[NMR Pipe Protector Verification Results] GSK Building

The red rust blockage rate has decreased by 57.3% to 5.3%! A case has been proven where pipe rehabilitation was achieved through the black rust transformation of red rust.

This property is 14 years old, and there has been significant red rust blockage at the joints of the dissimilar metal connections in the hot water supply pipes. To prevent future piping rehabilitation and renewal work, we adopted the "NMR Pipe Protector," which costs less than one-tenth of that, before the red rust blockage progressed any further. When measuring the red rust blockage rate at the first joint of the hot water supply piping for the circulation pump, it was 12.4% before the installation of our product, but it decreased by 57.3% to 5.3% four months after installation. 【Introduction Overview】 ■ Building Name: GSK Building ■ Location: Shibuya, Tokyo ■ Building Overview: 14 years old, office building ■ Water Supply Method: Circulating hot water supply method ■ Installation Date: September 22, 2003 ■ Installed Piping/Number of Installations: Hot water supply piping on the secondary side of the storage tank (HTLP 65mm)/PT-75DS×1 unit *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Teikoku Theatre Building

The red rust issue in the piping that occurred 21 years ago has been completely resolved! No leaks have occurred, and the piping condition has been maintained in good shape.

The heat source equipment of the Imperial Theatre uses steam boilers and turbo chillers, and since the theatre dislikes noise, the heat source is installed six floors underground. Additionally, most of the piping is located within concrete, making pipe renewal work extremely difficult. To improve the current situation where significant deterioration due to red rust in the piping has progressed after 34 years since its construction in 2000, the "NMR Pipe Protector" was installed to convert red rust to black rust and rehabilitate the piping. As of 2021, 21 years later, all issues related to red rust in the piping have been resolved, and there is almost no iron content from red rust in the circulating air conditioning chilled and hot water. Since the installation of this product, there has been no leakage at all, maintaining an extremely good condition of the piping. 【Effects After Installation】 ■ All issues related to red rust in the piping that existed 21 years ago have been resolved. ■ There is almost no iron content from red rust in the circulating air conditioning chilled and hot water. ■ There has been no leakage at all, maintaining an extremely good condition of the piping. *For more details, please refer to the PDF document or feel free to contact us.

NMR Pipe Protector Verification Results: Fenchurch Building

Nine days after installation, the iron concentration dramatically decreased to 0.5 mg/l! A case proving the rehabilitation of pipes through the black rusting of red rust.

The hot water supply piping in this office building uses galvanized steel pipes (SGP pipes) as the piping material, and serious red water due to corrosion deterioration occurred throughout the building. According to water quality tests, the iron content in the hot water supply in the early morning was high at 5.2 mg/l, so a "NMR Pipe Protector" was installed to prevent red rust and extend the life of the hot water piping. In the water quality test conducted nine days after installation, the iron content dramatically decreased to 0.5 mg/l, and even 43 days after installation, the iron content remained low at 0.5 mg/l. [Effects After Installation] ■ In the water quality test nine days after installation, the iron content dramatically decreased to 0.5 mg/l. ■ In the water quality test 43 days after installation, the iron content remained low at 0.5 mg/l. ■ The leaching of red rust into the water stopped, proving the rehabilitation of the piping through the black rust formation. ■ By preventing external corrosion, the piping became usable as long as the building remains standing. *For more details, please refer to the PDF document or feel free to contact us.

[NMR Pipe Protector Verification Results] Whittington Hospital, UK NHS

Measures to prevent red rust and leakage in hot water supply piping! Usable for 100 years or 200 years as long as the building exists!

At Whittington Hospital, galvanized steel pipes (SGP) had been used for hot water piping for over 30 years, resulting in the daily occurrence of dark red water and concerns about leaks. Before the installation of the "NMR Pipe Protector," the iron content in the hot water was very high at 7.33 mg/l, and the deterioration of red rust in the pipes was quite advanced. However, after 19 days post-installation, the iron content in the hot water decreased to 0.388 mg/l. After 29 days post-installation, it further reduced to 0.077 mg/l, which is 1/100 of the initial value, completely preventing the deterioration of red rust. It was proven that the red rust in the pipes transformed into insoluble and passive black rust in water at a volume of 1/10. [Effects After Installation] - After 19 days post-installation, the iron content in the hot water decreased to 0.388 mg/l. - After 29 days post-installation, it further reduced to 0.077 mg/l, completely preventing the deterioration of red rust. - By preventing external corrosion, this piping can be used for 100 years or even 200 years as long as the building remains standing. *For more details, please refer to the PDF document or feel free to contact us.*

[NMR Pipe Protector Verification Results] Moseley Hospital (NHS)

Prevent red rust and leaks in the hot water piping of Moseley Hospital!

Moseley Hospital has two independent hot water systems: one connected to the storage tank and the other connected to the hot water header, with galvanized steel pipes used in the hot water piping. As a result, NMR pipe protectors were installed in the storage tank piping and the hot water header piping to prevent red rust corrosion and leaks in both hot water systems. Water samples were taken from the hot water piping at five locations, and the average iron content in the water was calculated. Before the installation of the NMR pipe protectors, the average value was 13.824 mg/l. After 15 weeks of installation, it decreased to 1.3882 mg/l; after 31 weeks, it further decreased to 0.4762 mg/l; and after 49 weeks, it reached 0.3428 mg/l, showing a significant reduction. This result demonstrated that the NMR pipe protectors prevented the formation of new red rust within the pipes and reduced existing red rust to black rust, which is insoluble in water and has a volume that is one-tenth of that of red rust. It has been proven that by continuing to install NMR pipe protectors, the hot water piping will transform 100% of the red rust within the pipes into black rust, thereby extending the lifespan of the building.
