Reduce the maintenance costs for air conditioning chilled and hot water piping in libraries, museums, etc., to one-tenth or less.

NMR Pipe Protector, a piping rehabilitation device that prevents leaks by preventing red rust in the chilled and hot water piping of cultural centers, libraries, and museums, reducing maintenance costs to less than one-tenth.

Art museums, museums, cultural centers, libraries, and other places frequently visited by the general public and tourists use energy-efficient warm-type central air conditioning. The chilled water piping for this air conditioning is made of galvanized steel pipes (SGP pipes), which, after more than 20 years of construction, undergoes red rust deterioration. When the threads at the piping joints fall off due to red rust deterioration, leaks can occur from these weakened areas during earthquakes and other events. Additionally, red rust deterioration inside the pipes can lead to problems such as reduced heating and cooling efficiency and premature failure of the heat source equipment. The solution to this issue of red rust deterioration inside the pipes is the pipe rehabilitation device NMR Pipe Protector.

It has also been adopted by City, University of London!

Extending the lifespan of piping! Case study of the "NMR Pipe Protector" at City, University of London.

City, University of London is one of the famous universities located in North London, and it uses SGP for its air conditioning hot water piping. The piping in buildings over 40 years old was experiencing red rust corrosion. To completely protect the piping from red rust corrosion, NMR pipe protectors were 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 the NMR pipe protectors prevented the occurrence of new red rust in the piping and reduced existing red rust to inert black rust. With the conversion of red rust to black rust, the piping was completely protected from red rust corrosion, allowing the air conditioning hot water piping to be usable for over 40 years. ▼For more details, please see the related link▼

Prevention of red rust and water leakage in the hot water piping of the Mandarin Oriental Hotel in the UK.

Case study of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel hot water piping.

The Mandarin Oriental Hotel is an elegant five-star hotel located in London. Due to the occurrence of red rust corrosion issues and concerns about leaks in the hot water supply piping (SGP) of the Mandarin Oriental Hotel, two units of the red rust prevention and leak prevention device "NMR Pipe Protector" PT-75DS were installed at the header section of the circulating hot water piping. Before the installation of the NMR Pipe Protector, the iron content in the water within the hot water piping was 13.35 mg/l, indicating significant progression of red rust corrosion. Four weeks after installation, the iron content in the hot water within the piping decreased to 0.0043 mg/l, and further decreased to less than 0.004 mg/l five weeks after installation. This demonstrated that the progression of red rust within the hot water piping was completely halted by the NMR Pipe Protector, and the existing red rust transformed into insoluble black rust in a volume reduced to one-tenth. It has been verified that if the Mandarin Oriental Hotel continues to use the NMR Pipe Protector, all red rust in the hot water piping will change to black rust, and the cost will be less than one-fifth of the cost of pipe replacement work, allowing the piping to be extended for the lifespan of the building. Naturally, leaks will be completely prevented thereafter.

Solving the red rust and leakage issues in the water supply and hot water piping at the Marriott Hotel in the UK.

Case studies of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel water supply and hot water piping.

The Bournemouth Highcliff Marriott Hotel, part of the world's largest five-star hotel chain, the Marriott Group, was built in 1878 and has 160 rooms. Due to the use of galvanized steel pipes for hot water and water supply plumbing, very high iron levels were detected before the installation of the NMR pipe protector, with 6 mg/l from the hot water pipes and 3.46 mg/l from the water supply pipes. The deterioration of red rust in the pipes, including red water, was serious, raising concerns about future leaks. To eliminate red water from the water supply and hot water pipes, prevent red rust deterioration, and extend the life of the plumbing, NMR pipe protectors were installed in both the water supply and hot water pipes. Thirteen days after installation, the hot water and water supply samples taken first thing in the morning (stagnant water from overnight) were both clear, and the iron levels in the water had dropped to 0.007 mg/l, completely eliminating red water. The reduction in iron levels prevented the formation of new red rust, and it was demonstrated that the existing red rust in the pipes had transformed into a non-soluble volume of 1/10 of inert black rust. As a result, the formation of new red rust in the pipes was prevented, and the transformation of existing red rust into black rust confirmed the effectiveness of the NMR pipe protector in preventing red rust and extending the life of the plumbing.

