The effects continue 15 years after the introduction of the NMR pipe protector.

The effects continue 15 years after the introduction of the NMR pipe protector.

Verification of the red rust prevention effect of apartment water supply pipes: Introduction of a case study after more than 15 years since the implementation of the red rust prevention device "NMR Pipe Protector" inside the piping!

In August 2001, we introduced the "NMR Pipe Protector" to the Co-op Nomura Minami Ishikiri condominium in Wakabayashi Ward, Sendai City, Miyagi Prefecture. After 15 years of implementation, an investigation into the deterioration of the piping was conducted. The investigation involved removing the water supply pipes on the secondary side of the elevated water tank and inside the residences, as well as the drainage pipes. It was evaluated that "there was almost no red rust due to internal deterioration of the water supply pipes, and there were no blockages; it was confirmed that the surface had turned black due to rust, and pipe rehabilitation had been carried out." The condominium's maintenance director stated during an interview, "Not only the water supply pipes but also the drainage pipes have been extended in their lifespan, and there are no plans for updates in the long-term repair plan." He added, "As the building ages, it will only become more financially challenging in the future, so the benefits of not having to update the water supply pipes are immeasurable." *For more details, please refer to the PDF document or feel free to contact us.

NMR pipe protector adopted by Buckingham Palace in the UK for preventing pipe rust.

NMR pipe protector adopted by Buckingham Palace in the UK for preventing pipe rust.

The NMR pipe protector has been proven effective in preventing red rust on the air conditioning and hot water pipes at Buckingham Palace and has been adopted.

On January 12, 2007, in one of the six pump rooms located within Buckingham Palace, only one pump room supplying Her Majesty's room had the 'NMR Pipe Protector' installed for the air conditioning hot water piping and the hot water supply piping. Before the installation of the NMR Pipe Protector, the iron ion concentration in the circulating hot water within the air conditioning hot water piping for Her Majesty's room was measured at 16.6 mg/L, indicating a high iron ion level and a significant presence of red rust within the piping. Subsequently, 24 days after the installation of the NMR Pipe Protector, the iron content in the hot water within the air conditioning hot water piping decreased to 0.455 mg/L. The piping was completely protected from red rust by the NMR Pipe Protector, and the lifespan of the piping was extended, which has been greatly appreciated by those associated with Buckingham Palace for security reasons. *Customer feedback (customer testimonials) and other PDF materials are available for free! *Please feel free to contact us first.

How can the lifespan of water supply pipes and air conditioning chilled and hot water pipes be extended to match the lifespan of the building?

How can the lifespan of water supply pipes and air conditioning chilled and hot water pipes be extended to match the lifespan of the building?

It is possible to convert red rust to black rust without direct contact with the water inside the pipes, preventing red rust and leaks! The red rust prevention device for pipes, "NMR Pipe Protector."

To extend the lifespan of existing piping to match the lifespan of the building, if the red rust occurring inside the pipes can be converted to black rust without flushing it away, the lifespan of the pipes can be prolonged to that of the building. When extending the lifespan of pipes, methods such as pipe cleaning or sandblasting to remove red rust can damage the interior of the pipes, reducing their strength. With our internal red rust prevention device, the 'NMR Pipe Protector,' red rust can be converted to black rust without directly contacting the water inside the pipes. By utilizing NMR (nuclear magnetic resonance), it is possible to prevent the deterioration of red rust inside the pipes and even rehabilitate and strengthen the pipes. It is suitable for preventing red rust in water supply pipes (vinyl-lined steel pipes) and air conditioning hot and cold water pipes (galvanized steel pipes), as well as for the rehabilitation and strengthening of pipes. *For more details, please refer to the PDF materials or feel free to contact us.

Pipe rust prevention, the British Museum has introduced NMR pipe protectors.

Pipe rust prevention, the British Museum has introduced NMR pipe protectors.

The British Museum prevents red rust in the air conditioning hot water pipes with the anti-rust device "NMR Pipe Protector" and verifies its pipe longevity effect.

The British Museum has undergone multiple renovations over the years, but the building is over 264 years old. It is an important museum that needs to continue to exist in the future, but the issue of building deterioration cannot be avoided. One of those issues was the concern of leaks due to the deterioration of the heating hot water piping from red rust. In March 2016, we verified whether the 'NMR Pipe Protector' is truly an effective measure against red rust in piping by installing one unit on the air conditioning hot water piping and conducting iron content tests in the same circulating hot water before and after installation. Before the installation of the NMR Pipe Protector, the iron content in the water was very high due to red rust. Three weeks after installation, it measured 3.44 mg/L, and five weeks after installation, it dropped significantly to 0.2 mg/L, demonstrating the effectiveness of red rust prevention as it matched the drinking water standard of 0.2 mg/L. It has been recognized that if the NMR Pipe Protector continues to be used, the lifespan of the piping can be extended to match the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.*

To prevent pipe rust, the London City Hall has introduced NMR pipe protectors.

