[NMR Pipe Protector Verification Results] Tower Building #T

[NMR Pipe Protector Verification Results] Tower Building #T

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

This property has been in existence for 37 years, and due to the use of SGP (galvanized steel pipes) for the water supply pipes, there has been an occurrence of red water. Additionally, updating the piping requires a huge cost, and the necessary water outage work during the piping update 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 leak out, thus 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 showed 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 the leaching of red rust 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 from the air conditioning system, revealing a total iron concentration of 2.5 mg/l, indicating that red rust corrosion was progressing within the pipes. Four weeks after the installation of our product, a subsequent water sample showed a significant reduction in total iron concentration in the chilled and warm water to 0.4 mg/l. A water sample taken six years after installation showed the total iron concentration further decreased to 0.2 mg/l, completely halting the progression of new red rust within the air conditioning chilled water pipes. The existing red rust had transformed into an insoluble, passive 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 for anti-corrosion effectiveness! Case study on measures to prevent leaks and extend the lifespan of air conditioning piping!

At Hospital #I, due to the significant deterioration of 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 that corrosion from red rust in the piping was quite advanced. Three weeks after the installation, a sample 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 demonstrated that the red rust that had been present in the piping had transformed into insoluble black rust, which is 1/10th 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 updates in the future, and costs will be reduced to less than 1/10th, 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 completely stopped just 52 days after installation!

The hospital had been built for 27 years at the time, and the air conditioning chilled and warm water piping, which used galvanized steel pipes (SGP), was experiencing significant deterioration due to red rust, 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, under the same conditions, the water sampled from the air conditioning warm water showed a transparent color, and the water quality test results indicated 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 warm 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 that of the building. [Introduction Overview] ■ 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.

[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 a concern about the deterioration due to red rust and leakage from the joints. As a countermeasure against red rust deterioration and leakage, a red rust prevention pipe longevity device called "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 tinted light brown, with a total iron content of 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 within the air conditioning chilled and hot water piping significantly decreased to 0.6 mg/l. In a water sample taken four weeks after the installation, the water was nearly transparent, with the total iron content further reduced to 0.5 mg/l. It was proven that new red rust was completely prevented within the air conditioning chilled and hot water piping, and the existing red rust had transformed into inert black rust. Going forward, if the use of the NMR Pipe Protector continues to prevent external corrosion at Hotel Serve Shibuya, all red rust in the air conditioning chilled and hot water piping will change to black rust, and it has been demonstrated that this piping can be extended to the lifespan of the building. Naturally, leakage has been completely prevented thereafter.
