Manufacturer Supply High Quality and Lightweight UPVC Pipe for Environmental Protection Water Supply Irrigation DN20 DN25 DN32

PVC-U Environmental Protection Water Supply Pipe :          PVC-U pipes are made of sanitary grade polyvinyl chloride (PVC) resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, extension agents, etc. added through extrusion molding by a plastic extruder and molding by an injection molding machine. Curing, shaping, inspection, packaging and other processes to complete the production of pipes and fittings.     Compared with traditional pipes, PVC-U pipes have the characteristics of light weight, corrosion resistance, small water flow resistance, energy saving, quick installation, and low cost. They have been vigorously promoted and applied with remarkable results. The application of PVC-U pipes in municipal engineering and construction projects has become an indispensable and important product for civil buildings and household drainage projects.     Material:PVC,polyesterProjectIndicatorsdensity(kg/m3)1350~1460Vicat softening temperature(ºC)≥80Longitudinal retraction≤5Dichloromethane Immersion Experiment,15 ºC15minSurface change not inferior to 4N TIR≤5hydraulic testdn
