[NMR Pipe Protector Verification Results] St. Ignatius Church

[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.

[NMR Pipe Protector Verification Results] Windsor Castle

[NMR Pipe Protector Verification Results] Windsor Castle

Preventing red rust deterioration of the hot water piping at Windsor Castle in the UK!

The hot water supply pipes used in Windsor Castle, owned by the British royal family and with a history of 900 years, utilize SGP pipes. To prevent red rust deterioration and extend the lifespan of the pipes, an NMR Pipe Protector was installed on January 24, 2007. Before the installation of the NMR Pipe Protector, the iron content in the water in Room 107 was 3.32 mg/l, but 42 days after installation, it dropped to 0.007 mg/l. Additionally, the average iron content from two other sampling locations was 4.255 mg/l before installation, but decreased to 0.0105 mg/l after installation. This is significantly lower than the drinking water quality standard set by the UK, which is 0.2 mg/l. As a result, it has been demonstrated that the NMR Pipe Protector effectively prevents the occurrence of new red rust within the pipes and transforms existing red rust into black rust, which does not dissolve in water. By continuing to use the NMR Pipe Protector, the hot water supply pipes have completely eliminated internal red rust deterioration and, by preventing external corrosion, have become usable for as long as the building remains standing.

U.S. patent obtained for pipe rust prevention, NMR pipe protector popular in the UK.

U.S. patent obtained for pipe rust prevention, NMR pipe protector popular in the UK.

Introducing examples of the red rust prevention effects of the "NMR Pipe Protector" in pipes in the UK!

The red rust prevention device for piping, "NMR Pipe Protector," has obtained patents and registrations in the United States and major countries around the world after undergoing rigorous patent examinations abroad regarding its practicality and other factors. On February 16, 2004, the first installation in the UK was at Addenbrooke's Hospital, affiliated with the University of Cambridge. The NMR Pipe Protector holds a patent in the UK and established its reliability through presentations at conferences related to "corrosion," leading to its installation based on a recommendation from the University of Cambridge. At Addenbrooke's Hospital, the hot water pipes experienced leaks due to bacterial corrosion and red rust deterioration just three years after the piping was updated. However, after the installation of the NMR Pipe Protector, red rust in the galvanized steel hot water piping was prevented in just 11 days. The iron ion concentration due to red rust in the hot water decreased from 1.07 mg/L before installation to 0.188 mg/L after 11 days, falling below the water quality standard of 0.2 mg/L. This change, where the red rust in the hot water pipes transformed into black rust with a volume reduction of one-tenth, verified the red rust prevention effect of the NMR Pipe Protector. 【Case Studies (Partial)】 ■ Addenbrooke's Hospital ■ St Thomas' Hospital ■ Harrods Department Store ■ BBC (British Broadcasting Corporation)

Extending the life of apartment water supply pipes is achieved by converting red rust to black rust.

Extending the life of apartment water supply pipes is achieved by converting red rust to black rust.

The piping internal red rust prevention device "NMR Pipe Protector" reduces red rust in the water supply pipes of apartments to insoluble and passive black rust, extending the lifespan of the building.

In addition to pipe rehabilitation, there is the "NMR method," which uses our internal rust prevention device, the "NMR Pipe Protector," to reduce red rust to insoluble and passive black rust in water. Vinyl-lined steel pipes are commonly used for condominium water supply piping, where the straight sections do not deteriorate from red rust, but only the joints do. By converting this red rust to black rust, pipe renewal becomes unnecessary, reducing costs to 1/5 to 1/10. The NMR Pipe Protector utilizes free electrons in water to convert internal red rust to black rust. Since the NMR Pipe Protector is installed on the outside of the pipe, it does not come into direct contact with the water inside, making it hygienic and safe. Through on-site surveys by our technical workers, we can implement our product at suitable installation locations, allowing for appropriate pipe rehabilitation throughout the entire piping system. The NMR method has obtained a patent as a groundbreaking pipe rehabilitation technique and has been presented in research papers at the "Asia-Pacific Corrosion Society" and the "Japan Society of Corrosion Engineering," receiving positive evaluations. It has been highly regarded for its water quality safety and has been adopted in many renowned hospital facilities around the world. The NMR Pipe Protector comes with a rust prevention effect guarantee, so you can implement it with confidence. *For more details, please refer to the PDF or contact us.*

The apartment water supply pipes are prone to leaks due to deterioration from red rust, and you may not even notice it!

The apartment water supply pipes are prone to leaks due to deterioration from red rust, and you may not even notice it!

