Qingdao jingke plastic machinery co., LTD specializes in manufacturing PVC drain water supply pipe production line
In construction market, the use of PVC pipe has two kinds: one kind is pressure tube, one kind is no pressure tube. In the past the general use of cast iron pipe and brass as pressure building materials, not only severely corrosive, and require constant maintenance and replacement, high cost. Foreign building now widely used pressure water pipe, hot water supply pipe are mainly used for PVC pipe. Slim PVC tube (UPVC pipe, CPVC tube) with low cost, corrosion resistance, no need to often maintenance and replacement etc. And large diameter PVC pressure tube (diameter in the 100-900 mm) alternative cast iron pipe, enhance small pipe, water supply system good liquidity, corrosion resistant, low weight. Electricity saving, water quality is good. And with PVC core layer foaming no pressure tube as indoor downcomer and rainwater system pipe, can be very good solve interior of the pipe noise problem. Utility drainage pipe using no pressure PVC pipe, good resistance to corrosion, not affected by hydrogen sulphide erosion, long service life, light weight, low cost of installation, easy connection and seal, not easy to break. In addition, building seton tube and the underground cable protecting tube is PVC pipe another market, the current domestic the varieties are straight expanding, double wall pipe and single wall corrugated pipe.
