PVC Drainage Pipe

Main Characteristics 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 to acids, alkalis and salts, suitable for sewage and industrial effluent disposal. 4. Low coefficient of friction of PVC-U pipe results in efficient flow and less needs for maintenance. 5. PVC-U is a combustion-proof material is grade B2 with high oxygen value, self extinguishing. 6. The Coefficient of linear expansion is 0.007mm/m.,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. 7. Solvent cement jointing of pipe and fittings can be adopted, easy to handle and install.
