Background

HDPE pipe is a pipe made of high density polyethylene. HDPE pipes are the replacement products of traditional steel pipes and polyvinyl chloride drinking water pipes. HDPE pipe must withstand a certain pressure, and a PE resin with a high molecular weight and good mechanical properties, such as HDPE resin, is usually selected. LDPE resin has low tensile strength, poor compression resistance, poor rigidity, poor dimensional stability during molding and processing, and is difficult to connect, and is not suitable as a material for water supply pressure pipes. However, due to their high hygienic standard, LDPE, particularly LLDPE resins, have become a common material for the production of drinking water pipes. LDPE and LLDPE resins have small melt viscosity, good flowability and easy processing, so the selection range of the melt index is wide, and the MI is usually between 0.3 and 3g/10 min.

Common HDPE pipe structure is comparatively single, only utilizes self structure to play the guard action, and whole resistance to compression is comparatively limited with stretch-proofing effect when receiving external factor influence, takes place the damage easily.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a stretch-proofing HDPE pipe for cable protection as shown in fig. 1-2, including outer tube 1 and enhancement layer 2, the inner wall upper berth of outer tube 1 is equipped with buffer layer 4, and buffer layer 4's inner wall surface evenly integrates the shaping in proper order and has stopper 5.

The reinforcing layer 2 is an integrated structure made of steel sheet materials, the thickness of the reinforcing layer 2 is 5-8 mm, the strength and the rigidity are good, an effective protection effect can be achieved, meanwhile, the compression and impact resistant effects of the pipe body are improved, and the overall tensile resistant effect is further improved; the surface of the reinforcing layer 2 and a limiting block 5 on the surface of the buffer layer 4 are correspondingly provided with a limiting groove 6, the reinforcing layer 2 is fixedly bonded with the limiting block 5 arranged on the buffer layer 4 in an embedded manner through the limiting groove 6, the inner wall of the reinforcing layer 2 is bonded with a tensile layer 7, and the inner wall of the tensile layer 7 is filled with an inner tube 3; wherein buffer layer 4 lays the integral structure that forms for rubber materials, and tensile layer 7 lays the integral structure that forms for silica gel materials, can play the auxiliary protection effect, effectively plays the effect that whole stretch-proofing was prevented, avoids receiving external factors to influence and makes the body take place to damage easily.

The outer pipe 1 and the inner pipe 3 are of an integrated structure made of HDPE materials, so that the overall protection effect of the pipeline is ensured, and the pipeline can be embedded and assembled by matching with a cable; wherein the one end surface of outer tube 1 is equipped with first connecting piece 8, and the other end surface of outer tube 1 is equipped with second connecting piece 9, and first connecting piece 8 corresponds set up threaded hole with the surface of second connecting piece 9, can be convenient for cooperate the staff to use locking screw 10 to cooperate the equipment work.
