The air conditioning piping in the BBC's main block building is 53 years old and has been experiencing leaks due to red rust deterioration. To avoid disruptions in program production during the pipe renewal work, a red rust prevention device called the "NMR Pipe Protector" was installed. The effectiveness of the NMR Pipe Protector in preventing red rust was verified in just about a month. Before installation, the iron content in the circulating water of the cooling water piping in the main block building was very high at 5.53 mg/L, indicating serious red rust deterioration. However, a water quality test conducted 32 days after the installation of the NMR Pipe Protector showed a significant reduction to 0.05 mg/L, which is less than 1/100 of the previous value, demonstrating the rust prevention effect due to the black rust formation caused by the NMR Pipe Protector. In the Stage 5 building, the iron content was also very high at 3.80 mg/L before the installation of the NMR Pipe Protector, but after installation, it decreased to about 0.06 mg/L, which is approximately 1/63 of the previous value, completely preventing red rust deterioration in the cooling water piping. Even in the 53-year-old BBC building, the high effectiveness of red rust prevention has been proven to prevent leaks and extend the life of the piping. *For more details, please refer to the PDF document or feel free to contact us.*

At the Nihon University College of Engineering campus in Koriyama City, Fukushima Prefecture, the water supply pipes in several research buildings were significantly deteriorated due to red rust, resulting in red water coming out of the taps on holidays and the following days. To reduce future piping renewal costs by 1/5 to 1/10, a red rust prevention device called the "NMR Pipe Protector" was installed. The results of an inspection conducted one month after installation clearly demonstrated the excellent performance of the NMR Pipe Protector. The iron content in the water due to red rust decreased to less than 1/10 of the pre-installation level (from 7.8 mg/L before installation to 0.1 mg/L after installation). Initially, the iron content was at 7.8 mg/L, exceeding the water quality standard value set by the Water Supply Act (0.3 mg/L), indicating a very serious progression of red rust. However, after installation, the levels were significantly below the standard, proving the rust prevention effect through the blackening of red rust and the extension of pipe life. The water quality was remarkably restored to a hygienically satisfactory level. The NMR Pipe Protector is an exceptionally effective rust prevention device that saves energy in creating new piping, thereby reducing environmental burden. *For more details, please refer to the PDF document or feel free to contact us.*

The Kagurazaka campus of Tokyo University of Science was 26 years old at the time. The water supply pipes were made of PVC-lined steel pipes, and serious red rust blockages had occurred at the joints of the water supply pipes. Before the installation of the NMR Pipe Protector, an inspection of the red rust blockage rate in the toilet water supply piping revealed that the blockage rate was 35%, indicating significant red rust deterioration. After the introduction of the NMR Pipe Protector, a re-inspection was conducted at the same location 10 months later. The results showed that the red rust blockage rate had decreased to 31%, and it was verified that the red rust was gradually changing from a volume of 1/10 of black rust from the surface. At Tokyo University of Science, the NMR Pipe Protector was introduced to extend the lifespan of the piping in buildings and facilities that were originally scheduled for replacement in 10 to 15 years.

At the Legend Hotel Saigon (now Lotte Hotel Saigon) in Vietnam, severe red water emerged from the water supply pipes just six years after its construction. Despite running the water for an extended period, there was no sign of improvement, leading to a situation where guests could not even take a shower. The water in Vietnam contains a high level of sulfuric components, making it very prone to red rust formation when it reacts with galvanized steel pipes (SGP). In response, in 2008, a red rust prevention device called the "NMR Pipe Protector" was installed in the water supply piping. Before the installation, red water was coming from all the water faucets in the hotel. However, about a month and a half later, water quality checks in the sinks, baths, and toilets of ten guest rooms on the 14th to 17th floors showed that almost all the water supply had become clear, confirming the effectiveness of the red rust prevention. The corrosion of red rust in the water supply pipes was halted, and it was successfully transformed into black rust. This demonstrated that even in water with a high sulfuric content that easily corrodes water supply pipes, the red rust could be converted to black rust, exhibiting a high level of rust prevention effectiveness. *For more details, please refer to the PDF document or feel free to contact us.*

