[NMR Pipe Protector Verification Results] Palace of Westminster

[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] Ministry of Land, Infrastructure, Transport and Tourism, National Graduate Institute for Policy Studies

The iron concentration (mg/l) two months after installation is 0.22! We will introduce a case that demonstrates the rust prevention effect!

We would like to introduce the verification results conducted by our company. Due to the deterioration of red rust in the water supply pipes, we installed the "NMR Pipe Protector." The iron content before installation was 1.1 mg/l, but it decreased to 0.22 mg/l within two months of installation, proving the rust prevention effect. 【Introduction Overview】 ■ Location: Kodaira City, Tokyo ■ Installation Date: December 12, 2012 *For more details, please refer to the PDF document or feel free to contact us.

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

[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.

[Case Study of Dipole] Koi Castle Development Co., Ltd.

[Case Study of Dipole] Koi Castle Development Co., Ltd.

Affordable solutions for red rust prevention in building plumbing! Introducing case studies of Dipole.

This is a case study of Koijokaihatsu Co., Ltd., which has been engaged in the real estate business in Hiroshima Prefecture for 40 years. We installed a "DIPOLE" in a building that includes three tenant shops, an office, and a residence, all of which are 18 years old. Previously, when red rust appeared in the pipes, we addressed it by using a water purifier from another company. The estimate for treating the red rust in the pipes was 820,000 yen, but by installing the DIPOLE, the red rust changed to black rust, allowing us to manage the piping issues at a much lower cost. We received a commitment to focus on contributing to environmental improvement in Hiroshima with DIPOLE and to expand our business in the future. [Case Study] ■ Model Used: DIPOLE 20A *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 (2)

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.

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.
