The "seismic strength" of water supply piping deteriorates over time due to the loss of thread integrity.

The "seismic strength" of water supply piping deteriorates over time due to the loss of thread integrity.

The red rust prevention device "NMR Pipe Protector" prevents the reduction of seismic strength in water supply and air conditioning pipes by converting red rust into hard black rust.

The condition of corrosion deterioration of the screw threads cannot be determined from the exterior of the building. If corrosion deterioration of the screw threads progresses unnoticed, it can cause pipes to come loose and lead to water leaks due to shocks during earthquakes. To maintain the seismic strength of the piping, it is necessary to perform anti-corrosion treatment inside the pipes before the screw threads are reduced due to red rust deterioration. Our anti-red rust device for piping, 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 anti-corrosion effects, but the transformation of red rust to black rust also strengthens and rehabilitates the piping. For the safety of our customers, it is wise to reconfirm 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 document or feel free to contact us.

Cosmo Kajigaya Le Seine introduces NMR pipe protectors to prevent piping red rust.

Cosmo Kajigaya Le Seine introduces NMR pipe protectors to prevent piping red rust.

The management association of "Cosmo Kajigaya Le Seine" has verified the prevention of red rust deterioration in water supply pipes using the red rust prevention device "NMR Pipe Protector," ensuring long-term pipe longevity.

In the condominium "Cosmo Kajigaya Le Seine," where the NMR Pipe Protector has been introduced, polyvinyl chloride lined steel pipes (VLP) were used for the water supply piping. Polyvinyl chloride lined steel pipes (VLP) refer to pipes that are internally coated with polyvinyl chloride. While the joints of the pipes are prone to red rust deterioration, 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 become necessary. Many water supply pipes experience issues such as red rust blockage at the joints, 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 replacement work, the NMR Pipe Protector can be installed without water service interruption, transforming the red rust inside the water supply pipes into black rust that strengthens the pipes. By introducing the NMR Pipe Protector, red rust becomes inert black rust, extending the lifespan of the pipes by over 40 years. *For more details, please refer to the PDF materials or feel free to contact us.

Pipe rust prevention, the Royal Bank of Scotland has introduced the NMR Pipe Protector.

Pipe rust prevention, the Royal Bank of Scotland has introduced the NMR Pipe Protector.

The Royal Bank of Scotland confirmed the rust prevention and lifespan extension effects of NMR pipe protectors for air conditioning piping, reducing piping renewal costs to less than one-tenth.

As an example of the introduction of the "NMR Pipe Protector," we 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 costs of rust inhibitors and a 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 value from red rust in the hot water, which was 1.10 mg/L before installation, was re-examined 9 weeks after the installation of the NMR Pipe Protector, revealing that the hot water was clear and the amount of dissolved iron in the hot water had decreased to approximately 1/3, 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 from black rust has a reinforcing effect on the piping, and it is expected to extend the lifespan of the piping to match the lifespan of the building. *Customer feedback (customer testimonials) and other PDF materials are currently available for free! *Please feel free to contact us first.

The NMR Pipe Protector was featured on the business program "Corporate Spirit."

The NMR Pipe Protector was featured on the business program "Corporate Spirit."

There are over 4,200 installations! The red rust prevention device for pipes, "NMR Pipe Protector."

The piping anti-rust device "NMR Pipe Protector" was introduced on the Tokyo MX business program "Corporate Spirit." This product has the function of transforming red rust into black rust. By reducing the size of water aggregates and utilizing free electrons in the water, it reduces red rust in the piping to black rust. While suppressing the occurrence of new red rust, it reduces existing red rust to black rust, thereby strengthening the piping itself. Black rust forms a dense film on the surface of iron, protecting it from red rust, which corrodes iron. It has been used as a rust preventive since ancient times and is still used today for coatings on iron products such as Nambu iron kettles and Chinese woks. This product leverages the advantages of black rust to extend the lifespan of piping. [NMR Pipe Protector Features] ■ Can fundamentally solve the red rust problem ■ Excellent cost performance ■ Installation work is small-scale (no need for water stoppage) *For more details, please refer to the PDF materials or feel free to contact us.

Pipe rust prevention, the BBC in the UK has introduced the NMR pipe protector.

Pipe rust prevention, the BBC in the UK has introduced the NMR pipe protector.