The "Palace Tsurumi" condominium in Tsurumi Ward, Yokohama City, Kanagawa Prefecture, has introduced the red rust prevention device "NMR Pipe Protector" in its 39th year since construction. This is the first implementation of measures against red rust deterioration in the water supply pipes since the building was completed. The management company proposed updating the piping with stainless steel pipes as a measure against water supply pipe deterioration. However, due to the repayment of loans from exterior wall repair work and a shortage of reserve funds, it was difficult for the management association to proceed with the piping update. The management association approved the introduction of the NMR Pipe Protector at the general meeting because it came with a guarantee that "if it does not work, we will refund you." The red rust prevention device "NMR Pipe Protector" quantitatively measures its effectiveness to provide an objective evaluation of its rust prevention effects. As the red rust gradually transforms into black rust with a volume reduction of 1/10 due to the NMR Pipe Protector, the Palace Tsurumi conducted an endoscopic investigation of the red rust blockage rate at two locations in the seventh year after installation, showing a reduction in blockage rates of 35.3% and 17.4% compared to before installation. Even without maintenance of the piping for 39 years since completion, the NMR Pipe Protector demonstrated its rust prevention effectiveness. *For more details, please refer to the PDF or feel free to contact us.*

In the year 2000, 13 years after its completion, C University Library discovered that there was water leakage due to red rust deterioration in part of the chilled and hot water piping of the library's air conditioning system. The circulating water was mixed with red rust, and the deterioration of the piping had progressed significantly. As a rust prevention measure within the piping, rust inhibitors were regularly administered, but the red rust deterioration did not stop, and since 1996 (9 years after construction), partial updates of the piping had been underway. However, due to the presence of asbestos in the ceiling of the library, it was difficult to carry out renewal work on the main and branch pipes. Therefore, the installation of the rust prevention device "NMR Pipe Protector" was introduced. The NMR Pipe Protector stops the red rust deterioration of the piping and can extend the life of the piping until the building's lifespan, making the removal of asbestos unnecessary and allowing for significant cost reductions. Since the installation work of the NMR Pipe Protector does not require water shutdown, construction could proceed while the building was in use, eliminating the need for the library and surrounding facilities to suspend operations. After the installation at C University Library, the rust prevention effect within the chilled and hot water piping was confirmed by the increase in the amount of black rust in the red rust. After the introduction of the NMR Pipe Protector, the piping was removed, and quantitative analysis of rust samples demonstrated the transformation of red rust to black rust.

The building housing the famous bookstore in Shinjuku is always bustling with many people. About 20 years ago, we were troubled by the deterioration of the air conditioning chilled and hot water piping due to red rust. Because asbestos was used in the ceiling, it was practically impossible to carry out piping replacement work. As an alternative to piping replacement, we introduced the 'NMR Pipe Protector,' a device that can be installed on the outside of the piping to extend its lifespan by over 40 years. A pipe inspection, which involves removing a section of the piping for examination, was conducted 19 months after the installation of the NMR Pipe Protector. The results showed no signs of red rust corrosion on the inner surface of the piping, and the conversion of red rust to black rust was confirmed, indicating a very good condition of the piping. The building is already 57 years old, but the galvanized steel piping used for the air conditioning chilled and hot water system, which has been in use since its completion, has shown no leaks, and a follow-up survey in 2020 confirmed that there has been no occurrence of red rust since the installation of the NMR Pipe Protector. *For more details, please refer to the PDF document or feel free to contact us.*

The NMR Pipe Protector has been widely adopted as a device for preventing red rust and extending the life of piping, and it has recently gained attention in the water distribution pipes of water supply authorities. At the Japan Water Works Association's water supply research presentation held in 2013, the Yokohama City Water Bureau published a paper presenting the results of a demonstration experiment showing that the use of this product can suppress the decrease in chlorine concentration in tap water. This matter was also reported as an article in the Japan Water Newspaper. The initial verification confirmed a decrease in iron ion levels in the water and an increase in residual chlorine concentration before and after installation in the water supply pipe of the public housing attached to the Tsurumi water supply reservoir. Next, a comparison of residual chlorine concentrations was conducted, revealing that before installation, the chlorine concentration was 0.5 PPM in the test pipe located 10 meters from the main pipe, 0.3 PPM at a distance of 60 meters, and 0.2 PPM at 135 meters, indicating that the residual chlorine concentration decreased with increasing distance due to red rust in the piping. After the installation of the NMR Pipe Protector, it was confirmed that the chlorine concentration at 135 meters doubled. From these test results, the effectiveness of suppressing the decrease in chlorine concentration was verified, demonstrating that the NMR Pipe Protector can also be used to prevent red rust deterioration in the main water supply pipes. *For more details, please refer to the PDF or contact us.*

