The invention discloses a steel strip composite pipe with a flaring, which is used for improving the flaring strength of the steel strip composite pipe and belongs to the technical field of pipes.

Background

The steel belt pipe is also called as a steel belt reinforced polyethylene spiral corrugated pipe for buried drainage, and is a novel plastic buried drainage pipe; the double-wall spiral corrugated pipe is a double-wall spiral corrugated pipe which takes high-density polyethylene as a matrix, takes a wave shape formed by a steel belt with the surface coated with bonding resin as a main supporting structure, and is wound and compounded with polyethylene materials into a whole, and is called as a steel belt reinforced PE spiral corrugated pipe, and is called as a steel belt pipe for short.

The length of steel band pipe has certain limit usually, need connect many steel band pipes when using and use, present steel band pipe sets up the flaring so that connect at the tip of steel band pipe body usually, but the flaring hardly sets up the steel band like steel band pipe and strengthens its intensity, so the intensity of flaring is general relatively poor, and the flaring is comparatively serious as connecting the position wearing and tearing, and shock resistance can not be strong enough, leads to the flaring very easy damage, and life is shorter.

Disclosure of Invention

The invention aims to: the steel strip composite pipe with the flaring is convenient to connect by arranging the flaring, and the flaring has excellent wear resistance, impact resistance, high strength and mechanical property and long service life.

The technical scheme adopted by the invention is as follows:

in order to achieve the purpose, the invention provides a steel strip composite pipe with a flaring, which comprises a steel strip composite pipe body and a flaring body, wherein the flaring body is connected with the steel strip composite pipe body through a flaring connecting part, the flaring body comprises an anticorrosive layer, a flaring base pipe, a buffer layer, a reinforcing layer and a wear-resisting layer which are sequentially arranged from inside to outside, and the outer surface of the flaring body is also provided with a convex edge.

Preferably, the steel strip composite pipe body comprises an outer pipe, a steel strip and an inner pipe which are sequentially arranged from outside to inside.

Preferably, the arrangement direction of the convex ribs is crossed with the axial direction of the flaring body, and the crossing angle is 30-60 degrees.

Preferably, the anticorrosive layer material is tetrafluoroethylene.

Preferably, the buffer layer material is a polyurethane thermoplastic elastomer.

Preferably, the reinforcing layer is made of steel wire mesh or glass fiber.

Preferably, the wear-resistant layer is made of polysiloxane modified ultra-high molecular weight polyethylene.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

the flaring body is provided with the anti-abrasion layer on the outer side, the anti-abrasion layer is arranged on the outer side of the flaring body, the service life of the flaring body is prolonged by matching with the convex edges, when the flaring body is subjected to external pressure or impact force, the high-elasticity buffer layer can absorb and buffer the acting force, so that the impact force acting on the flaring body is reduced, meanwhile, the high strength of the reinforcing layer can prevent the flaring body from being damaged when the flaring body is subjected to the external action, the corrosion of fluid in a pipe to the flaring body can be effectively reduced by the inner anti-corrosion layer, and the flaring body has excellent anti-abrasion performance, impact resistance, high strength and mechanical performance.
