the inside, preventing the iron from coming into direct contact with water and thus preventing the occurrence of red rust. However, while there is no red rust in the straight sections of the pipes, red rust can occur at the joints between pipes, at the connections with copper alloy valves, and at the elbow joints made of copper alloy used to bend the pipes at right angles, as these areas come into contact with water. The joints where the piping connects with various components are fastened with screws, and since the threads are on the iron side, they gradually deteriorate due to red rust, leading to a reduction in the number of remaining threads by about half after approximately 20 years. For more details, please see the related links below.

The September 25, 2021 issue of "Mansion Management Newspaper" No. 1182 featured an article about the NMR Pipe Protector. The "Lions Mansion Koshigaya North" located in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010. Kunio Kitazawa, who was the chairman of the condominium management association at the time, stated, "It has been exactly six years since we introduced it this November. According to the endoscopic inspection, there is no sign of red rust growth, and there is a slight contraction in volume, so we believe that black rust formation is progressing." The long-term repair plan had proposed lining work, but by introducing the NMR Pipe Protector, the actual cost was about one-third of the lining work, allowing the management association to effectively utilize the repair reserve fund for projects such as upgrading lighting fixtures to LED. Mr. Kitazawa mentioned, "A large-scale repair project is scheduled for next year or the year after, and the elevator updates will also be on the schedule. Since the cost of introducing the pipe protector was lower than the board had anticipated, we can allocate funds for these expenses as well."

In Cosmo Kajigaya Le Seine, in 2000, 14 years after its construction, a piping rehabilitation device called "NMR Pipe Protector" was installed to prevent the deterioration of the water supply pipes due to red rust. After conducting a pipe inspection in the 10th year after installation, it was confirmed that the transformation of red rust to black rust had occurred and that the progression of red rust deterioration had completely stopped. Now, 20 years after the installation of the NMR Pipe Protector, and 34 years after construction, there are no issues with red rust in the water supply pipes, and the condition remains excellent.

In August 2001, 23 years after its construction, the Coop Nomura Minami Ishikiri installed a pipe rehabilitation device called "NMR Pipe Protector." The vinyl-lined water supply pipes have a statutory useful life of 20 years, and although 20 years have passed, making it 43 years since construction, they continue to be used without any signs of red rust deterioration. A few years ago, a pipe inspection was conducted, confirming that the red rust had turned to black rust and that the deterioration of the pipes had stopped.

DPE Factory Water Supply Piping This property, built 35 years ago, used galvanized steel pipes for the water supply, which led to leaks and the occurrence of red water due to rust deterioration. A pipe diagnosis by experts indicated a lifespan of only 2 months, prompting the installation of NMR Pipe Protectors on the secondary side piping of the elevated water tank. After installation, since more than 800 tons of water were used daily, the rust prevention effect was quickly realized, resulting in no leaks and the red water issue was resolved within a week. Since then, until the factory's closure in the summer of 2020, the water supply pipes were used for 55 years without any red rust problems. According to the "Life Cycle Cost of Buildings" supervised by the Ministry of Land, Infrastructure, Transport and Tourism, the lifespan of galvanized steel water supply pipes is 15 years, but this became an example of extending their lifespan by 40 years. The main material of the current water supply pipes is vinyl-lined steel pipes, which have less rust deterioration, so the installation of NMR Pipe Protectors is expected to lead to even longer lifespans.

T Building Water Supply Piping According to the "Life Cycle Cost of Buildings" supervised by the Ministry of Land, Infrastructure, Transport and Tourism, the statutory useful life of water supply piping made of galvanized steel pipes is 15 years. However, at T Building in Tokyo, after 37 years since its construction in November 2000, there was a water leak from a part of the water supply pipe, and red water occurred, prompting the installation of NMR Pipe Protectors. Since the installation of the NMR Pipe Protectors, no new leaks have occurred, and the issue of red water has been completely resolved. Now, 20 years later, the water supply pipes have been in use for 57 years since construction, already extending the statutory useful life by 42 years.

