19 months after installation, all red rust has turned to black rust! The air conditioning hot and cold water pipes can be used as long as the building remains standing.

The air conditioning chilled and hot water piping installed throughout the famous bookstore building in Shinjuku was at risk of deterioration due to red rust. In 2005, 41 years after its construction, a "NMR Pipe Protector" was installed on a 200A diameter pipe before the heat source pump to prevent the deterioration of red rust in the piping and convert it to black rust, thereby extending the lifespan of the piping to match the lifespan of the building. In April 2007, 19 months after installation, a branch pipe with a diameter of 32A from the air conditioning chilled and hot water piping was removed to check the condition of the red rust inside the piping, and it was found that all the red rust had converted to black rust. 【Overview of Installation】 ■ Location: Shinjuku, Tokyo ■ Year of Completion: 1964 ■ Pipe Material: Galvanized Steel Pipe ■ Air Conditioning Method: Central System (Warm Water Piping) ■ Installation Work: 2005 *For more details, please refer to the PDF document or feel free to contact us.
