[NMR Pipe Protector Verification Results] Office Building #TK

Prevent the progression of red rust and demonstrate the rehabilitation of piping due to black rust! A case where the amount of black rust increased to 16.9%.

At that time, the facility had been in operation for 42 years, and there were significant concerns about the corrosion of the hot water supply piping, which led to the adoption of the "NMR Pipe Protector." Before the installation of this product, the amount of black rust in the piping was 0.9%, but after 6 months of actual operation following installation, it increased to 16.9%, a relative increase of 1877.7%. The reduction of red rust to magnetite (black rust) has been demonstrated. In the future, if all the red rust turns into black rust, the piping will not require replacement as long as external corrosion does not occur. 【Introduction Overview】 ■ Location: Shibuya, Tokyo ■ Building Overview: 42 years old, 9-story office building ■ Installation Date: January 27, 2016 ■ Installed Piping: Cooling water pump primary side hot water supply piping (SGP pipe 200mm) ■ Number of Installations: PT-200DS × 1 unit *For more details, please refer to the PDF document or feel free to contact us.
