The water supply piping made of galvanized steel with a statutory useful life of 15 years has been extended for 42 years until it reaches 57 years of age!
This property has been in existence for 37 years, and due to the use of SGP (galvanized steel pipes) in the water supply pipes, there has been an occurrence of red water. Furthermore, updating the piping requires a huge cost, and the necessary water outage work during the pipe renewal could not be carried out due to business operations within the building, making it impossible to repair the piping. Therefore, we adopted the "NMR Pipe Protector," which prevents the occurrence of red rust in the pipes by converting it to black rust without allowing red rust to flow out, thereby extending the life of the piping. Two months after installation, the complete leaching of red rust stopped, and three months after installation, an analysis of the black rust mass in the piping revealed that 63.5% of black rust was confirmed. [Introduction Overview] - Before installation: The iron ion concentration in the water inside the pipes was 2.2 mg/l, with a color degree of 50. - Effects after installation: - Two months after installation, the complete leaching of red rust stopped. - Three months after installation, an analysis of the black rust mass in the piping confirmed 63.5% black rust. - Even after 20 years, the water supply piping continues to be used without any red rust issues. *For more details, please refer to the PDF document or feel free to contact us.
