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.
