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.

Lions Mansion Koshigaya North introduced the NMR Pipe Protector in November 2010, resulting in a successful pipe rehabilitation at one-third of the initial estimate. This allowed for effective use of the repair reserve fund for LED lighting upgrades and elevator renovations. According to Mr. Kitazawa, who was the chairman at the time of the NMR Pipe Protector's introduction, an endoscopic survey conducted six years later in 2016 showed no growth of red rust. On the contrary, there was a noticeable reduction in the volume of red rust, indicating progress towards black rust. The NMR Pipe Protector sold by Japan System Planning Co., Ltd. has the property of reducing red rust to black rust by supplying free electrons from water, which leads to a decrease in the volume of red rust and improvement in red rust blockage. Additionally, the inside of the pipes is protected by a strong black rust coating, contributing to the rehabilitation of the pipes. This high anti-corrosion performance has been highly regarded, leading to an increase in the adoption of the NMR Pipe Protector. By implementing the NMR Pipe Protector, maintenance costs for the piping can be significantly reduced, allowing the remaining budget to be allocated to other building facilities.

According to Mr. Kitazawa, who was the chairman at the time of the introduction of the NMR Pipe Protector, it was pointed out that there was red rust occurring at the joints of the water supply pipes during the recent inspection. Therefore, when the board of directors began to consider methods for rehabilitating the pipes, the following options were immediately suggested: 1. Ozone cleaning 2. Citric acid cleaning 3. Electrolytic corrosion prevention 4. Lining method However, when a board member proposed the NMR Pipe Protector, which he had seen in an advertisement on the train, it was determined to be superior to the aforementioned four methods, and the introduction of the NMR Pipe Protector was positively considered. "The idea at the time was that if the current red rust turns into black rust over 40 years with the NMR Pipe Protector, theoretically, the pipes could last an additional 20 to 30 years, totaling 60 to 70 years. In other words, it was calculated that they could last until the lifespan of the building," the board decided to implement it. Once it turns into black rust, scientifically, red rust corrosion does not progress any further, and the volume of red rust itself also shrinks. Additionally, the effectiveness guarantee of the NMR Pipe Protector further supported its introduction. Next time, I will summarize and discuss the rust prevention effects of the NMR Pipe Protector at Lions Mansion Koshigaya North! Please continue to enjoy!

The "Lions Mansion Koshigaya Kita," located in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010, successfully reducing the cost of plumbing maintenance to one-third of the amount originally planned for lining work in the long-term repair plan. At that time, Mr. Kitazawa, who was the chairman, reflected on the situation of the condominium before the introduction and noted that it was essential to cut costs as the management association was in a difficult state. He expressed that he found the introduction of the NMR Pipe Protector, which is said to have a usable life of over 40 years, very appealing. Furthermore, they are effectively utilizing the saved budget to convert lighting fixtures to LED, and they are also considering updating the elevators in the future. In the next installment, we will introduce the background of how Lions Mansion Koshigaya Kita decided to implement the NMR Pipe Protector, as well as its benefits and characteristics. Stay tuned!

◆What is the Royal Garden Hotel London? The Royal Garden Hotel is a popular five-star hotel in London. With 493 guest rooms spread over 14 floors, the top-floor Chinese restaurant "MIN JIANG" offers not only delicious cuisine but also stunning views of the London Eye and the Shard, as well as the River Thames. You can also enjoy the countdown fireworks at the end of the year. The nearest station to the Royal Garden Hotel is High Street Kensington on the underground, and it is conveniently located near tourist attractions such as Kensington Palace, the residence of Prince William and Kate, as well as the popular shopping areas of South Kensington and the Royal Albert Hall. You can also access central locations like Piccadilly Circus by taxi. This prime location is one of the attractions of the Royal Garden Hotel. Next time, we will introduce the issue of red rust in the Royal Garden Hotel's plumbing and the reason for the introduction of NMR pipe protectors! Stay tuned!

◆Reasons for Introducing NMR Pipe Protectors The Royal Garden Hotel was built in 1965, and by the time the NMR Pipe Protectors were introduced in 2007, it had been 42 years since its construction. Due to the deterioration of the hot water supply pipes, relatively dark red water was coming out every morning when turning on the faucet. Additionally, there was constant leakage from the joints of the pipes. Estimates indicated that updating (replacing) the pipes would cost between £6.5 to £7 million (approximately 1 billion yen), including compensation for business interruption. However, it was found that by introducing the NMR Pipe Protectors, the cost could be reduced to £150,000 (approximately 25 million yen), allowing for a remarkable cost reduction to about 1/40 of the original estimate, leading to the decision to implement them. The NMR Pipe Protector utilizes hydration electrons (free electrons in water) to reduce red rust inside the pipes to black rust, which completely prevents the occurrence of red rust with its black rust film. Black rust has been used in southern iron kettles, Chinese woks, and nails or hinges in temples from the Nara and Heian periods, preventing red rust for hundreds of years. By converting all red rust inside the pipes to black rust, the lifespan of the pipes can be significantly extended. Next time, we will introduce the performance of the NMR Pipe Protectors implemented at the Royal Garden Hotel London! Stay tuned for more!

Co-op Nomura Minami Ishikiri, located in Sendai City, Miyagi Prefecture, is a three-story, 24-unit apartment building built in 1978. In August 2001, during its 23rd year, a pipe protector was installed, and it is now 42 years old. Takashi Furuta, the maintenance director who conducted the interview, stated, "Thanks to the rust prevention effect of the NMR Pipe Protector, both the water supply and drainage pipes have been extended in their lifespan, and there are currently no plans for pipe replacement in the long-term repair plan." ◆ Effect of the NMR Pipe Protector on Extending Pipe Lifespan After 16 years of having the NMR Pipe Protector installed, Co-op Nomura Minami Ishikiri conducted a deterioration diagnosis survey of the pipes. It was found that there was almost no red rust deterioration in both the water supply and drainage pipes, and the red rust surface had turned into black rust, confirming the rehabilitation of the pipes. Black rust does not dissolve in water at all and has been used historically in items like Chinese woks. Its small volume improves the blockage caused by red rust, protecting the pipes until the building's lifespan ends. The installation of the pipe protector has eliminated dirt such as limescale and slime, resulting in a 30% reduction in the frequency of drainage pipe cleaning. Furuta mentioned that the amount of red rust discharged during drainage pipe cleaning has also drastically decreased. Additionally, he noted that trust in the NMR Pipe Protector has increased based on the results of the deterioration diagnosis survey of the 40-year-old pipes.

The "Yaesu Exit Hall" in Marunouchi, Chiyoda Ward, Tokyo (built 55 years ago as of 2020) had an NMR pipe protector installed in its air conditioning chilled and hot water piping and cooling water piping five years ago in 2015, when it was 50 years old. We conducted verification to prevent red rust deterioration in the cooling water piping and to extend the life of the piping. Before the installation of the NMR pipe protector, the iron content in the circulating cooling water was 11 mg/l, significantly exceeding the industrial standard of 1 mg/l, confirming the occurrence of red rust. One week after the installation of the NMR pipe protector, the iron content in the same water dropped to less than 0.1 mg/l, significantly reducing it and completely preventing red rust in the piping, while confirming the transformation of red rust to black rust. For the past five years since then, the occurrence of red rust has been completely prevented.

Whittington Hospital, having been built in the 1860s, was experiencing significant deterioration of its buildings. The hot water piping had not been updated for about 30 to 40 years since the last renovation, and every morning, red water was emerging from the piping in the minor surgery room, management room, and sterile room. If this continued, the risk of clogs and leaks due to corrosion in the water pipes would be high. To address this issue, the NMR Pipe Protector was introduced. The NMR Pipe Protector is a device that prevents the formation of red rust inside the pipes and reduces existing red rust to black rust. The NMR Pipe Protector has been on the market for over 25 years, and as of 2020, the number of installations has surpassed 4,200. It is used in a variety of buildings, both domestically and internationally, including government facilities, public facilities, and commercial buildings, in addition to apartments. In the shortest cases, effects can be confirmed within a month. At Whittington Hospital, where it is being introduced, the effects were immediately proven after installation. So what were the results? Let's take a closer look in the next installment.