Preventing red rust in the air conditioning pipes of the BBC in the UK, extending the life of the pipes by preventing leaks with the red rust prevention device 'NMR Pipe Protector'

The air conditioning piping in the main block building of the BBC (British Broadcasting Corporation) is 53 years old and has been experiencing leaks due to red rust deterioration. To avoid disruptions in program production during the pipe replacement 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 one 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, confirming 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 approximately 0.06 mg/L, which is about 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.*

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (1)

The Yokohama City Waterworks Bureau has verified the effectiveness of the NMR pipe protector in preventing red rust and reducing chlorine levels for disinfection in the water supply pipes at the Tsurumi public housing.

At the Yokohama City Waterworks Bureau, a demonstration test was conducted at the 20-year-old Tsurumi water reservoir's attached public housing to prevent red rust from occurring in the water supply pipes, thereby solving the problem of reduced chlorine concentration in the water due to red rust. The test was carried out using the water supply pipe in the vacant bathroom of room 102. The piping materials used included polyethylene-lined steel pipes in the shared areas and resin pipes in the exclusive areas, where red rust was found to be occurring at the pipe joint sections. Before the installation of the NMR pipe protector, the iron concentration in the stagnant water at the bathtub water supply faucet during nighttime was 0.27 mg/L, with a residual chlorine level of 0.11 ppm at that time. Additionally, over the two weeks prior to installation (with water flowing for 3 hours a day), the amount of red rust accumulated on the faucet filter was 13 mg/L, indicating that corrosion due to red rust at the pipe joint sections was significantly advanced.

[NMR Pipe Protector Verification Results] Water Supply Pipe in Binh Phuc Province, Vietnam

The red rust inside the cast iron water supply pipe has turned into black rust! It has been proven that the leaching of red rust into the water has been completely prevented.

In the Huong Canh area of the Water Supply Bureau in Binh Phuc Province, Vietnam, cast iron pipes (150A) have been in use for 15 years, leading to the progression of red rust corrosion inside the pipes, which resulted in the regular occurrence of red water. To address this red water issue, a red rust prevention device called the "NMR Pipe Protector" was installed at the base of the cast iron water supply pipes (150A). Before installation, the water color and the amount of red rust at the sampling points located 500m north, 300m west, and 600m south of the installation site were as follows: the northern point had a light brown color with 7.0 mg/l of red rust, the western point had a brown color with 8.0 mg/l, and the southern point had a dark brown color with 23 mg/l. Two weeks after installation, the northern point showed a lighter color and a reduction in red rust to 4.6 mg/l. The western point nearly lost its color, decreasing to 2.0 mg/l. The southern point changed to a light brown color with a reduction to 12 mg/l. *For more details, please refer to the PDF document or feel free to contact us.*

[NMR Pipe Protector Verification Results] Izu Ohni Country Club

The progress of red rust completely stopped just one month after installation! A case where the discoloration of the filter also decreased!

This property has been in existence for 33 years, and due to significant red rust blockage at the joints of the water supply pipes made of different metals, we adopted the pipe rehabilitation device "NMR Pipe Protector." Before the installation of the NMR Pipe Protector, a white filter was attached to the kitchen sink water supply faucet for seven days, during which the filter became discolored brown due to red rust generated in the water supply pipes. After dissolving the captured iron content with purified water and measuring the iron concentration, it was found that the iron level in the water was 21 mg/l, indicating that the red rust corrosion in the pipes was quite advanced. One month after installation, a white filter was attached under the same conditions as before, and it was confirmed that the filter's discoloration had reduced to light brown, with the iron concentration decreasing significantly to 5.8 mg/l. Additionally, six months after installation, a white filter was again attached under the same conditions, and it was confirmed that the filter's discoloration had nearly returned to white, with the iron concentration further decreasing significantly to 0.75 mg/l. From this, it can be concluded that just one month after the installation of the NMR Pipe Protector, the progression of red rust was completely halted, and at the same time, the surface of the red rust in the water supply pipes transformed into a non-soluble black rust, resulting in a reduction of iron leaching into the water and a decrease in filter discoloration.

[NMR Pipe Protector Verification Results] Nursing Facility #HO

The red rust inside the water supply pipe has transformed into hard crystalline black rust with a volume reduction of 1/10! The rehabilitation of the piping due to the black rust formation from red rust has been confirmed!

