Red rust is reduced to a strong passive black rust! A proven case of protection and extension of life within piping.
The university's air conditioning hot water piping has been troubled by internal red rust issues. Although a sacrificial anode was introduced in 2008 as a countermeasure, the progression of red rust did not stop. Additionally, a rust inhibitor was administered once a year, but there was no change in the iron content in the water before and after the use of the rust inhibitor, raising concerns about its effects on human health. Therefore, to remove red rust and single-celled bacteria while maintaining the strength of the piping, an "NMR Pipe Protector PT-75DS" was installed in the air conditioning hot water piping (return pipe) of the Todd Building on campus. The iron content in the water, which was 43.81 mg/l before installation, decreased to 17.95 mg/l three weeks after installation. [Issues] ■ The progression of red rust did not stop despite the introduction of a sacrificial anode. ■ Although a rust inhibitor was administered once a year, there was no change in the iron content in the water before and after its use, and concerns were raised about its effects on human health. *For more details, please refer to the PDF document or feel free to contact us.
