钢丝网骨架复合管跟PE管有什么区别?

  1、钢丝网骨架塑料复合管,采用了优质的材质和先进的生产工艺,使之具有更高的耐压性能。同时,该复合管具有优良的柔性,适用于长距离埋地用供水、输气管道系统。钢丝网骨架聚乙烯复合管采用的管件是聚乙烯电熔管件。连接时,利用管件内部发热体将管材外层塑料与管件内层塑料熔融,把管材与管件可靠地连接在一起。
  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管有中密度聚乙烯管和高密度聚乙烯管。根据壁厚分为SDR11和SDR17.6系列。前者适用于输送气态的人工煤气、天然气、液化石油气,后者主要用于输送天然气。和钢管比较,施工工艺简单,有一定的柔韧性,更主要的是不用作防腐处理,将节省大量的工序。缺点就器械性不如钢管,施工中特别的注意热力供暖的安全间距,并且不能裸露于空气中阳光下,并且对化学物品敏感,防止污水管道的泄露造成伤害。
  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.