The Yokohama City Waterworks Bureau conducted a demonstration test to prevent the occurrence of red rust in water supply pipes and to solve the problem of reduced chlorine concentration in water due to red rust. This was verified using the water supply pipe in the bathroom of Room 102, which was vacant, in the Tsuzumi water reservoir's attached public housing that was 20 years old at the time. The piping materials used were polyethylene-lined steel pipes for shared areas and resin pipes for exclusive areas, where red rust occurred at the pipe joint. The iron concentration in the stagnant water at the bathtub water supply faucet before installation was 0.27 mg/l, and the residual chlorine at that time was 0.11 ppm. Additionally, during the two weeks prior to installation (with water flowing for 3 hours a day), the amount of red rust adhered to the faucet filter was 13 mg/l, indicating significant corrosion of red rust at the pipe joint. After installing the NMR pipe protector on the entire water supply inlet pipe (50A) of the Tsuzumi public housing, the iron concentration in the stagnant water at the bathtub water supply faucet decreased to 0.15 mg/l after one week, while the residual chlorine increased to 0.56 ppm, five times higher than before installation. The NMR pipe protector completely halted the deterioration of red rust, proving that the surface of the existing red rust transformed into passive black rust and that the reduction of chlorine ceased. *You can download the materials for free. *Please feel free to contact us first.

Art museums, museums, cultural centers, libraries, and other places that attract many visitors use energy-efficient warm-type central air conditioning systems, and the materials used are galvanized steel pipes (SGP pipes). After more than 20 years since construction, red rust deterioration progresses. When the threads at the pipe joint parts fall off due to red rust deterioration, water leaks can occur during earthquakes and other events. Additionally, this can lead to problems such as poor heating and cooling efficiency and early failure of heat source equipment. <Benefits of NMR Pipe Protector> 1. Reduces costs by approximately 90% for pipe renewal. 2. Solves the problem of facilities being unusable during pipe renewal work (for more than about 6 months). 3. Addresses the asbestos issue. During air conditioning hot and cold water pipe work in buildings over 30 years old, the disposal of asbestos emitted from places like ceilings becomes a significant problem. Furthermore, the costs associated with this can be as high as those for pipe renewal work, and the construction period may extend by more than 50% of the planned time. The NMR Pipe Protector prevents the occurrence of this asbestos issue. *You can download the materials for free. *Please feel free to contact us first.

"Water supply pipes and chilled/hot water piping require replacement due to aging." After 25 years, the chilled/hot water piping in hospitals experiences red rust deterioration, leading to red rust blockage. Simultaneously, this red rust flows and causes blockage within copper fan coils, reducing the efficiency of heating and cooling. Additionally, the red rust accumulates within the heat source equipment, shortening its lifespan. In the water supply pipes, red rust develops at the joints, and as the red rust deterioration progresses within both pipes, the threads at the joints may break off, leading to leaks during strong earthquakes. "Unnecessary replacement of water supply pipes and chilled/hot water piping." Iron oxidizes and forms red rust due to dissolved oxygen and water molecules in water. When electrons are supplied to the red rust, the water molecules and oxygen contained in the red rust are separated from it, transforming into a very hard black crystal that is one-tenth the volume of the red rust. Because it is black, it is called black rust. Black rust is inert like gold, so if all the red rust in the pipes is converted to black rust, the internal red rust deterioration will cease, preventing external corrosion and extending the lifespan of the building.

In the June 25, 2020 issue of "Mansion Management Newspaper," No. 1141, the introduction of the NMR Pipe Protector at the condominium "Palace Tsurumi" was featured. The condominium "Palace Tsurumi," located in Yokohama City, Kanagawa Prefecture, was completed in January 1972 and consists of 32 units in a five-story building. As a measure against pipe deterioration for the first time in its 39 years, the NMR Pipe Protector from our company was installed. Initially, the management association borrowed from a public financial institution to cover the building's repair costs, making it difficult to undertake pipe replacement due to financial constraints. In this context, the consideration of our NMR Pipe Protector was supported by the existence of a "money-back guarantee if there are no effects," which encouraged them to try it despite their financial situation. After seven and a half years of installation, an endoscopic survey showed a 35.3% improvement in one location compared to before installation, and a 17.4% improvement in another location. Mr. Kanaya, the chairman of the condominium, stated, "Currently, after 48 years, there are no rust issues, and I feel that it is effective. While the building's lifespan may be extended, I see it lasting for 60 years. There are 12 years left until it reaches 60 years, and I hope to prolong its life with the pipe protector until then."

◆Proven Rust Prevention Effect at BBC The rust prevention effect of the NMR Pipe Protector was observed within about a month. Before the introduction of the main block building, the iron content in the circulating water within the pipes was high at 5.53 mg/L, indicating significant red rust deterioration in the piping. However, an inspection 32 days after installation showed that the iron content in the water had drastically decreased to 0.05 mg/L, confirming the rust prevention effect within the pipes. In Stage 5 buildings, the iron content in the water, which was high at 3.80 mg/L before installation, also decreased to 0.06 mg/L after 32 days, demonstrating that the red rust deterioration in the piping was completely prevented. These results prove that even in pipes with significant red rust corrosion, the NMR Pipe Protector exhibits rust prevention effects, enabling the extension of the piping's lifespan. There is no need to give up and assume that the only option is to replace the pipes due to rust prevention devices being too late. The rust prevention effect of the NMR Pipe Protector has allowed many buildings in similar situations to achieve over 40 years of extended piping life. If you are troubled by red rust issues in your pipes, please do not hesitate to contact Japan System Planning Co., Ltd. We also offer free on-site surveys.

◆What is the BBC The BBC (British Broadcasting Corporation) is a public broadcasting organization that operates radio and television in the UK, similar to Japan's NHK, and its main funding comes from viewer license fees. Programs such as "Doctor Who," "Monty Python's Flying Circus," and "BBC News" are well-known in Japan, and recently, more people seem to be watching "BBC News" for language learning purposes. ◆Aging Buildings Due to History The BBC began as the "British Broadcasting Company" in 1922 as a radio station. As a result, many of its buildings have aged significantly, and the main block building, which had the NMR pipe protector installed in 2006, was already 53 years old at that time. The cooling water pipes in the main block used galvanized steel pipes, which have a lifespan of 10 to 20 years, and their lifespan had been greatly exceeded. In fact, there was significant red rust corrosion inside the pipes, necessitating urgent measures. The Stage 5 building also had similar red rust corrosion, and NMR pipe protectors were installed in both buildings. Next time, we will introduce the rust prevention effects at the BBC.

This time, we will introduce the case of the NMR Pipe Protector, a rust prevention device for piping, being implemented by the BBC (British Broadcasting Corporation) in the UK. The feature of the NMR Pipe Protector is its ability to reduce red rust inside the pipes to black rust. It utilizes hydrated electrons (free electrons in water), which are located inside clusters of water molecules. By using the nuclear magnetic resonance of the NMR Pipe Protector and the energy of flowing water to induce discharge, red rust is reduced to black rust. The method of pipe rehabilitation using nuclear magnetic resonance (NMR) is unique to the NMR Pipe Protector. Red rust transforms into black rust, which has a volume that is one-tenth that of red rust, forming a black rust coating inside the pipes. This suppresses the occurrence of new red rust, and because black rust is a very hard crystal, it strengthens the pipes. The technology of coating with black rust has been used for a long time on ironware and has been effective in protecting the iron substrate from red rust for hundreds of years. The NMR Pipe Protector is not only effective in preventing rust but also in reducing costs. For water supply pipes, it can be implemented at one-tenth to one-fifth the cost of pipe replacement, extending the lifespan of the pipes by over 40 years. Next time, we will introduce the BBC, which has implemented the NMR Pipe Protector.

The NMR Pipe Protector (NMRPT) offers more value than just pipe replacement. While replacing pipes addresses the issue of pipe deterioration by replacing them with new ones, the typical lifespan of pipes is around 20 years, after which red rust corrosion will inevitably progress again. Considering that even after spending a significant amount of money on pipe replacement work, which cannot avoid inconveniences in daily life, one can only feel secure for about 20 years, many may question whether pipe replacement is truly the best option. In comparison to pipe replacement, the NMR Pipe Protector can be introduced at a low cost of 1/5 to 1/10, and its rust prevention effect lasts for at least 40 years. Not only does it stop the progression of red rust, but it also transforms existing red rust into hard, water-insoluble black rust crystals, reinforcing the inside of the pipes with a black rust coating. Additionally, the blockage caused by red rust in the pipes is improved because the volume of black rust is 1/10 that of red rust, leading to a reduction in blockage. Thus, compared to pipe replacement, the introduction of the NMR Pipe Protector offers many advantages, and it can be understood as the optimal rust prevention measure against red rust corrosion inside pipes. If pipe replacement is part of future repair plans, it may be worth considering the necessity of such replacement.

The NMR Pipe Protector - NMRPT - solves all the disadvantages of pipe replacement. Water is an essential part of our lives. However, replacing pipes requires water shut-off work, making it difficult to use the bath, toilet, do laundry, or cook, which can easily lead to a stressful living situation. In some cases, the inability to use the toilet or bath may necessitate preparing temporary housing, which can be quite burdensome. If residents express various opinions about the significant impact of pipe replacement work on their lives, will the construction proceed smoothly? As you can see, the impact of red rust corrosion on apartments is quite serious. All these issues can be resolved by introducing the anti-corrosion device, the NMR Pipe Protector. In the case of water supply pipes, the cost of the NMR Pipe Protector is about 1/5 to 1/10 of that of pipe replacement, allowing for significant cost savings. Additionally, the installation of the NMR Pipe Protector does not require a water shut-off and can be completed in about 1 to 2 hours, so there is no impact on residents' daily lives. Next time, we will introduce the anti-corrosion effects of the NMR Pipe Protector.