Solving the red rust and leakage issues of the air conditioning hot and cold water piping at the Millennium Hotel in the UK.

Case study of introducing NMR pipe protectors for preventing red rust and extending the lifespan of hotel water supply piping.

The Millennium Hotel London Mayfair is a historic building located in the heart of London, overlooking Grosvenor Square, which was once the residence of the Duchess of Kendal in the 18th century. To address issues of red rust and leakage in the air conditioning hot water piping, the "NMR Pipe Protector," a rust prevention and pipe longevity device that does not require pipe removal or water shutdown during installation, was installed. Before the installation of the NMR Pipe Protector, the iron content in the air conditioning hot water piping due to red rust was very high at 15.7 mg/l, indicating significant red rust deterioration and concerns about leakage. To prevent this red rust and leakage, the "NMR Pipe Protector" was introduced. Six weeks after the installation of the NMR Pipe Protector, the test results of the air conditioning hot water showed that the iron content in the water had significantly decreased to 0.157 mg/l, completely preventing new red rust in the air conditioning hot and cold water piping, and it was proven that the existing red rust had transformed into black rust, which is insoluble in water and has a volume one-tenth that of red rust. If the NMR Pipe Protector continues to be used, it has been demonstrated that all red rust in the piping will transform into black rust, preventing external corrosion and leakage, thereby extending the lifespan of the building.

[NMR Pipe Protector Verification Results] Major Automobile Manufacturer Factory in Fukuoka Prefecture

The amount of black rust increased significantly from 4% to 43.6%! A case where line stoppage was completely prevented.

In August 1998, an "NMR Pipe Protector" was installed in the cooling water circulation piping of the welding robot cooling line located within a major automobile manufacturer's factory in Fukuoka Prefecture to prevent red rust scale. Before installation, red rust from the cooling water piping would leach out, entering the narrow cooling tubes of the body welding robots, causing blockages that resulted in the welding robots stopping, which took over 15 minutes to recover. Nine months after installation, the cooling water piping was inspected, and compared to the amount of black rust in the red rust before installation, it significantly increased from 4% to 43.6%. Additionally, line stoppages were completely prevented. [Challenges] - Red rust leaching from the internal cooling water piping - Entry into the narrow cooling tubes of the body welding robots, causing blockages - Recovery from welding robot stoppages taking over 15 minutes - Damage costs exceeding 6 million yen per incident *For more details, please refer to the PDF document or feel free to contact us.*

[NMR Pipe Protector Verification Results] St. Ignatius Church

A case where it was confirmed that the red rust inside the piping is in a good condition and not dissolving in water!

St. Ignatius Church, also known as the Catholic Kojimachi Church, is a historic church adjacent to Sophia University that has existed since before the war. Four years ago, due to the deterioration of red rust in the air conditioning chilled and hot water piping, we conducted an evaluation of the rust prevention effect of the "NMR Pipe Protector," a device designed to prevent red rust within the piping. Before the installation of the NMR Pipe Protector, we collected samples of the circulating chilled and hot water, which showed a brownish color. Water quality tests revealed a total iron concentration of 240 mg/l, indicating significant progression of red rust corrosion within the piping. After installing the NMR Pipe Protector, we conducted another water sampling test two weeks later, and the water color had become nearly transparent, with the total iron concentration due to red rust reduced to 2.7 mg/l, a substantial decrease. At the same time that the progression of red rust had stopped, the surface red rust within the chilled and hot water piping and the red rust in the water transformed into a non-soluble black rust, confirming the rust prevention effect of the NMR Pipe Protector within the chilled and hot water piping. This result was featured in an article published on July 18, 2018, in issue 2737 of "Air Conditioning Times," which reported on the verification of the rust prevention effect of the NMR Pipe Protector at St. Ignatius Church.
