1.Good Toughness and High Pressure ResistanceThe high strength reinforcement material is used for the pipe body, so the radial and axial resistance of the pipe is greatly enhanced, which leads to the good toughness and high pressure resistance.2.Designed with Double Sealing SocketOne end of each finished pipe is equipped with double sealing socket with rubber ring and electric fusion. During construction, the pipe can be directly connected to the pipe without additional pipe fittings.3.Double safety Connection TechnologyThe pipeline interface adopts the double sealing of rubber ring and electric fusion, which forms the strong advantages of the two interface processes.  It retains the superior sealing performance of the rubber ring, has strong adaptability to the environment after welding and reduces the dependence on the thrust cap.
