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 the attached drawings 1 to 4 of the utility model, the double-reinforced steel wire mesh reinforced polyethylene composite pipe according to the embodiment of the utility model comprises a core pipe 1, a steel wire reinforcing layer 2, a PE layer 3, a PP protective layer 4 and a self-adhesive reinforcing belt 5, wherein the core pipe 1 is a PE material pipe, and the steel wire reinforcing layer 2 is coated on the periphery of the core pipe 1 and is fixedly bonded through a hot melt adhesive layer; the PE layer 3 is uniformly coated on the periphery of the steel wire reinforcing layer 2 and fixedly bonded with the steel wire reinforcing layer; the PP protective layer 4 is uniformly coated on the periphery of the PE layer 3 and is abutted against the outer surface of the PE layer 3; the self-adhesive reinforcing tape 5 is wound on the circumference which is close to the two ends of the PP protective layer 4 and is at a preset distance d from the end part of the PP protective layer, namely, the preset distance along the axial direction of the core tube, and the d can be 10-20cm, so that the pressure bearing capacity of the joint is increased.

In some embodiments, the PE layer 3 is bonded to the outer periphery of the steel reinforcing layer 2 by a hot melt adhesive.

In other embodiments, the self-adhesive reinforcing tape 5 is wound on the outside of the PP protective layer 4.

In other embodiments, the self-adhesive reinforcing tape 5 is wound inside the PP protective layer 4.

Specifically, the thickness of the PP protective layer 4 is 3 mm.

More specifically, predetermined distance d is 10cm, the connection of the hot melt pipe fitting of being convenient for, when adopting the hot melt pipe fitting to connect, peel off the PP material of PP protective layer tip predetermined distance with the art designer's sword, and peel off the material of the PP protective layer of self-adhesion reinforcing band outer end, spill inboard PE layer, wear the cover with the hot melt pipe fitting between adjacent compound pipe and on the PE layer that corresponds, the internal diameter and the PE layer surface butt of hot melt pipe fitting, the hot melt pipe fitting circular telegram for it bonds as an organic wholely.

More specifically, the thickness of PE layer 3 is 10mm, and heating temperature influences the steel wire enhancement layer when preventing the hot melt pipe fitting from connecting, avoids the unstability.

In other embodiments, the self-adhesive reinforcing tape may be any one of a tape adhesive tape made of PE material, a tape adhesive tape made of fiberglass material, a tape adhesive tape made of PVC material, and a tape adhesive tape made of stainless steel material, and may also be a PP ring, a PE ring, a PVC ring, a stainless steel ring, and a glass steel ring having a certain width. The strength of the joint can be enhanced. The stability and the pressure bearing capacity of the joint are improved.

The double-reinforced steel wire mesh reinforced polyethylene composite pipe solves the problems that the traditional polyethylene composite pipe is not scratch-resistant and is prevented from aging due to ultraviolet irradiation, the service life of the composite pipe is prolonged, and the condition that workers need to polish the pipe at the pipe butt joint position by using a grinder until the outer diameter of the pipe is less than or equal to the inner diameter of the pipe when the traditional composite pipe is connected is avoided, so that the butt joint contact surface of the pipe is fresh, the reliable connection process is realized, the construction cost is reduced, the connection quality is easy to control, and the construction time is short.

Most of composite pipes connected by the traditional process in the market have the phenomenon of bulging at the joint of the pipe fitting and the pipe. The reason is that the electric hot melting pipe fitting connection needs to be heated to about 200 degrees of the melting point of polyethylene, the surface of the composite pipe fitting is hot melted with the inner surface of the pipe fitting, and the hot melting pipe fitting and the composite pipe fitting can be connected, but the surface of the hot melting pipe fitting, which is in contact with the composite pipe fitting, is also heated while the hot melting pipe fitting is heated, so that a steel wire reinforcing layer inside the composite pipe fitting is melted, the steel wire has tension, and the phenomenon of steel wire slippage can occur, thereby reducing the performance of the pipe fitting at the hot melting position, becoming the weakest point in the composite pipe fitting and the point which is easy to burst after bearing, the stability of the connecting position can be increased by winding a self-adhesive reinforcing belt at the connecting position, and the bearing capacity of the connecting position of the composite pipe fitting is improved. The PP protective layer can prevent the PE layer from being oxidized and polluted, and when the connection construction is carried out, the PP protective layer at the outer end of the self-adhesion reinforcing belt is peeled off to be directly connected with the hot-melt pipe fitting in an inserting mode, so that the connection efficiency is improved.