This nursing facility had experienced significant deterioration due to red rust in the water supply and hot water supply pipes. Therefore, when the building was 25 years old, a red rust prevention device called the "NMR Pipe Protector" was installed in the water supply pipe on the secondary side of the rooftop water tank and in the hot water supply pipe on the secondary side of the boiler. Before the installation of the NMR Pipe Protector, the iron ion concentration in the water supply was 2.27 mg/l, and the color degree was 20, indicating severe deterioration due to red rust in the pipes. Four weeks after the installation of the NMR Pipe Protector, the iron ion concentration in the water dropped to 0.46 mg/l, and the color degree improved to 5, showing a significant improvement in water quality. Furthermore, the water quality test results 12 weeks after installation showed that the iron ion concentration was 0.03 mg/l, and the color degree was less than 0.5. The red rust in the water supply pipe had transformed into hard crystalline black rust with a volume reduction of 1/10, stopping the leaching of red rust into the water. The rehabilitation of the pipes due to the black rust formation was confirmed. This demonstrated that if the use of the NMR Pipe Protector continues, both the water supply and hot water supply pipes can be extended to the lifespan of the building.

[NMR Pipe Protector Verification Results] Fukuoka Prefecture Condominium

After 16 years of installation, the effectiveness verification shows a reduction in red rust blockage rate from 50.7% to 41.2%, an improvement of 18.7%! This demonstrates the effectiveness of red rust prevention and pipe lifespan extension.

A follow-up survey was conducted in a condominium in Fukuoka Prefecture, 16 years after the installation of the NMR pipe protector. Before installation, the joints of the water supply pipes in Rooms A and B were inspected with a fiberscope, revealing red rust blockage rates of 50.7% and 78.2%, respectively, indicating significant progression of red rust blockage and the need for early intervention. Consequently, the NMR pipe protector was installed in the water supply piping. One year after installation, a follow-up survey was conducted under the same conditions as before installation, and the red rust blockage rates for Rooms A and B were as follows: [One Year After Installation] Room A: 50.7% → 48% [5.3%] reduction improvement Room B: 78.2% → 74.1% [5.2%] reduction improvement [Sixteen Years After Installation] Room A: 50.7% → 41.2% [18.7%] reduction improvement Room B: 78.2% → 68.4% [12.5%] reduction improvement From the above reduction improvement rates in red rust blockage, it was demonstrated that the NMR pipe protector completely prevented the occurrence of new red rust and that the red rust blockage transformed into black rust with a volume reduction to one-tenth. Additionally, it was proven that as long as this condominium remains standing for another 20 or 30 years, pipe replacement will not be necessary.

[NMR Pipe Protector Verification Results] Moseley Hospital (NHS)

Prevent red rust and leaks in the hot water piping of Moseley Hospital!

Moseley Hospital has two independent hot water systems: one connected to the storage tank and the other connected to the hot water header, with galvanized steel pipes used in the hot water piping. As a result, NMR pipe protectors were installed in the storage tank piping and the hot water header piping to prevent red rust corrosion and leaks in both hot water systems. Water samples were taken from the hot water piping at five locations, and the average iron content in the water was calculated. Before the installation of the NMR pipe protectors, the average value was 13.824 mg/l. After 15 weeks of installation, it decreased to 1.3882 mg/l; after 31 weeks, it further decreased to 0.4762 mg/l; and after 49 weeks, it reached 0.3428 mg/l, showing a significant reduction. This result demonstrated that the NMR pipe protectors prevented the formation of new red rust within the pipes and reduced existing red rust to black rust, which is insoluble in water and has a volume that is one-tenth of that of red rust. It has been proven that by continuing to install NMR pipe protectors, the hot water piping will transform 100% of the red rust within the pipes into black rust, thereby extending the lifespan of the building.

