China Gas Pipe HDPE Pipe Gas Supply Pipe

Steel wire mesh reinforced polyethylene compositepipe for fuel gas supply1.Product introductionThis series of products are new-type medium, high or low-pressure composite pipes reinforced by high-strength plastic-covered steel wire and covered with composite thermal plastic at internal and external surface. Owning to the reinforcement is covered in continuous thermal plastic, this kind of composite pipe not only overcomes shortcomings of steel pipes and plastic pipes, but also has common advantages of steel pipes and plastic steels. Therefore, it is the preferred for the pipe for fuel gas. The piping system of steel wire mesh reinforced polyethylene composite pipes (plastic reinforced pipes) is equipped with electric melting pipe fittings. During connection, the heating elements in fittings will melt outer plastic on pipe and inner plastic on fittings and then connect them together reliably.
2. characteristicsHas the strength higher than that of plastic pipe, rigidity and impact resistance.
The anti-corrosive surfaces have the corrosion resistance as high as plastic pipe.
Operating temperature is high and heat conductivity coefficient is low, so insulation of outer wall is unnecessary in winter and no condensation will be formed in summer.
The inner wall is smooth and free of any scale sediment, so the head loss is 30% lower than that of steel pipe.
The technology to connect pipes by elecCapacitor tric melting is mature, electric-melting joints are highly resistant to axial tension and multiple fittings of various specifications and varieties are available.
It is convenient for transportation and construction because its weight is light. This pipe is high in general reliability. And, under normal circumstances, its service life is up to 50 years.
It is the best substitute of galvanized pipe because it is low in cost, hygienic and non-toxic.3.Specifications:
