The difference between PSP and PPR pipe

Comparison of PSP steel-plastic composite pressure pipe and pure plastic pipe: high mechanical strength---adapted to the harsh environment of the construction site, low linear expansion coefficient---no deformation when exposed to installation; stable pressure-bearing performance with long compensation distance---not temperature-dependent Change and change higher safety-working pressure 3.2Mpa, strong water shock resistance. Comparison of steel-plastic composite pressure pipe with steel-lined plastic and steel coating: internal and external anti-corrosion, full plastic sealing, non-corrosive joints, advanced, completely in line with the pipe Fluid isolation, no water channeling, and no corrosion. Advanced one-time forming process, high composite strength, high pressure bearing, wide application range, service life of more than long-term durability according to standards, and the same life as construction. Comparison of steel-plastic composite pressure pipes and steel pipes: good sanitary performance, Good internal and external anti-corrosion hydraulic conditions, low friction resistance, reliable connection, light weight, high installation efficiency
