Description

Novel glass fiber reinforced plastic corrosion-resistant pipe

Technical Field

The utility model relates to a glass steel accessory technical field specifically says a novel glass steel corrosion resistant pipe for supporting, connect and use.

Background

It is known that in the field of cultivation, construction and offshore platform erection, steel pipes or metal pipes are generally required to be supported and fixed, but the corrosion resistance and the oxidation resistance of the existing metal pipes are poor, so that pipelines are easily corroded and damaged after long-term use, and the service life of the platforms is seriously influenced.

According to the defects in the prior art, technical personnel in the industry improve the forming of the glass fiber reinforced plastic pipe by adopting a glass fiber reinforced plastic forming mode, and replace a metal pipe with the glass fiber reinforced plastic pipe to improve the defects in the prior art, but in practical application, the fact that the strength of the glass fiber reinforced plastic pipe is greatly different from that of the metal pipe, the glass fiber reinforced plastic pipe is easy to break when bearing or being used for a long time, and potential safety hazards exist.

Disclosure of Invention

Problem to prior art existence, the utility model aims at providing a novel glass steel corrosion resistant pipe can solve the above technical problem that meets at present.

In order to achieve the purpose, the specific scheme is as follows: a novel glass fiber reinforced plastic corrosion-resistant pipe comprises a metal pipe main body, wherein an inner rust-proof layer is sprayed on the inner wall of the metal pipe main body; the outer protective layer is arranged on the outer side of the metal pipe main body and comprises a circle of fiber tows arranged on the periphery of the metal pipe main body, and the fiber tows are attached to the metal pipe main body through polyurethane and form a smooth outer surface on the outer surface.

The metal pipe main body is provided with a plurality of strip-shaped bulges on the outer surface, and the strip-shaped bulges are uniformly distributed on the metal pipe main body.

The metal pipe main body is provided with a plurality of spiral bulges on the outer surface, and the spiral bulges are arranged on the outer surface of the metal pipe main body in a surrounding way.

The metal pipe is a steel pipe.

The fiber tows are glass fiber tows.

The utility model has the advantages that: through the improvement, the product of the utility model is provided with a circle of fiber bundles by coating the outer surface of the metal pipe, and the fiber bundles are laminated and coated on the outer surface of the metal pipe through polyurethane; furthermore, the utility model discloses still can set up strip arch or spiral at the surface of tubular metal resonator and change the arch, through this kind of design, can strengthen the laminating ability on polyurethane and tubular metal resonator surface. To sum up, the utility model discloses structural design is simple, and is novel, and corrosion resisting property is high, is the novel glass steel corrosion resistant pipe of an ideal.