The anti-rust device for pipes, "NMR Pipe Protector," was featured on TV Tokyo's economic information program "World Business Satellite (WBS)." The water treated by the NMR Pipe Protector has a smaller cluster size, which promotes the growth of vegetables, leading to verification in the agricultural sector. At "Mitsu Village" in Himeji City, Hyogo Prefecture, NMR Pipe Protectors are installed in the piping that delivers water to greenhouses. In the program, the weight of tomatoes grown with regular water was compared to those grown with water from the supply pipe equipped with the NMR Pipe Protector, and on average, the latter tomatoes were 16 grams heavier. From previous verifications, it has been found that growing tomatoes with water from supply pipes equipped with the NMR Pipe Protector increases the yield by approximately 7 percent. In this way, the NMR Pipe Protector is expected to leverage its ability to change the properties of water and expand into various fields. *You can download the materials for free. *Please feel free to contact us first.

It is said that the plastic waste polluting the oceans amounts to about 8 million tons. Developing countries with densely populated cities, such as Indonesia and Vietnam, are major contributors to the marine plastic waste problem due to their high consumption of bottled beverages, much of which flows into the oceans through rivers and other waterways. The high consumption of bottled beverages is due to the unsuitability of tap water for drinking. If the water quality issues of tap water in developing countries are resolved, there is a prospect of improving the marine pollution problem caused by plastic waste. What is expected in this regard is our company’s uniquely developed rust prevention device for pipes, the 'NMR Pipe Protector.' This product can resolve the rust issue in water pipes faced by developing countries at a cost of one-tenth to one-twentieth of pipe replacement, improving the water quality to make it drinkable.

The "Lions Mansion Koshigaya North" located in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010. This successfully reduced the cost of pipe maintenance to one-third of the amount originally planned for lining work in the long-term repair plan. Before the installation of the NMR Pipe Protector, and one year, five years, and ten years after installation, the red rust blockage rate at the dissimilar metal joints, where red rust deterioration progresses the most, was continuously inspected, confirming that the red rust blockage rate decreased over time. This indicates that the red rust is gradually transforming into black rust, which is one-tenth the volume. This has proven that the water supply pipes can be extended to the lifespan of the building. The management association effectively utilized the saved budget for LED lighting upgrades and other repairs. In addition to the LED lighting upgrades, the renewal of elevators is also being considered in the future. As a result, the NMR Pipe Protector has become a savior for the condominium. It has significantly reduced the costs of pipe maintenance, allowing the remaining budget to be allocated to other building facilities. **Results of the NMR Pipe Protector:** - No growth of red rust was observed in the endoscopic survey conducted six years after installation. - A reduction in the volume of red rust was observed, indicating progress in the transformation to black rust.

At that time, Buckingham Palace was using galvanized steel pipes for air conditioning hot water piping and hot water supply piping, but due to deterioration from red rust, partial updates to the piping were being carried out in areas outside of Her Majesty's usage. The circulating hot water in these pipes installed for Queen Elizabeth's room had been reddish-brown due to red rust since it was first used. Therefore, to make this reddish-brown water clear and to prevent red rust, as well as to extend the life of the piping, the 'NMR Pipe Protector' was introduced. In the hot water supply piping, the level was reduced from 2.8 mg/L before installation to below 0.018 mg/L, which is less than 1/100, after 24 days, demonstrating the effectiveness of red rust prevention. Additionally, the color of the water became clear, and the NMR Pipe Protector fully exhibited its high performance in preventing red rust. *For more details, please refer to the PDF document or feel free to contact us.*

The "NMR Pipe Protector" was installed on the secondary side of the main hot water piping pump in the boiler room located in Area F of the British Museum. Before installation, the amount of red rust in the air conditioning hot water was significantly advanced, measuring 20 mg per liter. After five weeks of installation, the amount of red rust in the water decreased to 0.2 mg per liter, a reduction to one-hundredth, demonstrating the effectiveness of preventing red rust through its black rust transformation. As a result, the British Museum was able to not only avoid damage and the risk of water leaks caused by red rust but also reduce the risk of red rust affecting future exhibits. Due to the high risk of damaging exhibits, construction work such as replacing piping facilities could not be carried out, and the use of anti-rust agents would adversely affect the condition of the paintings. Therefore, the NMR Pipe Protector was the only method that the museum could adopt. With the NMR Pipe Protector, there were no impacts on the exhibits, and the British Museum was freed from the risks of red rust. *For more details, please refer to the PDF document or feel free to contact us.*

Currently, at the Imperial Theatre, which has been standing for 56 years, the "NMR Pipe Protector" was introduced in 2000 (Heisei 12), marking 34 years since its construction, with the aim of preventing corrosion of the building's piping and rehabilitating it. The Imperial Theatre building has its own heating source equipment for air conditioning, and the machine room is located at the deepest point, the sixth basement level. Renovations and maintenance of various components, such as water-based piping that is prone to aging, have been carried out quite frequently. However, while exposed piping and equipment in the machine room have been manageable, the buried piping could not be addressed. The effects of introducing the NMR Pipe Protector have been tremendous. This year marks 56 years since its construction, and the occurrence of red rust inside the piping has been remarkably suppressed. Additionally, there has been no leakage for the past 22 years since the installation of the product, proving that the red rust has transformed into black rust. As a result, the NMR Pipe Protector has contributed to maintaining a comfortable theatrical environment at the Imperial Theatre, which symbolizes Japan's theatrical culture. *For more details, please refer to the PDF document or feel free to contact us.*

Kumamoto Red Cross Hospital, being a long-established medical institution, faced issues due to the aging of its facilities. One of the significant problems that could not be ignored was the "deterioration of piping due to red rust." One of the issues caused by the deterioration of the air conditioning hot and cold water pipes is "leakage." In a high-level medical facility, leakage can lead to the malfunction of medical equipment and is certainly undesirable from a hygiene perspective. In response, in 2014, the 'NMR Pipe Protector' was introduced as a measure to prevent piping deterioration, and its effectiveness was recognized, leading to its implementation throughout the entire facility. In a water quality survey conducted before the installation of the NMR Pipe Protector, the iron content due to red rust in the hospital's air conditioning hot water was found to be 12.3 mg per liter, indicating significant red rust presence. However, just two weeks after the installation of the NMR Pipe Protector, this amount decreased to 0.07 mg, demonstrating a reduction of approximately 82% in concentration, and proving that the red rust had transformed into insoluble black rust in the water. Not only were we able to protect the medical environment from leakage caused by red rust, but we also became able to allocate more budget to other areas. *For more details, please refer to the PDF document or feel free to contact us.*

The "NMR Pipe Protector" has garnered attention worldwide for its ability to solve the problem of red rust. Every morning, red water would come out from the hot water pipes at Guildhall, London. When we measured the iron content in the water, it was found to be 6.36 mg per liter, indicating significant red rust, which is considerably higher than the water quality standard of 0.2 mg per liter based on UK water regulations. Three weeks after the installation of the NMR Pipe Protector, the iron content in the water was measured at 0.015 mg per liter. This is 1/400 of the iron content before installation, and when measured seven weeks after the installation of the NMR Pipe Protector, it further decreased to 0.007 mg per liter, which is less than half of the value three weeks prior, proving that the red rust had transformed into insoluble black rust in the water. As a result of the drastic reduction in iron content, the red water was eliminated. The existing red rust was reduced to black rust, which strengthened the piping. As long as the building continues to exist, the piping can continue to be used. Since the red rust problem in the hot water pipes at Guildhall, London has been resolved, a letter of recommendation was issued. *We are currently offering free PDF materials such as customer testimonials (customer recommendation letters)!

