Novel PE-C pipe with injection molding joint

Technical Field

The invention relates to the technical field of pipe structures, in particular to a novel PE-C pipe with an injection molding joint.

Background

The winding structure wall pipe PE C is formed by winding inner layer PE on a mould and simultaneously combining the inner layer PE with a rib pipe which coats the PE material on the outer surface of the PP single-wall corrugated pipe. Two ports of the pipe are spiral ports, and due to the structural reason of forming the ribbed pipe, a certain gap exists between two sides of the bottom of the ribbed pipe and the inner layer PE, so when the two pipes are connected by using the heat shrinkable sleeve, leakage is easily caused because the gap cannot be sealed; and the distance between two ribbed pipes is short, so when the electric hot-melt belt is used, the welding position is too narrow, the welding strength is low, the pipe is easy to damage or drop due to the influence of external force, the welding is not firm, and the construction is difficult.

The existing winding structure wall pipe is connected by using an electric hot melting belt and a heat shrinkage sleeve, the connection effect is poor, the ring stiffness consistent with the pipe cannot be borne, the leakage is easy, and the leakage is not firm, so that the problem that the PE C pipe with the winding structure wall pipe, which is convenient to connect, high in ring stiffness and free of leakage and provided with an injection molding joint, is urgently needed to be solved is developed.
