  1. Plastic composite pipe with steel wire mesh skeleton adopts high quality material and advanced production technology, which makes it have higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline system. The pipe fittings used in polyethylene composite pipe with wire mesh framework are polyethylene fused pipe fittings. When connecting, the outer plastic of the pipe and the inner plastic of the pipe are melted by the inner heating body of the pipe, and the pipe and the pipe are connected reliably.
  2、PE管的焊接,PE管道对接焊缝,该方法提供了的可靠性和直径的范围内和压力过程:加热的管子的端部,使用一个工具,称为接触压力和温度定义下的“镜像”。 端部被迅速接触,并保持在压力下,在冷却过程中。
  2. PE pipe welding, PE pipe butt weld, this method provides reliability and diameter range and pressure process: the end of heated pipe, using a tool, called "mirror image" under the definition of contact pressure and temperature. The ends are quickly contacted and kept under pressure during cooling.
  PE pipe has medium density polyethylene pipe and high density polyethylene pipe. According to wall thickness, it can be divided into SDR11 and SDR17.6 series. The former is suitable for transporting artificial gas, natural gas and liquefied petroleum gas, while the latter is mainly used for transporting natural gas. Compared with steel pipe, the construction technology is simple and flexible. More importantly, it is not used as anti-corrosion treatment, which will save a lot of working procedures. The disadvantages are not as good as the steel tube of the equipment, especially in the construction. The safety distance between heating and heating should be paid special attention, and it should not be exposed to the sunlight in the air, and it is sensitive to chemicals, so as to prevent the leakage of sewage pipes from causing injury.