As an example of the introduction of the "NMR Pipe Protector," we would like to present the case of the Royal Bank of Scotland. Branch 250 had been in operation for 18 years and was facing issues with red rust in the air conditioning hot water piping. Due to the high cost of rust inhibitors and the shift towards environmental considerations, the "NMR Pipe Protector" was installed in the air conditioning hot water piping in March 2018. As a result of the installation, the iron content in the hot water, which was previously 1.10 mg/L due to red rust, was re-examined nine weeks after the installation of the NMR Pipe Protector, revealing that the hot water was clear and the amount of dissolved iron had decreased to approximately one-third, or 0.41 mg/L. The progression of red rust within the piping also stopped, and the red rust had transformed from a surface state to black rust. The NMR Pipe Protector successfully resolved the issue of red rust dissolving into the water and halted its progression. There is now no longer a concern about the acceleration of piping deterioration due to red rust. Additionally, the coating of black rust has a reinforcing effect on the piping, and it is expected to extend the lifespan of the piping to match that of the building. *Customer feedback (customer testimonials) and other PDF materials are currently available for free! *Please feel free to contact us first.

In the condominium "Cosmo Kajigaya Le Seine," which introduced the NMR Pipe Protector, polyvinyl chloride lined steel pipes (VLP) were used for the water supply piping. Polyvinyl chloride lined steel pipes (VLP) are pipes that are internally coated with polyvinyl chloride. The joint sections of the piping deteriorate due to red rust, but the straight sections are excellent in durability and corrosion resistance, and are currently used in most buildings' water supply pipes. However, this water supply piping has high maintenance costs, and after several decades of installation, measures against water leaks due to red rust at the joints are necessary. Many water supply pipes experience issues such as red rust blockage at the joint sections, water leaks, and deterioration of water quality after twenty years. The NMR Pipe Protector converts red rust into black rust, resolving these issues. Unlike pipe renewal work, the NMR Pipe Protector can be installed without water interruption, transforming the red rust inside the water supply pipes into black rust that strengthens the piping. By introducing the NMR Pipe Protector, red rust becomes inert black rust, extending the lifespan of the piping by over 40 years. *For more details, please refer to the PDF materials or feel free to contact us.

The Royal Garden Hotel London is beloved by travelers from around the world as one of the leading five-star hotels. Constructed in 1965, by 2007, it had been 42 years since its establishment, and the deterioration of the hot water supply pipes had progressed. Due to the use of iron pipes, internal rust corrosion had advanced, resulting in relatively dark red water emerging every morning when the tap was turned on. To address this, three "NMR Pipe Protectors" were installed on the main hot water supply pipe in the boiler room. Before installation, two weeks after installation, and then monthly for 12 months, water quality tests were conducted to measure the iron content in the water due to rust. As a result, it was found that the iron content in the water within the pipes had significantly decreased immediately after installation. Since the effectiveness of rust prevention was quantitatively proven, the hotel also installed NMR Pipe Protectors in the air conditioning pipes. Ultimately, while the cost of pipe renewal was approximately 1.5 billion yen, the total cost of the NMR Pipe Protectors was about 30 million yen, resulting in a cost that was 1/50 of the original estimate. In terms of cost-effectiveness, it far exceeded the hotel's expectations. *Customer feedback (customer testimonials) and other PDF materials are available for free! *Please feel free to contact us first.

The red rust prevention device "NMR Pipe Protector" is an excellent product that reduces red rust to black rust and strengthens piping. Red rust has the property of generating red water and corroding pipes until they become deteriorated. Co-op Nomura Minami Ishikiri installed the NMR Pipe Protector in August 2001, marking its 24th year. After 15 years, a deterioration diagnosis survey of the piping was conducted. When the drainage pipes on the secondary side of the elevated water tank and inside the residences were inspected, it was found that there was almost no progression of red rust due to internal deterioration in both the water supply and drainage pipes. Thanks to the effect of the NMR Pipe Protector, red rust had hardly progressed, and its surface had turned to black rust, ensuring proper rehabilitation of the piping. Similarly, the drainage pipes showed almost no progression of red rust, earning high praise. *For more details, please refer to the PDF document or feel free to contact us.*

