Difference between u-PVC drain pipe and pressure hard polyvinyl chloride water supply pipe (UPVC)
PVC general PVC, there is a hose, can be used as temporary pipe; UPVC rigid PVC strength than ordinary PVC higher, plastic relative handicap, water supply and drainage with this, such as rainwater pipe.
PVC PVC, English (Polyvinyl chloride, referred to as PVC) is a vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxide, such as azo compound initiator; or in light, under the action of heat polymerization by free radical reaction mechanism of polymerization of polymers. The vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resins.
From the material, there is no difference. UPVC drainage and pressure feed water UPVC are only different in wall thickness. Because of the high rainfall considered a full pipe flow, so the pipe at the bottom needs pressure.There is no pressure test in the standard, so it is generally not pressure, and the water supply pipe must be under pressure.But you have used UPVC water supply pipe instead of rainwater drainage, and there is no pipe fitting in the water supply system of the pipe fittings.Or with HRS high-rise stormwater dedicated tubes, but also PVC materials, and pipe fittings are also pressure. The price is cheaper than the pipe.
