PVC-U Sewage Pipe

We offer PVC-U Sewage Pipe.
Description of PVC-U Sewage Pipe
Fosite PVC-U sewage pipe and fittings are manufactured in strict accordance with ISO3633:2002 and BS25224514. We supply complete sets of PVC-U sewage pipe and fittings which adopt solvent cement jointing.
Based on the high quality and with our many years experience of supplying Polygon PVC-U drain pipe and fittings, our products are widely sold all over the country and to the southeast Asia in various building drainage projects.
Feature of PVC-U Sewage Pipe
PVC-U is a rigid unplasticized material with good surface rigidity and tensile resistance, as well as high compressive rating and pipe safety factor.
1. Good aging resistance with normal lifetime up to 50 years;
2. Good chemical resistance to acids, alkalis and salts, suitable for sewage and industrial effluent disposal;
3. Low coefficient of friction of PVC-U pipe results in efficient flow and less needs for maintenance;
4. A combustion-proof material at grade B2 with high oxygen value, self extinguishing;
5. The Coefficient of linear expansion is 0.007mmm.℃, thermal expansion of PVC-U pipe is less than polyolefin by 100%-130%, low thermal conductivity and elastic modulus, better cold-resistance than cast iron sewage pipe;
6. Solvent cement jointing of pipe and fittings are easy to handle and install.
Jointing of PVC-U Sewage Pipe
1. The following procedures should be adhered when making socket-spigot jointing:
1) Clean the external surface of spigot and internal surface of socket before jointing.
2) Measure the depth of socket, and make the spigot at the distance equivalent to the depth of the socket.
3) Apply solvent cement, first spread to the internal surface of the socket, then to the pipe end evenly and in adequate quantity.