The British Museum has undergone multiple renovations over the years, but the building is over 264 years old. It is an important museum that needs to continue to exist in the future, but the issue of building deterioration cannot be avoided. One of those issues was the concern of leaks due to the deterioration of the heating hot water piping caused by red rust. In March 2016, we verified whether the 'NMR Pipe Protector' is truly an effective measure against red rust in piping by installing one unit on the air conditioning hot water piping and conducting tests on the iron content in the same circulating hot water before and after installation. Before the installation of the NMR Pipe Protector, the iron content in the water was very high due to red rust. Three weeks after installation, it measured 3.44 mg/L, and five weeks after installation, it dropped significantly to 0.2 mg/L, proving the effectiveness of red rust prevention as it matched the drinking water standard of 0.2 mg/L. It has been recognized that if the NMR Pipe Protector continues to be used, the lifespan of the piping can be extended to match the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.*

The exterior of the building does not reveal the condition of corrosion deterioration of the threads. If corrosion deterioration of the threads progresses unnoticed, it can lead to pipes coming loose and causing water leaks due to shocks during earthquakes. To maintain the seismic strength of the piping, it is necessary to perform rust prevention treatment inside the pipes before the threads deteriorate due to red rust. Our internal rust prevention device, the 'NMR Pipe Protector,' can improve various red rust issues inside the pipes by reducing red rust to black rust. Not only does it provide rust prevention effects, but the transformation of red rust to black rust also strengthens and rehabilitates the piping. For the safety of our customers, it is advisable to recheck the seismic strength of the building's piping and take prompt action to prepare for earthquakes at any time. *For more details, please refer to the PDF materials or feel free to contact us.

The water supply pipes in buildings such as condominiums are made of vinyl-lined steel pipes, so the straight sections do not deteriorate; only the joints experience red rust deterioration. Since there is no change in the color of the water coming from the faucet and no red water is produced, it is difficult to notice the red rust deterioration inside the pipes. Our company will first conduct an on-site inspection using an endoscope to investigate the customer's red rust deterioration status, and based on that, we will propose the optimal introduction of the "NMR Pipe Protector." With this product, it is possible to prevent red rust deterioration throughout the entire piping, including the joints. By introducing this product, we can eliminate the need for piping replacement costs, which can be a significant financial burden for customers within limited repair budgets, and extend the life of the existing pipes for over 40 years, thereby prolonging the lifespan of the pipes until the building's lifespan ends. *For more details, please refer to the PDF materials or feel free to contact us.

In addition to pipe rehabilitation, there is the "NMR method," which uses our internal rust prevention device, the "NMR Pipe Protector," to reduce red rust to insoluble and passive black rust in water. Vinyl-lined steel pipes are commonly used for condominium water supply piping, where the straight sections do not deteriorate from red rust, but only the joints do. By converting this red rust to black rust, pipe renewal becomes unnecessary, reducing costs to 1/5 to 1/10. The NMR Pipe Protector utilizes free electrons in water to convert internal red rust to black rust. Since the NMR Pipe Protector is installed on the outside of the pipe, it does not come into direct contact with the water inside, making it hygienic and safe. Through on-site surveys by our technical workers, we can implement our product at suitable installation locations, allowing for appropriate pipe rehabilitation throughout the entire piping system. The NMR method has obtained a patent as a groundbreaking pipe rehabilitation technique and has been presented in research papers at the "Asia-Pacific Corrosion Society" and the "Japan Society of Corrosion Engineering," receiving positive evaluations. It has been highly regarded for its water quality safety and has been adopted in many renowned hospital facilities around the world. The NMR Pipe Protector comes with a rust prevention effect guarantee, so you can implement it with confidence. *For more details, please refer to the PDF or contact us.*

In the year 2000, at a major DPE factory that was 35 years old at the time, the pipe lifespan was diagnosed to be 2 months, and our company's 'NMR Pipe Protector' was introduced into the water supply piping. The iron content in the water that had been stagnant overnight was measured at 0.5 mg/L before the introduction, which was unsuitable for water used in DPE. However, just 6 days after the introduction of our product, the iron content in the water decreased to less than 0.05 mg/L, which is one-tenth of the previous level, due to the black rust formation from red rust. Since then, the water quality has further improved, with the iron content in the water dropping below 0.03 mg/L, confirming the effectiveness of rust prevention. As of 2019, this water quality has been maintained. Additionally, no new leaks have occurred since the introduction.

