"Water supply pipes and chilled/hot water piping require replacement due to aging." After 25 years, the chilled/hot water piping in hospitals experiences red rust deterioration, leading to red rust blockage. Simultaneously, this red rust flows and causes blockage within copper fan coils, reducing the efficiency of heating and cooling. Additionally, the red rust accumulates within the heat source equipment, shortening its lifespan. In the water supply pipes, red rust develops at the joints, and as the red rust deterioration progresses within both pipes, the threads at the joints may break off, leading to leaks during strong earthquakes. "Unnecessary replacement of water supply pipes and chilled/hot water piping." Iron oxidizes and forms red rust due to dissolved oxygen and water molecules in water. When electrons are supplied to the red rust, the water molecules and oxygen contained in the red rust are separated from it, transforming into a very hard black crystal that is one-tenth the volume of the red rust. Because it is black, it is called black rust. Black rust is inert like gold, so if all the red rust in the pipes is converted to black rust, the internal red rust deterioration will cease, preventing external corrosion and extending the lifespan of the building.
