Xiangsu drain pipes, fittings are manufactured in strict accordance with the national standards of "PVC-U pipe for building drainage" GB/T19002-1994 and ISO2000. Xiangsu supplies complete sets of PVC-U drain pipe, fittings which adopts solvent cement jointing. Xiangsu drainage pipes, fittings which are sold throughout the country and to the southest Asia in full varieties and suitable for various building drainage projects. For the recent years, our research personnel sum up the application experience of different places, put out more reliable, more convenient to install PVC-U drain pipes, fittings, thus brought the application technology of PVC-U drain pipe up to a new level.

Xiangsu drainage pipes, fittings which are sold all over the country and to the southest Asia are in full varieties and suitable for various building draingae projects. For the recent year, our research prsonnel sum up the application experience of different places, put out more reliable, more convenient to install PVC-u drain pipe, fittings, thus brought the application tehnology of PVC-U drain pipe up to a new level.

1. PVC-U is a rigid unplasticized material with good surface rigidity and tensile resistance, as well as high compressive rating and pipe safety factor
2. PVC-U has good aging resistance with normal lifetime up to 50 years
3. Good chemical resistance including acids, alkalis, salts resistance, suitable for sewerage and industrial effluent disposal
4. Low coefficient of friction fo PVC-U pipe results in efficient flow and less maintenance
5. PVC-U is a combustion-proof material of grade B2 with high oxygen value, self extinguishing
6. Low coefficient of linear expansion of, thermal expansion of PVC-u pipe is less than polyolefin by, low thermal conductivity and elastic modulus, better cold-resistance than cast iron drain pipe
7. Solvent cement jointing of pipe and fittings cen be adopted, easy to handle and install.

1. The following precedures should be adhered to when making socket-spigot jointing;
1)Clean external surface of spigot and internal surface of socket before jointing
2)Measure the depth of socket, mark the spigot at the distance equivalent to the depth of the socket.
3)Apply solvent cement, first spread the internal surface of the socket, then to the pipe end evenly and in adequate quantity.
4)Push the pipe into the socket till reaching the mark, then rotate it by 90,
5)Remove all excessive solvent cemtn around the joint.
6)The joint should be left undisturbed until become solid.