To extend the lifespan of existing piping until the lifespan of the building, if the red rust that occurs inside the piping is converted to black rust without being flushed away, the lifespan of the piping can be prolonged to match that of the building. When extending the lifespan of piping, methods such as cleaning the piping or sandblasting to remove red rust can damage the interior of the piping, reducing its strength. With our internal red rust prevention device, the 'NMR Pipe Protector,' it is possible to convert red rust to black rust without direct contact with the water inside the piping. By utilizing NMR (nuclear magnetic resonance), it is possible to prevent the deterioration of red rust inside the piping and also to rehabilitate and strengthen the piping. It is suitable for preventing red rust in water supply piping (vinyl-lined steel pipes) and air conditioning hot and cold water piping (galvanized steel pipes), as well as for rehabilitating and strengthening piping. *For more details, please refer to the PDF materials or feel free to contact us.

On January 12, 2007, in one of the six pump rooms located within Buckingham Palace, only one pump room supplying Her Majesty's room was equipped with an "NMR Pipe Protector" for the air conditioning hot water piping and the hot water supply piping. Before the installation of the NMR Pipe Protector, the iron ion concentration in the circulating hot water of the air conditioning hot water piping for Her Majesty's room was measured at 16.6 mg/L, indicating a high level of iron ions and a significant presence of red rust within the piping. Subsequently, 24 days after the installation of the NMR Pipe Protector, the iron concentration in the hot water of the air conditioning hot water piping decreased to 0.455 mg/L. The piping was completely protected from red rust by the NMR Pipe Protector, extending the lifespan of the piping, which has been greatly appreciated by those associated with Buckingham Palace for security reasons. *Customer testimonials (customer recommendations) and other PDF materials are currently available for free! *Please feel free to contact us first.

In August 2001, we introduced the "NMR Pipe Protector" to the Co-op Nomura Minami Ishikiri condominium in Wakabayashi Ward, Sendai City, Miyagi Prefecture. After 15 years, an investigation into the deterioration of the piping was conducted. The investigation involved removing the water supply pipes on the secondary side of the elevated water tank and inside the residences, as well as the drainage pipes. It was evaluated that "there was almost no red rust due to internal deterioration of the water supply pipes, and there were no blockages; it was confirmed that the surface had turned black and that pipe rehabilitation had been carried out." The condominium's maintenance director stated during an interview, "Not only the water supply pipes but also the drainage pipes have been extended in their lifespan, and there are no plans for updates in the long-term repair plan." He added, "As the building ages, it will only become more financially challenging in the future, so the benefits of not having to update the water supply pipes are immeasurable." *For more details, please refer to the PDF document or feel free to contact us.

The red rust prevention device for piping, "NMR Pipe Protector," has obtained patents and registrations in the United States and major countries around the world after undergoing rigorous patent examinations abroad regarding its practicality and other factors. On February 16, 2004, the first installation in the UK was at Addenbrooke's Hospital, affiliated with the University of Cambridge. The NMR Pipe Protector holds a patent in the UK and established its reliability through presentations at conferences related to "corrosion," leading to its installation based on a recommendation from the University of Cambridge. At Addenbrooke's Hospital, the hot water pipes experienced leaks due to bacterial corrosion and red rust deterioration just three years after the piping was updated. However, after the installation of the NMR Pipe Protector, red rust in the galvanized steel hot water piping was prevented in just 11 days. The iron ion concentration due to red rust in the hot water decreased from 1.07 mg/L before installation to 0.188 mg/L after 11 days, falling below the water quality standard of 0.2 mg/L. This change, where the red rust in the hot water pipes transformed into black rust with a volume reduction of one-tenth, verified the red rust prevention effect of the NMR Pipe Protector. 【Case Studies (Partial)】 ■ Addenbrooke's Hospital ■ St Thomas' Hospital ■ Harrods Department Store ■ BBC (British Broadcasting Corporation)
