Formation and prevention of pipe scale in water supply pipelines with anti-corrosion lining

Abstract With the continuous requirement for an improvement in tap water quality, decline of quality after is transported through supply pipelines needs to be solved urgently. Pipe scale forms when anti-corrosive lining pipeline damaged, and it has a significant influence on chromaticity turbidity indicators quality. Therefore, reasons damage joint, tee, elbow, other parts that are prone damaging construction were investigated. On this basis, matters needing attention prefabricated proposed, suggested steel pipes should not used during if diameter less than 700 mm. A combination removal rehabilitation treat pipe ensure safe supply.