[Case Study of Pipe Protector] St. Thomas Hospital and Coil-Type Electromagnetic Device

[Case Study of Pipe Protector] St. Thomas Hospital and Coil-Type Electromagnetic Device

Unexpected Facts about Coil-Type Electromagnetic Devices and Examples of Pipe Protectors and Non-Scalers

1. Regarding the effectiveness of rust prevention (anti-corrosion) In the UK, coil-type electromagnetic devices are primarily used as a measure against calcium scale, and their effectiveness in preventing red rust has not been recognized. In fact, at St. Thomas' Hospital, famous for Florence Nightingale and where the NHS headquarters is located, this device was introduced into the hot water piping, but it showed no anti-corrosion effect, and red rust deterioration was progressing. As a result, an NMR pipe protector was installed in 2005. Before installation, the hot water contained a high concentration of iron ions, but after one month, the concentration significantly decreased, halting the progression of red rust deterioration and confirming a change to insoluble black rust. Although coil-type electromagnetic devices are also sold domestically, please be aware that their effectiveness against red rust has not been confirmed. 2. Regarding the effectiveness of calcium scale prevention Coil-type electromagnetic devices are also sold domestically as scale prevention devices, but in a major food factory where they were introduced, they failed to prevent scale adhesion within the pumps. As a result, a non-scaler was adopted, completely preventing adhesion. Disassembly and cleaning, which were previously required every few months, are no longer necessary. If you have not achieved results with coil-type devices, please consider introducing a non-scaler.

NMR Pipe Protector that Promotes the Growth of Tomatoes and Strawberries in Agriculture

NMR Pipe Protector that Promotes the Growth of Tomatoes and Strawberries in Agriculture

The rust prevention effect of the NMR pipe protector is due to the action of small clusters of water, which has also been proven to promote the growth of tomatoes and strawberries.

The pipe rust prevention device "NMR Pipe Protector" was featured on TV Tokyo's economic information program "World Business Satellite (WBS)." The rust prevention effect of the water from the NMR Pipe Protector has small clusters, which promotes the growth of vegetables, leading to verification in the agricultural field. At "Mitsu Village" in Himeji City, Hyogo Prefecture, NMR Pipe Protectors are installed in the pipes that supply water to the 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 larger. From previous verifications, it has been found that growing tomatoes with water from the supply pipe 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.

To prevent pipe rust, the famous C University library has introduced NMR pipe protectors.

To prevent pipe rust, the famous C University library has introduced NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" is simply installed on the outside of the air conditioning chilled and hot water pipes, converting red rust to black rust throughout the entire piping system for long-term durability.

In the year 2000, 13 years after its completion, it was discovered that there was leakage due to red rust deterioration in part of the chilled and hot water piping of C University Library. The circulating water was mixed with red rust, and the deterioration of the piping had progressed significantly. As a rust prevention measure inside 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, a red rust prevention device called the "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 service interruption, construction could proceed while the building was in use, eliminating the need for the library and surrounding facilities to close. After installation at C University Library, the rust prevention effect in the chilled and hot water piping was confirmed by an increase in the amount of black rust among the red rust. After the introduction of the NMR Pipe Protector, the piping was removed, and quantitative proof of the conversion of red rust to black rust was established through mass analysis of rust samples.

Pipe rust prevention, Kumamoto Red Cross Hospital has introduced NMR pipe protectors.

The Kumamoto Red Cross Hospital, which strengthened the piping joints with the black rust conversion effect of the red rust prevention device "NMR Pipe Protector," completely prevented water leaks during the Kumamoto earthquake.

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 cannot be ignored is the "deterioration of pipes due to red rust." One of the issues caused by the deterioration of the air conditioning hot and cold water pipes is "leakage." In advanced medical facilities, 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 pipe deterioration, and its effectiveness was recognized, leading to its implementation throughout the entire facility. A water quality survey conducted before the installation of the NMR Pipe Protector revealed that the iron content due to red rust in the hospital's air conditioning hot water was 12.3 mg per liter, indicating significant red rust presence. However, just two weeks after the installation of the NMR Pipe Protector, this level 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.*

Pipe anti-corrosion, Lions Mansion Koshigaya North has introduced NMR pipe protectors.

Pipe anti-corrosion, Lions Mansion Koshigaya North has introduced NMR pipe protectors.

The installation of the rust prevention device "NMR Pipe Protector" on the water supply pipes has been confirmed through long-term verification that the black rust transformation of red rust inside the pipes progresses every year, improving the condition of the piping.

The "Lions Mansion Koshigaya North" in Koshigaya City, Saitama Prefecture, introduced the NMR Pipe Protector in November 2010, successfully reducing 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 rate of red rust blockage at the dissimilar metal joints, where red rust deterioration progresses the most, was continuously inspected, confirming that the rate of red rust blockage decreased over time. This indicates that the red rust is gradually transforming into black rust, which is one-tenth of its original 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 projects such as converting lighting fixtures to LED. In addition to the LED conversion of lighting, 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 surplus 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 noted, indicating that the transformation to black rust is progressing.

