Tube-framework plastic composite tube and producing process thereof

Abstract

The invention discloses a tube-framework plastic composite tube and a producing process thereof. The structure of the tube-framework plastic tube comprises a tube body, wherein the tube body comprises an inner pressure tube, an entwining structure wall and an outer wrapping layer in sequence from inside to outside; the inner pressure tube is an integrally formed thin-wall tube; the wall of the inner pressure tube is evenly, externally and spirally wound with the entwining structure wall; and the outer wrapping layer evenly wraps the outer sides of the inner pressure tube and the entwining structure wall. Besides, a layer of glue is evenly sprayed to the external surface of the entwining structure wall; and the entwining structure wall is a belt-shaped special-shaped profile or a hollow tubular profile. The tube provided by the invention has the characteristics of high ring stiffness, high inner pressure bearing capability, low cost and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of pipe materials, in particular to a plastic composite pipe with a pipe skeleton and a production process thereof. Background technique [0002] With the development of science and technology, pipes are playing an increasingly important role in all walks of life. The pipe wall of traditional pipes is a single-layer structure, which can withstand limited pressure. If you want the pipe to withstand greater pressure, you need to increase the pipe. The thickness of the wall will lead to a series of problems such as more materials, heavy weight, high product cost and low production efficiency. Contents of the invention [0003] One of the objectives of the present invention is to provide a plastic composite pipe with a pipe skeleton with high ring rigidity, high pressure bearing, high production efficiency and low cost. [0004] The second object of the present invention is to provide a production process for...
