Overall type steel belt vertical rib composite tube and manufacturing method thereof

Abstract

The invention relates to an overall type steel belt vertical rib composite tube and a manufacturing method thereof. A vertical rib steel belt of the composite tube is provided with evenly-distributed meshes, meanwhile, the outer surface of the steel belt is coated with even adhesive resin, and the adhesive resin and the steel belt form a stable interpenetration adhesive structure; the steel belt coated with the adhesive resin is used for producing abnormal-shaped strips with vertical ribs, and the abnormal-shaped strips are used for producing the overall type steel belt vertical rib composite tube through spiral winding and welding; by means of the abnormal-shaped strips and tubular products which are produced in the manner, the stability of the overall structure can be guaranteed, and the service life of the tubular products is prolonged; and coating of the steel strips with the adhesive resin is achieved through a specific opening die, and the steel strips need to be heated to the required temperature before coating of the adhesive resin. By means of the overall type steel belt vertical rib composite tube and the manufacturing method, the problems that the steel belt vertical ribs and outer layer polyethylene are layered, and consequently the vertical ribs are toppled and fall, and a polyethylene protection layer is cracked are solved.

Description

technical field [0001] The invention relates to an integral steel strip vertical rib composite pipe and a manufacturing method thereof, belonging to the technical field of steel-plastic composite pipe design and production. Background technique [0002] Pipes made of various plastics and metal or non-metallic reinforcing materials are widely used. With the increasing application of composite pipes and the growth of application time, the problem of structural delamination between different materials has received more and more attention. [0003] Steel skeleton plastic composite pipe (ZL94104509.9) uses welded steel mesh skeleton and plastic to form an interpenetrating structure to ensure the long-term stability of the pipe structure. The steel strip reinforced polyethylene spiral corrugated pipe adopts the outer layer of galvanized steel strip coated with adhesive resin, so that the reinforced steel strip and the inner and outer polyethylene plastic are integrated to ensure ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an integral steel-belt vertical-rib composite pipe and its manufacturing method to solve the problem of delamination of the steel-belt vertical rib and the outer layer of polyethylene, which leads to the collapse of the vertical rib and the rupture of the polyethylene protective layer. problem, improve the vertical rib stability of steel belt vertical rib composite pipe
