[NMR Pipe Protector Verification Results] Harrods Department Store

The inspection 67 days after installation showed that the iron concentration decreased further to 0.022 mg/l! Demonstrating the effectiveness of rust prevention and extending the lifespan of the piping.

At Harrods Department Store, galvanized steel pipes were used for the hot water supply system, and after 30 years, red water had occurred. To eliminate the red water in the hot water supply and prevent the need for pipe replacement, an "NMR Pipe Protector" was installed on the primary side of the hot water header. The iron content in the stagnant water at night, which was 1.294 mg/l before installation, decreased to 0.058 mg/l 47 days after installation, and further dropped to 0.022 mg/l 67 days after installation, reducing to 1/58 of the initial value. [Effects After Installation] ■ The iron content in the stagnant water at night decreased from 1.294 mg/l to 0.058 mg/l 47 days after installation. ■ 67 days after installation, the iron content was reduced to 0.022 mg/l, which is 1/58 of the initial value. ■ The deterioration caused by red rust from the inside has been completely eliminated. ■ By preventing external corrosion, it has become usable semi-permanently as long as the building remains. *For more details, please refer to the PDF document or feel free to contact us.
