Description

Abrasion-resistant and stretch-resistant steel skeleton reinforced thermoplastic composite continuous pipe

Technical Field

The utility model relates to the technical field of tubular product, especially, relate to a compound coiled tubing of compound of abrasion-resistant stretch-proof steel skeleton reinforcing thermoplastic.

Background

The composite pipe is formed by welding non-metal materials such as polyethylene, crosslinked polyethylene and the like inside and outside or based on a metal pipe and thermoplastic plastics, and has the advantages of the metal pipe and the non-metal pipe. The existing composite continuous pipe is made of plastic materials on the layer, when the pipe is laid when being dragged, friction is caused between the pipeline and the ground, the outer layer of the pipeline is abraded and broken, and the appearance of the pipeline is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the outer layer of the pipeline existing in the prior art is worn and broken to affect the beautiful defect, and providing a wear-resistant and stretch-proof steel skeleton reinforced thermoplastic composite continuous pipe.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the design is a compound coiled tubing of compound of wear-resisting stretch-proof steel skeleton reinforcing thermoplastic, including the inlayer, fixedly connected with reinforcing bar layer on the inlayer outer wall, the outside fixedly connected with parcel layer on reinforcing bar layer, the wear-resisting circle of fixedly connected with of parcel layer equidistance outside equidistance, it is adjacent clearance between the wear-resisting circle forms the ring channel.

Preferably, the wrapping layer is made of polybutylene material.

Preferably, the wear-resistant ring comprises a polyurethane layer, an elastic layer is fixedly connected to the inner side of the polyurethane layer, and a connecting layer is fixedly connected to the inner side of the elastic layer.

Preferably, the inner side of the inner layer is fixedly connected with a non-stick layer.

Preferably, the thickness ratio of the wrapping layer to the reinforcing steel bar layer is 2: 3.

The utility model provides a compound coiled tubing of compound of abrasion-resistant stretch-proof steel skeleton reinforcing thermoplastic, beneficial effect lies in: through the design that adopts parcel layer and inlayer, play the effect of the protection of parcel to the reinforcing bar layer, avoided the corrosion of reinforcing bar layer, the reinforcing bar layer increases the intensity and the anti stretchability of pipeline simultaneously, through the design that adopts wear-resisting circle, plays the effect of protection to the parcel layer, has strengthened the wearability of pipeline, prevents when laying the pipeline, the condition of wearing and tearing appears.

FIG. 1 is a schematic structural view of a wear-resistant stretch-proof steel skeleton reinforced thermoplastic composite coiled tubing of the present invention;

FIG. 2 is a front view of the abrasion-resistant stretch-proof steel skeleton reinforced thermoplastic composite coiled tubing shown in FIG. 1;

fig. 3 is a schematic structural view of the wear-resistant and stretch-proof steel skeleton reinforced thermoplastic composite coiled tubing wear-resistant ring of the present invention.

In the figure: the wear-resistant ring comprises a wear-resistant ring 1, a wrapping layer 2, a reinforcing steel layer 3, an inner layer 4, an annular groove 5, a polyurethane layer 6, an elastic layer 7, a connecting layer 8 and a non-stick layer 9.

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.

Example 1

Referring to fig. 1-3, a compound continuous pipe of compound of abrasion-resistant stretch-proof steel skeleton reinforcing thermoplasticity plastics, includes inlayer 4, fixedly connected with reinforcing bar layer 3 on the outer wall of inlayer 4, inlayer 4 is made for the PVC material, reinforcing bar layer 3's the outside fixedly connected with parcel layer 2, through adopting inlayer 4 and parcel layer 2's design, plays the effect of parcel protection to reinforcing bar layer 3, prevents that reinforcing bar layer 3 from being corroded rotten, and reinforcing bar layer 3's design has increased the intensity and the stretch-proofing ability of tubular product simultaneously.

The wrapping layer 2 is made of polybutylene material, the thickness ratio of the wrapping layer 2 to the reinforcing steel layer 3 is 2:3, the outer side of the wrapping layer is fixedly connected with wear-resistant rings 1 at equal intervals, a gap between every two adjacent wear-resistant rings 1 forms an annular groove 5, each wear-resistant ring 1 comprises a polyurethane layer 6, the inner side of each polyurethane layer 6 is fixedly connected with an elastic layer 7, each elastic layer 7 is made of rubber material, the inner side of each elastic layer 7 is fixedly connected with a connecting layer 8, each connecting layer 8 is made of abs resin material, the elasticity of the wear-resistant ring 1 is enhanced by the design of the elastic layer 7, so that when the pipe is bent, the wear-resistant rings 1 are prevented from cracking, the wear-resistant rings 1 are connected with the outer layer of the wrapping layer 2 at equal intervals, the outer part of the pipe is protected, the pipe is prevented from being abraded when being laid, and meanwhile, through the design of the annular groove 5, the number of the wear-resistant rings 1 is reduced, and material saving is facilitated.

Example 2

Referring to fig. 1, as another preferred embodiment of the present invention, on the basis of embodiment 1, the inner side fixedly connected with non-stick layer 9 of the inner layer 4 is made of teflon material, which prevents the medium from adhering to the inner wall of the pipe when the pipe transports the medium.
