Embodiment 1

[0016] Such as figure 1 , figure 2 , image 3 In the shown steel reinforced PE water supply pipe, a layer of steel mesh 2 is embedded in the pipe wall 1 of the pipe body. Embedded with steel rings 3,4. The steel rings 3, 4 are fixedly connected with the steel mesh 2 by welding. The steel rings 3, 4 are integrally formed with the pipe body. The steel rings 3 and 4 are shaped steel.

[0017] A steel-reinforced PE water supply pipe connection structure, comprising two water supply pipes as described above, one end interface of the first water supply pipe is welded and fixed to one end interface of the second water supply pipe.

[0018] When the above-mentioned water supply pipe is manufactured, the steel rings are first embedded in both ends of the PE plastic pipe, and the steel mesh steel wire is anchored on the steel ring at one end, and the steel wire is uninterruptedly wound on the PE plastic pipe to form an intermediate layer. The other end is anchored on the steel ri...

Abstract

The invention discloses a steel reinforced polyurethane (PE) water supply pipe. At least one layer of steel mesh is embedded into the pipe wall of a pipe body; pipe walls at interface positions of two ends of the pipe body are thickened walls; and steel rings are embedded into the thicken walls. The invention also discloses a steel reinforced PE water supply pipe connection structure. The connection structure comprises two water supply pipes, wherein one end interface of the first water supply pipe is welded and fixed with one end interface of the second water supply pipe. Through the scheme, the thickened walls and the steel rings are formed at connection positions to keep the roundness of a pipe orifice, the requirement of welding difficulty is reduced, pressure resistance is improved, service life is prolonged, and deformation and water leakage are avoided.

Description

technical field [0001] The invention belongs to the field of plastic pipe manufacture, and in particular relates to a steel mesh reinforced PE water supply pipe and a connection structure for connecting multiple water supply pipes. Background technique [0002] Steel mesh reinforced PE water supply pipe, by embedding steel mesh in the pipe wall, it realizes the use of less plastic raw materials to make high-strength reinforced plastic pipe. As a new type of pipe, its pressure resistance has been significantly improved, and the production cost and the same pressure Compared with the grade of pure plastic pipe, the overall advantage has been recognized by the market. However, in the prior art, because steel mesh reinforced PE water supply pipes are still all connected by electrofusion pipe fittings, the phenomenon of pipeline leakage is relatively common. It is large and also increases the hidden danger of water leakage, and because the connection position of the water supply...