Piping systems are not often noticed in everyday life, but their role is very important. Regular maintenance and deterioration diagnosis of the piping are essential to detect abnormalities inside the pipes early. Red rust corrosion progresses unnoticed and can lead to "red water," which clouds the water due to the leaching of red rust, "pipe blockages" caused by the increase of red rust, and "leaks" as the corrosion deteriorates the pipes. These risks alone are significant, but there are more points to consider regarding the deterioration of piping. ◆ Pipe replacement is not the best countermeasure against pipe deterioration. The most expensive repair in a building is often the pipe replacement carried out as a countermeasure against red rust deterioration. Depending on the size of the condominium, the cost of pipe replacement can often be several tens of millions of yen, and in larger buildings, it can reach hundreds of millions. Therefore, even if the red rust issue in the piping is discovered, it is not uncommon for the repair reserve funds to be insufficient, making it impossible to carry out the pipe replacement. Even if pipe replacement work can be done, it can significantly disrupt residents' lives, and it is important to be aware of the challenges involved in any case. Next time, we will discuss the impact of pipe replacement work on residents.

This time, we will introduce the effectiveness of the NMR Pipe Protector in reducing plastic waste, which is a cause of marine pollution. A large amount of plastic waste flows into the ocean, causing problems as a source of marine pollution. One of the reasons for this is that in developing countries, due to issues with the quality of tap water, there is a high usage of bottled drinking water, leading to a significant number of discarded plastic bottles. The decline in tap water quality is due to the chlorine used for sterilization to suppress bacteria in the pipes being depleted by red rust corrosion. As a result, the proliferation of bacteria prevents the maintenance of water quality suitable for daily life. However, improvements through pipe replacement are prohibitively expensive and cannot be implemented. The NMR Pipe Protector significantly reduces costs to less than 1/20 of pipe replacement, making long-term extension of the pipes possible. In the Phong Kan area of Binh Phuoc Province, Vietnam, there is already a direct example of improvement in marine pollution. In this area, due to issues with the water quality from the distribution pipes, the introduction of the NMR Pipe Protector has successfully improved the water quality to a level suitable for drinking. By improving the quality of tap water, the use of plastic bottles can be significantly reduced, leading to a solution for the marine pollution problem.

In 2013, the NMR Pipe Protector was introduced to the hot water air conditioning piping in the Todd Building of Christ College. Before installation, the iron content in the circulating water within the pipes was measured at 43.8 mg/L, indicating a high level of rust dissolution. Three weeks after the introduction of the NMR Pipe Protector, inspections showed that the iron content had decreased to 18.0 mg/L, demonstrating significant rust prevention effects. An inspection conducted about a year after installation revealed that the iron content had dramatically reduced to 0.5 mg/L, proving a rust prevention effect of 1/87 compared to the pre-installation level. This result indicates that the rust prevention effect of the NMR Pipe Protector led to the conversion of red rust to black rust within the pipes, resulting in a decrease in the iron content in the water. Considering that the water quality standard set by the Japan Refrigeration and Air Conditioning Industry Association is 1.0 mg/L for iron, the measured value of 0.5 mg/L in the Todd Building indicates good water quality. Thanks to the rust prevention effect of the NMR Pipe Protector, the red rust problem at Christ College has been resolved, allowing for the prolonged lifespan of the piping in the future. To date, the NMR Pipe Protector has proven its rust prevention effects in over 4,200 buildings and has received high praise.

◆Christ's College, which had failed to prevent rust using sacrificial anodes The Todd Building at Christ's College attempted to prevent rust using sacrificial anodes in 2008, before the introduction of the NMR Pipe Protector. Sacrificial anodes work by having the metal that makes up the anode dissolve, preventing oxidation in place of iron. However, the results did not stop the progression of red rust corrosion. Annual applications of rust inhibitors did not change the iron content in the water, and there were concerns about the effects of the rust inhibitors on human health, prompting the consideration of other effective measures against red rust. Consequently, the NMR Pipe Protector, which had proven effective in rust prevention in the UK, was selected and its introduction was decided. The NMR Pipe Protector emits specific electromagnetic waves that induce NMR (nuclear magnetic resonance) in the water flowing through the pipes. This, combined with the kinetic energy of the water, reduces red rust to black rust through the discharge of hydrated electrons (free electrons from water molecules). The robust black rust does not dissolve in water and serves to reinforce the piping. Additionally, the volume of black rust is about one-tenth that of red rust, which helps to reduce and improve blockages caused by red rust. Next time, we will introduce the actual rust prevention effects of the NMR Pipe Protector.