Preventing the reduction of residual salt concentration by converting red rust in the main water supply pipe (distribution pipe) to black rust.

Preventing the reduction of residual salt concentration by converting red rust in the main water supply pipe (distribution pipe) to black rust.

The red rust prevention device "NMR Pipe Protector" converts red rust inside water pipes to black rust and prevents the decrease of chlorine (residual chlorine) concentration for disinfection.

The NMR Pipe Protector has been widely adopted as a device for preventing red rust in piping and extending the lifespan of pipes, and it has recently gained attention in water distribution pipes of water supply agencies. At the Japan Water Works Association's water research presentation held in 2013, the Yokohama City Water Bureau published a paper reporting 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 News. The initial verification confirmed the reduction of iron ion levels in the water and the increase in residual chlorine concentration before and after installation in the water supply pipe within the Tsurumi water reservoir's associated housing. 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 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 (distribution pipes). *For more details, please refer to the PDF or contact us.*

To prevent pipe rust, a famous bookstore building has introduced NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" prevents red rust deterioration inside air conditioning pipes, ensuring the long-term longevity of the pipes and proactively preventing asbestos issues.

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 replacing the piping, 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 transformation 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.*

Pipe rust prevention, Mansion Palace Tsurumi has introduced NMR Pipe Protectors.

Pipe rust prevention, Mansion Palace Tsurumi has introduced NMR Pipe Protectors.

Rust prevention device "NMR Pipe Protector" demonstrates rust prevention effectiveness even when introduced to a 39-year-old condominium!

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 completion. 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 insufficient reserve funds, it was difficult for the management association to proceed with the pipe replacement. The management association approved the introduction of the NMR Pipe Protector at the general meeting because it came with a guarantee that stated, "If it does not work, we will refund you." To objectively evaluate the red rust prevention effect of the red rust prevention device "NMR Pipe Protector," quantitative effect measurement is conducted. 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 investigation of the red rust blockage rate using an endoscope 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. The NMR Pipe Protector demonstrated its rust prevention effectiveness even in piping that had not undergone maintenance for 39 years since completion. *For more details, please refer to the PDF or feel free to contact us.*

Pipe rust prevention, Legend Hotel Saigon introduces NMR pipe protectors.

Pipe rust prevention, Legend Hotel Saigon introduces NMR pipe protectors.

Terrible red water becomes clear! The "NMR Pipe Protector," a device that eliminates red water caused by rust in pipes in a short period.

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, leaving guests unable to even take showers. The water in Vietnam contains a high level of sulfate components, which reacts with galvanized steel pipes (SGP), making it very prone to red rust formation. 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 taps in the hotel. However, about a month and a half later, after conducting water quality checks in the sinks, baths, and toilets of ten guest rooms on the 14th to 17th floors, it was found that the water supply in almost all rooms 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 sulfate content that easily corrodes water supply pipes, the conversion of red rust to black rust could be achieved, exhibiting a high level of rust prevention effectiveness. *For more details, please refer to the PDF document or feel free to contact us.*

To prevent pipe rust, Tokyo University of Science has introduced the NMR Pipe Protector.

To prevent pipe rust, Tokyo University of Science has introduced the NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" prevents the deterioration of piping due to red rust, resulting in significant cost savings.

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 of the red rust. 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.

To prevent red rust in piping, Nihon University College of Engineering has introduced the NMR Pipe Protector.

To prevent red rust in piping, Nihon University College of Engineering has introduced the NMR Pipe Protector.

The red rust prevention device "NMR Pipe Protector" achieves rust prevention and reinforcement of piping through the black rust transformation of red rust! It significantly reduces maintenance costs for water supply pipes.

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 from the taps on holidays and the following days. To reduce the future piping renewal costs by 1/5 to 1/10, a red rust prevention device called "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). Originally, the iron content was at 7.8 mg/L, exceeding the water quality standard value of the Water Supply Act (0.3 mg/L), indicating a very serious progression of red rust. However, after installation, it was significantly below that standard value, 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 materials or feel free to contact us.
