[Special Feature on Preventing Red Rust in Piping] Preventing Water Leakage in Hot Water Pipes at Whittington Hospital, UK

[Special Feature on Preventing Red Rust in Piping] Preventing Water Leakage in Hot Water Pipes at Whittington Hospital, UK

The red rust in the hot water piping of Whittington Hospital in the UK has been converted to black rust, demonstrating the anti-corrosion and prolonging effects on the piping.

Whittington Hospital (affiliated with the NHS) was built in the 1860s, and as a result, the building has deteriorated, with the hot water piping having not been updated for approximately 30 to 40 years since the last renovation. If this situation continues, the risk of clogs and leaks due to corrosion in the hot water pipes is high, so we decided to introduce the red rust prevention device "NMR Pipe Protector." As a result of installing the NMR Pipe Protector, the occurrence of new red rust has been completely prevented, and there have been no instances of red water, proving that the hot water piping has been significantly extended in its lifespan. Additionally, the interior of the piping is protected from black rust by the NMR Pipe Protector, preventing the progression of red rust corrosion, allowing the piping to be used until the building's lifespan as long as the NMR Pipe Protector is installed. [Installation Results] ■ Piping can be used until the building's lifespan ■ Significant cost reductions achieved ■ No need for water outages * Customer testimonials (recommendation letters) and other PDF materials are 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 "NMR Pipe Protector" is a device for preventing red rust in pipes.

The piping rust prevention 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 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 items 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 NMR pipe protectors.

Preventing red rust in the air conditioning pipes of the BBC and extending the lifespan of the pipes by preventing leaks with the red rust prevention device "NMR Pipe Protector."

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.*

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

The red rust inside the cast iron water distribution 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 water supply district of Huong Canh in Binh Phuoc Province, Vietnam, cast iron pipes (150A) have been in use for 15 years, leading to the progression of red rust corrosion inside the pipes, resulting in the frequent occurrence of red water. To address this red water issue, a red rust prevention device called "NMR Pipe Protector" was installed at the base of the cast iron water supply pipe (150A). Before installation, the water color and the amount of red rust at the sampling points were as follows: the northern sampling point, located 500 meters north of the installation site, had a light brown color and 7.0 mg/l of red rust; the western sampling point, located 300 meters west, had a brown color and 8.0 mg/l; and the southern sampling point, located 600 meters south, had a dark brown color and 23 mg/l. Two weeks after installation, the northern sampling point showed a lighter color and a reduction in red rust to 4.6 mg/l. The western point also 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 dissimilar metals in the water supply pipes, 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 to a brownish color due to the 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 concentration in the water was 21 mg/l, indicating that the red rust corrosion in the pipes was very advanced. One month after installation, a white filter was attached under the same conditions as before, and it was confirmed that the discoloration of the filter had reduced to light brown, with the iron concentration decreasing significantly to 5.8 mg/l. Furthermore, 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 reduced 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] Palace of Westminster

[NMR Pipe Protector Verification Results] Palace of Westminster

The new red rust formation occurring inside the pipes has completely stopped, and the existing red rust has turned into black rust!

The Palace of Westminster is currently used as the UK Parliament and is one of the most famous buildings in the UK. It is located on the banks of the River Thames in central London and is a structure over 150 years old that was rebuilt around 1860. In one of the multiple buildings (the Guard Room), the air conditioning hot water piping was severely corroded due to red rust. To prevent the occurrence of new red rust in this piping system, one "NMR Pipe Protector PT-75DS" was installed in the air conditioning hot water piping on the secondary side of the boiler. The iron content in the water before the installation of the NMR Pipe Protector was 3.9 mg/l, but it decreased to 2.38 mg/l 34 days after installation. It was confirmed that 59 days after installation, the iron content in the water had decreased to 1.48 mg/l, which is less than half of the pre-installation value. This result demonstrated that the occurrence of new red rust in the piping was completely stopped, and the existing red rust was converted to black rust, which does not dissolve in water and protects the piping with a corrosion-resistant layer. With the installation of the NMR Pipe Protector, the air conditioning hot water piping can now be used semi-permanently as long as the building remains standing.

The red rust in 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, we installed the red rust prevention device "NMR Pipe Protector" in the water supply pipe on the secondary side of the rooftop water tank and in the hot water 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 was reduced 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 in the water 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 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 from red rust was confirmed. As a result, it has been demonstrated that by continuing to use the NMR Pipe Protector, both the water supply and hot water supply pipes can be extended to last until the building's lifespan.

The NMR pipe protector sheds light on the issue of marine pollution caused by plastic waste!

Approaching global environmental issues! "NMR Pipe Protector" for preventing red rust inside pipes.

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 marine pollution caused by plastic waste, which has become a global issue, can be significantly improved by installing the 'NMR Pipe Protector,' developed with Japan's advanced technological capabilities, in urban areas of developing countries. *For more details, please refer to the PDF document or feel free to contact us.

Agricultural success: NMR pipe protector that promotes the growth of tomatoes and strawberries.

Agricultural success: NMR pipe protector that promotes the growth of tomatoes and strawberries.

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 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.

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, 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.

To prevent pipe red rust, Kumamoto Red Cross Hospital has introduced NMR pipe protectors.

To prevent pipe red rust, Kumamoto Red Cross Hospital has introduced NMR pipe protectors.

The Kumamoto Red Cross Hospital, which strengthened the piping joints with the black rust 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 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.*

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

Prevent 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 in 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 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.*

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

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 in air conditioning pipes, ensuring long-term extension 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 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.*

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 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.*

Terrible red water becomes clear! The "NMR Pipe Protector," a device that eliminates red water caused by red 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, 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.*

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. 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.

The red rust prevention device "NMR Pipe Protector" achieves rust prevention and strengthening of pipes 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 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.*

[NMR Pipe Protector Verification Results] City, University of London

Complete protection of piping from red rust corrosion through black rust formation! A case that has been usable for over 40 years!

London City University is one of the famous universities located in North London. It uses SGP for its air conditioning hot water piping, and the pipes in the over 40-year-old building were experiencing red rust corrosion. To completely protect the piping from red rust corrosion, "NMR Pipe Protector" was installed. Before installation, the iron content in the water due to red rust was 3.407 mg/l, but two weeks after installation, the iron content decreased to 0.084 mg/l. This demonstrated that our product prevented the occurrence of new red rust in the piping and reduced existing red rust to inert black rust. 【Introduction Overview】 ■ Building Name: London City University ■ Location: London, UK ■ Building Overview: 47 years old, university ■ Installation Date: June 13, 2013 ■ Installed Piping/Quantity: Air conditioning hot water piping/PT-200DS × 1 unit *For more details, please refer to the PDF document or feel free to contact us.
