Water supply piping extended for over 40 years by NMR pipe protector Part 2

- DPE Factory Water Supply Piping
This property, built 35 years ago, used galvanized steel pipes for the water supply piping, which led to leaks and the occurrence of red water due to red rust deterioration. A pipe diagnosis by experts indicated a lifespan of only 2 months, prompting the installation of NMR Pipe Protectors on the secondary side piping of the elevated water tank.
After installation, since over 800 tons of water were used daily, the rust prevention effect was quickly realized, resulting in no leaks and the red water issue was resolved within a week. Since then, until the factory closed in the summer of 2020, the water supply pipes were used for 55 years without any red rust problems. According to the "Life Cycle Cost of Buildings" supervised by the Ministry of Land, Infrastructure, Transport and Tourism, the lifespan of galvanized steel water supply pipes is 15 years, but this became an example of extending their lifespan by 40 years.
The main material of the current water supply pipes is vinyl-lined steel pipes, which have less red rust deterioration, so the installation of NMR Pipe Protectors is expected to enable even longer lifespan extension.
