聚氯乙烯管道和管道

PVC pipe and tubes Main charactricstics 1. PVC-U is a rigid unplasticized material with goodsurface rigidity and tensuile 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 of 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 can be adopted,easy to handle and install. Application areas: 1. Internal and external discharge piping for industrial and civil high buildings 2. Engineering project. 3. Agricultural irrigation.
