[NMR Pipe Protector Verification Results] Tower Building #T

The water supply piping made of galvanized steel with a statutory useful life of 15 years has been extended for 42 years until it reaches 57 years of age!

This property has been in existence for 37 years, and due to the use of SGP (galvanized steel pipes) in the water supply pipes, there has been an occurrence of red water. Furthermore, updating the piping requires a huge cost, and the necessary water outage work during the pipe renewal could not be carried out due to business operations within the building, making it impossible to repair the piping. Therefore, we adopted the "NMR Pipe Protector," which prevents the occurrence of red rust in the pipes by converting it to black rust without allowing red rust to flow out, thereby extending the life of the piping. Two months after installation, the complete leaching of red rust stopped, and three months after installation, an analysis of the black rust mass in the piping revealed that 63.5% of black rust was confirmed. [Introduction Overview] - Before installation: The iron ion concentration in the water inside the pipes was 2.2 mg/l, with a color degree of 50. - Effects after installation: - Two months after installation, the complete leaching of red rust stopped. - Three months after installation, an analysis of the black rust mass in the piping confirmed 63.5% black rust. - Even after 20 years, the water supply piping continues to be used without any red rust issues. *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Hospital #H

Preventing red rust leaching in the hospital's air conditioning chilled and hot water piping and demonstrating rust prevention effectiveness!

At Hospital #H, which was built 48 years ago, the air conditioning chilled and warm water piping using galvanized steel pipes (SGP) has shown significant deterioration due to red rust, leading to leaks. Therefore, we installed the red rust prevention piping extension device "NMR Pipe Protector." Before installation, we sampled the circulating chilled and warm water, and it was found that the total iron content in the water was 2.5 mg/l, indicating that red rust corrosion was progressing within the piping. Four weeks after the installation of our product, the total iron content in the chilled and warm water had significantly decreased to 0.4 mg/l. A sampling conducted six years after installation showed that the total iron content in the water further decreased to 0.2 mg/l, completely halting the progression of new red rust in the air conditioning chilled water piping. The existing red rust had transformed into insoluble, passivated black rust, with a volume reduced to one-tenth. [Introduction Overview] ■ Hospital Location: Hamamatsu City, Shizuoka Prefecture ■ Hospital Overview: 41 years old, 2 basement floors and 9 above-ground floors with 606 beds ■ Installation Date: December 2013 *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Hospital #I

Verification of rust reduction in chilled water of air conditioning systems and its anti-corrosion effect! Case study on measures to prevent leakage and extend the lifespan of air conditioning piping!

At Hospital #I, due to significant deterioration from red rust in the air conditioning chilled and hot water piping, which uses galvanized steel pipes (SGP) that are 19 years old, we installed a red rust prevention piping extension device called "NMR Pipe Protector" to prevent leaks. Before the installation of this product, we sampled the circulating air conditioning chilled and hot water, and found that the total iron content in the water was very high at 5.1 mg/l due to red rust, indicating considerable corrosion within the piping. Three weeks after the installation, sampling of the air conditioning chilled and hot water showed that the total iron content in the water had decreased to less than 0.03 mg/l, completely halting the progression of new red rust in the air conditioning chilled and hot water. It was confirmed that the red rust previously present in the piping had transformed into insoluble black rust, which is one-tenth the volume of the original. If Hospital #I continues to use this product, the air conditioning chilled and hot water piping will no longer require future replacements, and costs will be reduced to less than one-tenth, extending the lifespan of the building. *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Hospital #NT

A case where the progression of new red rust in the air conditioning chilled and hot water piping was completely halted just 52 days after installation!

The hospital, which was 27 years old at the time, was using galvanized steel pipes (SGP), and the red rust deterioration in the air conditioning chilled and hot water piping was very advanced, raising concerns about leaks. Before the red rust corrosion could progress any further, a red rust prevention piping extension device called "NMR Pipe Protector" was installed. After 52 days of installation, the water sampled from the air conditioning hot water system under the same conditions was clear, and the water quality test results showed that the iron ion concentration in the water was 0.27 mg/l, which is below the water quality standard value (1.0 mg/l) set by the Japan Refrigeration and Air Conditioning Industry Association. If this product continues to be installed in the hospital's air conditioning chilled and hot water piping, it has been verified that the red rust deterioration and leaks in the piping will be completely prevented, extending the piping's lifespan to match the building's lifespan. [Overview of Installation] ■ Hospital Location: Sendai City, Miyagi Prefecture ■ Hospital Overview: 27 years old, 5 stories, 199 beds ■ Installation Work: December 25 to 28, 2006 *For more details, please refer to the PDF document or feel free to contact us.

Piping with a statutory useful life of 15 years has been extended by 40 years! Maintaining the condition of the piping without red rust deterioration until 55 years of age.

In this property, galvanized steel pipes (SGP) are used for the water supply piping, and at 35 years old, it was diagnosed that the pipe's lifespan was only 2 months due to frequent leaks and the occurrence of red water. To prevent red rust and extend the life of the piping, an "NMR Pipe Protector" was installed. Before installation, water quality tests showed an iron content of 0.5 mg/l and the presence of dark red water, but six days after installation, the iron content dropped to below 0.05 mg/l and the red water was completely eliminated. Subsequently, water quality tests conducted 14 and 20 years after installation showed that red rust had completely disappeared, and new leaks were entirely prevented, proving the rehabilitation of the piping. [Effects After Installation] ■ Water quality tests six days after installation showed iron content below 0.05 mg/l and complete elimination of red water. ■ Water quality tests 14 and 20 years after installation showed that red rust had completely disappeared. ■ New leaks were entirely prevented, proving the rehabilitation of the piping. ■ Piping with a statutory useful life of 15 years was extended by 40 years, maintaining a condition free from red rust deterioration until 55 years of age. *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Hotel Serve Shibuya

[NMR Pipe Protector Verification Results] Hotel Serve Shibuya

Completely prevent water leakage damage from air conditioning piping used in hotels!

At Hotel Serve Shibuya, galvanized steel pipes (SGP) are used for the air conditioning chilled and hot water piping, and there was concern about the deterioration due to red rust and potential leaks from the joints. Therefore, a red rust prevention and leak prevention measure, the "NMR Pipe Protector," was installed. Before the installation of the NMR Pipe Protector, water samples were taken from the air conditioning chilled and hot water piping, revealing that the water was light brown in color and the total iron content was 5.8 mg/l, indicating significant red rust corrosion within the pipes. Two weeks after the installation of the NMR Pipe Protector, the total iron content in the water from the air conditioning chilled and hot water piping significantly decreased to 0.6 mg/l. In water samples taken four weeks after the installation, the water color had become almost transparent, and the total iron content further decreased to 0.5 mg/l. It was proven that new red rust was completely prevented in the air conditioning chilled and hot water piping, and the existing red rust had transformed into passive black rust. Moving forward, if the use of the NMR Pipe Protector continues to prevent external corrosion at Hotel Serve Shibuya, it has been demonstrated that all red rust in the air conditioning chilled and hot water piping will change to black rust, allowing this piping to be extended for the lifespan of the building. Naturally, leaks have been completely prevented thereafter.