To prevent pipe rust, the London City Hall has introduced NMR pipe protectors.

The London City Hall used the rust prevention device "NMR Pipe Protector" to convert red rust in the hot water supply pipes to black rust, verifying the effectiveness of preventing red rust and extending the lifespan of the pipes.

The "NMR Pipe Protector" has garnered attention worldwide for its ability to solve the problem of red rust. Every morning, red water would come out from the hot water pipes in Guildhall, London. When we measured the iron content in the water, it was found to be 6.36 mg per liter, indicating significant red rust, which is considerably higher than the water quality standard of 0.2 mg per liter set by UK water regulations. Three weeks after installing the NMR Pipe Protector, the iron content in the water was measured at 0.015 mg per liter. This is a reduction to 1/400 of the iron content before installation, and further measurements taken seven weeks after installation showed a decrease to 0.007 mg per liter, which is less than half of the value three weeks after installation, proving that the red rust had transformed into insoluble black rust in the water. As a result of the drastic reduction in iron content, the red water was eliminated. The existing red rust was reduced to black rust, which strengthened the piping. As long as the building continues to exist, the piping can continue to be used. With the red rust problem in the hot water pipes of Guildhall, London resolved, a letter of recommendation was issued. *We are currently offering free PDF materials such as customer testimonials (customer recommendation letters)!

Pipe rust prevention, the Imperial Theatre introduces NMR pipe protectors.

Pipe rust prevention, the Imperial Theatre introduces NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" completely prevents red rust in the air conditioning chilled and hot water pipes of the Imperial Theatre, where updating the piping is difficult, and has proven that it can extend the lifespan of the pipes until the building's lifespan.

Currently, at the Imperial Theatre, which was built 56 years ago, the "NMR Pipe Protector" was introduced in 2000 (Heisei 12) to prevent corrosion of the building's piping and to rehabilitate it, as the building reached 34 years of age. The Imperial Theatre building has its own heat source facilities for air conditioning, and the machinery room is located at the deepest point, which is the sixth basement level. Renovations and maintenance of various parts, such as water-based piping that is prone to aging, have been carried out quite frequently, but while exposed piping and equipment in the machinery room have been manageable, the buried piping could not be addressed. The effects of introducing the NMR Pipe Protector have been tremendous; this year marks 56 years since its construction, and the occurrence of red rust inside the piping has been remarkably suppressed. Additionally, there has been no leakage for the past 22 years since the installation, proving that the red rust has transformed into black rust. As a result, the NMR Pipe Protector has contributed to maintaining a comfortable theater environment at the Imperial Theatre, which symbolizes Japan's theatrical culture. *For more details, please refer to the PDF document or feel free to contact us.*

Pipe rust prevention: Buckingham Palace in the UK introduces NMR pipe protectors.

Pipe rust prevention: Buckingham Palace in the UK introduces NMR pipe protectors.

The red rust prevention device "NMR Pipe Protector" protected the air conditioning and hot water piping in the area used by Her Majesty, where updating the piping was impossible due to safety concerns, from deterioration caused by red rust.

At that time, Buckingham Palace was using galvanized steel pipes for air conditioning hot water piping and hot water supply piping, but due to deterioration from red rust, partial updates to the piping were being carried out outside of Her Majesty's areas. The circulating hot water in these pipes installed for Queen Elizabeth's room had been reddish-brown from the beginning due to red rust. Therefore, to make this reddish-brown water clear and to prevent red rust, as well as to extend the life of the piping, the "NMR Pipe Protector" was introduced. In the hot water supply piping, the level was reduced from 2.8 mg/L before installation to below 0.018 mg/L, which is less than 1/100, after 24 days, proving its effectiveness in preventing red rust. Additionally, the color of the water became clear, and the NMR Pipe Protector demonstrated its high performance in preventing red rust without reservation. *For more details, please refer to the PDF document or feel free to contact us.*

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

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 plastic waste polluting the oceans amounts to about 8 million tons. Developing countries with densely populated cities like Indonesia and Vietnam are major contributors to the marine plastic waste problem, as they consume large quantities of bottled beverages, many of which flow 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 can be resolved, there is a prospect of improving the marine pollution problem caused by plastic waste. In this regard, our company’s uniquely developed rust prevention device for pipes, the "NMR Pipe Protector," is highly anticipated. This product can resolve the rust problem 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," a product born from 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.*

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.
