PVC-U труб

PVC INTRODUCTION Polyvinylchloride (PVC) [-(-CH2-CHCl-)n-] is one of the three most important polymers currently used worldwide. the cheapest polymers a large range of properties hundreds of products. PVC is formed by the polymerisation of vinyl chloride (chloroethane) monomer units: PVC was first developed in 1925 Apolyvinyl chloride(PVC) pipe is made from a plastic andvinylcombination material. The pipes are durable, hard to damage, and long lasting. A PVC pipe does notrust, rot, or wear over time. For that reason, PVC piping is most commonly used inwater systems, underground wiring, and sewer lines. specification PVC PIPE specification of PVC-U RAIN WATER PIPE 1.Brief description pvc-u rain water pipe NO.TEST ITEMSINDEX1tensile strength MPa432breaking elo0ngation%803Vertical reversion rate3.54Vicat softening temperture755 weatherabiltytensile conservation rate80color change rate36 drop hammer impact testtest way ATIR<=10%TEST WAY B12TIMES, no rupture 2.brief descrption pvc-u water pipe fittings NO.TEST ITEMSINDEX1VICAT softening temperature752oven testGB/8803 diameterthicknessspiral heightlengthbasic dimesionstoleranceBDTBDTBDT75+0.32.3-0.4 02.3-0.2 +0.24000,6000+-10110+0.43.2-0.3 +0.23.0-0.3 +0.34000.,6000+-10160+0.54.0_0.8 +0.43.8-0.4 +0.44000,6000+-10 physic performance NO.test itemsindex1tensile yield degreeabove40MPa2vicat softening tempertatureabove79degree3flat testno rupture4hammer drop testbelow10percent5vertical reversionbelow9.0percent
