Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 2 of the drawings, an improved polyethylene composite pipe according to an embodiment of the present invention includes an inner pipe layer 1, a steel wire reinforcement layer 2, a PE layer 3, and a protection layer 4 from inside to outside, where the protection layer 4 is made of PP, the protection layer 4 directly covers the outer surface of the PE layer 3, the inner surface of the protection layer 4 is smooth, the protection layer 4 is in close contact with the PE layer 3, easy-to-tear lines 5 are annularly arranged at edges of two ends of the protection layer 4, and a predetermined distance is formed between the easy-to-tear lines 5 and the end portions close to the easy-to-tear lines 5.

In some embodiments, the outer end portion of the protective layer 4 corresponding to the tear line 5 may be a peelable PE layer. When the polyethylene composite pipes between adjacent pipes are connected. The protective layer is peeled off through the easy-to-tear line, and the smooth PE layer is leaked and connected through the electric hot-melting pipe fitting.

Specifically, the PE layer 3 corresponding to the part of the stripping protective layer 4 can be connected with an electric hot-melting pipe fitting 6, and the outer surface of the stripped PE layer is a fresh surface and is reliable in connection.

In other embodiments, the predetermined distance between the tear line 5 and the end adjacent thereto is 15cm, and there is sufficient length to connect the electrofusion tube.

Specifically, the thickness of protective layer 4 is 3mm, has sufficient thickness to prevent ultraviolet irradiation PE layer, also satisfies the thickness requirement of preventing the fish tail, and the further PE layer of being convenient for to take off the cover for it is comparatively convenient when constructor connects the electric heat fused pipe spare.

In other embodiments, the inner tube layer has a thickness of 2 mm. The thickness of the steel wire reinforcement layer is 5 mm.

Specifically, the inner pipe layer and the steel wire reinforcing layer are fixedly bonded through hot melt adhesive.

More specifically, the inner tube layer is formed by pressing a PE material film.

The PP protective layer on the outer side can block ultraviolet irradiation, and is scratched on the protective layer in the pipe conveying and construction processes, so that the performance of the pipe body is not influenced.
