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.

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

Proving the rust prevention and prolongation effect of the piping by converting red rust to black rust in the hot water supply piping of Whittington Hospital in the UK.

Whittington Hospital (affiliated with the NHS) was built in the 1860s, and the building has been deteriorating, with the hot water piping having not been updated for about 30 to 40 years since the last renovation. As it stood, the risk of clogs and leaks due to corrosion in the hot water pipes was high, leading to the decision to introduce the red rust prevention device, the "NMR Pipe Protector." As a result of implementing 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. As long as the NMR Pipe Protector is installed, the piping can be used for the lifespan of the building. [Installation Results] ■ Piping can be used until the lifespan of the building ■ 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.

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.

[Disaster Prevention] Easily prevent the risk of leaks from old pipes left unattended for over 20 years!

Old piping is likely to suddenly cause multiple leaks even with a small earthquake. Large-scale replacement work for the piping can lead to significant damage... What measures can be taken now?

Are you aware? The lifespan of piping is said to be about 20 years. At first glance, piping is often overlooked because it is not visible from the outside, but like buildings, it continues to deteriorate over time. Furthermore, in recent years, the majority of equipment damage caused by earthquakes has been due to "piping within buildings," such as air conditioning systems. Sudden leaks caused by earthquakes can occur in multiple locations and result in significant damage... Once a leak occurs, it requires a large-scale construction cost for "piping replacement (piping renewal)." To prevent accidents before they happen, we recommend the NMR Pipe Protector! ★ Just by installing it on the outside of the piping, it extends the lifespan of the piping and strengthens the interior! ★ = Maximum Benefits = - The initial cost is less than one-tenth of that for piping renewal - Running costs and maintenance are "zero" - High safety that is also implemented in food factories and hospitals Please feel free to contact us first.

[NMR Pipe Protector Verification Results] Palace of Westminster

The new occurrence of red rust inside the piping 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 building over 150 years old that was rebuilt around 1860. In one of the several 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 had completely stopped, and the existing red rust had turned into 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.

[NMR Pipe Protector Verification Results] Kawanishi City Kushi Elementary School

Proven rust prevention effect in water quality test one week after installation!

This property is a 29-year-old building that originally used galvanized steel pipes (SGP) for its plumbing at the time of completion, but over the years, it has been updated to use vinyl-lined steel pipes (VLP). However, due to the building's structure, the plumbing inside the framework remained galvanized steel pipes (SGP), which led to the occurrence of red water due to corrosion. To address the red water issue in the water supply pipes and to protect and extend the life of the plumbing, NMR Pipe Protectors were installed. The NMR Pipe Protector costs less than one-tenth of traditional plumbing renovation work and can rehabilitate the pipes by converting red rust into black rust without allowing it to flow out. In water quality tests conducted before the installation of the NMR Pipe Protector, the iron ion concentration was 0.3 mg/l. However, about five weeks after the installation of the NMR Pipe Protector, this concentration dropped to 0.01 mg/l, which is one-thirtieth of the original level, effectively resolving the red water issue. Additionally, an endoscopic examination revealed that the rate of blockage due to red rust in the pipes improved by more than 10% after one year and three months. These results confirm that the rust prevention effect of the NMR Pipe Protector and the rehabilitation effect of converting red rust to black rust continue to be effective.

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.

Pipe anti-corrosion: Yokohama City Waterworks Bureau conducts effectiveness verification of NMR pipe protectors (2)

The Yokohama City Waterworks Bureau has verified the effectiveness of the "NMR Pipe Protector" in preventing the decrease of residual chlorine concentration in water distribution pipes.

The Yokohama City Waterworks Bureau confirmed an increase in residual chlorine concentration to prevent red rust and the associated reduction of disinfectant chlorine in the water supply pipe at the Tsurumi public office. Therefore, starting from November 5, 2012, a demonstration test was conducted using the water distribution pipe (100A) in the Hazawa area to prevent the decrease in residual chlorine concentration. During six measurements conducted from September 26 to October 30, before the installation of the NMR pipe protector, the residual chlorine concentration at the planned installation site (Point A) averaged 0.55 mg/L (with Point A's residual chlorine concentration set at 100%), while 50 meters downstream (Point B) averaged 0.41 mg/L (a reduction rate of 25.45%), and at the farthest point, 125 meters away (Point C), it averaged 0.23 mg/L (a reduction rate of 58.18%), indicating a decrease due to the red rust occurring in the piping. Subsequently, on November 5, the NMR pipe protector was installed, and after more than three months, during three measurements from February 19 to March 22, the residual chlorine concentration at the installation site (Point A) averaged 0.61 mg/L, while at 50 meters downstream (Point B) the average for the same three measurements was 0.61 mg/L (a reduction rate of 0%), showing that the decrease was mostly prevented. Even at the farthest point, 125 meters away (Point C), the average for the same three measurements was 0.55 mg/L (a reduction rate of 9.84%), significantly improving the reduction rate.