◆What is Whittington Hospital, where the NMP Pipe Protector has been introduced? Whittington Hospital is one of the largest medical institutions in the UK, located on Highgate Hill in North London. Whittington Hospital is a historic medical institution that was built in the 1860s by merging three hospitals. Originally established in 1745, it was created for the purpose of housing smallpox patients and administering vaccinations. Near Whittington Hospital, there is a stone statue of a cat. This is known as "Dick Whittington's Cat," and it tells the story of a poor boy named Dick Whittington who once lived. He worked on a trading ship, and his pet cat was instrumental in catching mice. As a result, there were numerous requests to "borrow the cat," and he became very wealthy. By the way, the logo of Whittington Hospital also features a cat. I hope you have gained an understanding of the history and overview of Whittington Hospital. Next time, I will provide a detailed introduction to the circumstances surrounding the introduction of the NMP Pipe Protector.

The Royal Bank of Scotland, as one of the leading financial institutions in the UK, owns numerous buildings and has announced a management policy that emphasizes environmental considerations in their maintenance, achieving the world's first chemical-free maintenance. The 250th branch, located in the northeast area of London, Bishopsgate, features a mix of heavy historical buildings and modern structures, and is also noted as a trendsetting location for fashion and art. The 250th branch has a modern stylish exterior in dark gray, but after 18 years since its construction, it faced issues with red rust in the air conditioning hot water piping. The Royal Bank of Scotland had been using rust inhibitors as a countermeasure against red rust, but these inhibitors were costly and, considering environmental concerns, they installed NMR Pipe Protectors in the hot water piping of the 250th branch in March 2018. At that time, the hot water inside the piping was already brown and murky. This concludes the background on why the Royal Bank of Scotland (RBS), a representative megabank in the UK, decided to introduce NMR Pipe Protectors. Next time, I will talk about the performance of the NMR Pipe Protectors introduced at RBS.

The Royal Bank of Scotland, a representative megabank of the UK, has introduced the NMR Pipe Protector and achieved significant cost reductions. The Royal Bank of Scotland, headquartered in Edinburgh, the capital of Scotland, was established in 1722 by a charter from King George I. In 1985, it founded an automobile insurance company and was the first in the UK to launch a telephone insurance sales system. In 1997, it also became the first in the UK to start internet online services. Throughout its long history, it has acquired and merged with over 200 banks while being a pioneering bank that has led the times with innovative ideas. In 2000, it successfully acquired NatWest, one of the four major banks in the UK, becoming a representative bank of the UK in both name and reality. The Royal Bank of Scotland announced in late 2020 that it would change its name to "NatWest," marking the beginning of a new chapter in its history. This concludes our introduction to the Royal Bank of Scotland (RBS), a representative megabank of the UK. In the next installment, we will discuss the pipe rust issue that the Royal Bank of Scotland (RBS) faced and the background behind the introduction of the NMR Pipe Protector.

An article featuring the "NMR Pipe Protector" has been published in the special issue of the newspaper "Mansion Management News" on March 25, focusing on water supply and drainage systems, which targets condominium buildings. The article covers the condominium "Co-op Nomura Minami Ishikiri" in Sendai City, which introduced the "NMR Pipe Protector" 15 years ago. This condominium installed the "NMR Pipe Protector" in 2001, when it was 23 years old, and it has now been 38 years since its construction. According to the maintenance director of the condominium, the installation of the "NMR Pipe Protector" has stopped the deterioration of the red rust in the water supply pipes, improved the deterioration of the drainage pipes, and significantly reduced the frequency of drainage pipe cleaning, as stated in the newspaper interview.
