Main charactricstics

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.