By protecting only the joint parts of the water supply pipes in the apartment with the red rust prevention device "NMR Pipe Protector," pipe replacement is unnecessary.

The water supply pipes in buildings such as condominiums are made of vinyl-lined steel pipes, so the straight sections do not deteriorate; only the joints experience red rust deterioration. Since there is no change in the color of the water coming from the faucet and no red water is produced, it is difficult to notice the red rust deterioration inside the pipes. Our company will first conduct an on-site inspection using an endoscope to investigate the customer's red rust deterioration status, and based on that, we will propose the optimal introduction of the "NMR Pipe Protector." With this product, it is possible to prevent red rust deterioration throughout the entire piping, including the joints. By introducing this product, we can eliminate the need for piping replacement costs, which can be a significant financial burden for customers within limited repair budgets, and extend the life of the existing pipes for over 40 years, thereby prolonging the lifespan of the pipes until the building's lifespan ends. *For more details, please refer to the PDF materials or feel free to contact us.

The "seismic strength" of water supply piping deteriorates over time due to the loss of thread integrity.

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 exterior of the building does not reveal the condition of corrosion deterioration of the threads. If corrosion deterioration of the threads progresses unnoticed, it can lead to pipes coming loose and causing water leaks due to shocks during earthquakes. To maintain the seismic strength of the piping, it is necessary to perform rust prevention treatment inside the pipes before the threads deteriorate due to red rust. Our internal rust prevention device, 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 rust prevention effects, but the transformation of red rust to black rust also strengthens and rehabilitates the piping. For the safety of our customers, it is advisable to recheck 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 materials or feel free to contact us.

Cosmo Kajigaya Le Seine has introduced NMR pipe protectors to prevent red rust in piping.

Cosmo Kajigaya Le Seine has introduced NMR pipe protectors to prevent red rust in piping.

The management association of "Cosmo Kajigaya Le Seine" has verified the prevention of red rust deterioration in water supply pipes using the red rust prevention device "NMR Pipe Protector," ensuring long-term pipe longevity.

In the condominium "Cosmo Kajigaya Le Seine," which introduced the NMR Pipe Protector, polyvinyl chloride lined steel pipes (VLP) were used for the water supply piping. Polyvinyl chloride lined steel pipes (VLP) are pipes that are internally coated with polyvinyl chloride. The joint sections of the piping deteriorate due to red rust, but the straight sections are excellent in durability and corrosion resistance, and are currently used in most buildings' water supply pipes. However, this water supply piping has high maintenance costs, and after several decades of installation, measures against water leaks due to red rust at the joints are necessary. Many water supply pipes experience issues such as red rust blockage at the joint sections, water leaks, and deterioration of water quality after twenty years. The NMR Pipe Protector converts red rust into black rust, resolving these issues. Unlike pipe renewal work, the NMR Pipe Protector can be installed without water interruption, transforming the red rust inside the water supply pipes into black rust that strengthens the piping. By introducing the NMR Pipe Protector, red rust becomes inert black rust, extending the lifespan of the piping by over 40 years. *For more details, please refer to the PDF materials or feel free to contact us.

Pipe rust prevention: The Royal Bank of Scotland introduces NMR Pipe Protector.

Pipe rust prevention: The Royal Bank of Scotland introduces NMR Pipe Protector.

The Royal Bank of Scotland confirmed the rust prevention and lifespan extension effects of NMR pipe protectors for air conditioning pipes, reducing pipe replacement costs to less than one-tenth.

As an example of the introduction of the "NMR Pipe Protector," we would like to present the case of the Royal Bank of Scotland. Branch 250 had been in operation for 18 years and was facing issues with red rust in the air conditioning hot water piping. Due to the high cost of rust inhibitors and the shift towards environmental considerations, the "NMR Pipe Protector" was installed in the air conditioning hot water piping in March 2018. As a result of the installation, the iron content in the hot water, which was previously 1.10 mg/L due to red rust, was re-examined nine weeks after the installation of the NMR Pipe Protector, revealing that the hot water was clear and the amount of dissolved iron had decreased to approximately one-third, or 0.41 mg/L. The progression of red rust within the piping also stopped, and the red rust had transformed from a surface state to black rust. The NMR Pipe Protector successfully resolved the issue of red rust dissolving into the water and halted its progression. There is now no longer a concern about the acceleration of piping deterioration due to red rust. Additionally, the coating of black rust has a reinforcing effect on the piping, and it is expected to extend the lifespan of the piping to match that of the building. *Customer feedback (customer testimonials) and other PDF materials are currently available for free! *Please feel free to contact us first.
