Problems solved by technology

[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.

Embodiment 1

[0030] Such as figure 1 As shown, the winding structure wall 2 is a strip-shaped profile.

Embodiment 2

[0032] Such as figure 2 As shown, the winding structure wall 2 is a hollow tubular profile made of metal or non-metal.

[0033] Such as Figure 4 As shown, the production process of the pipe skeleton reinforced plastic composite pipe of the present invention is characterized in that it comprises the following steps:

[0034] ①The extruder extrudes the integrally formed thin-walled tube, which is vacuum shaped and cooled to form the internal pressure tube 1;

[0035] ② Use a mold to support the tube body of the internal pressure tube 1 into a circle, and its out-of-roundness is controlled within 1.5%, and a layer of reinforcing mesh or reinforcing wire coated with glue inside and outside is wound on the outer surface of the internal pressure tube 1;

[0036] ③The winding structure wall 2 is spirally wound on the outside of the reinforcement mesh or reinforcement wire according to a certain pitch;

[0037] ④ extruder extruding plastic material in molten state, the plastic ma...

Abstract

The invention discloses a tube-framework strengthened plastic composite tube and a producing process thereof. The structure of the tube-framework strengthened plastic composite tube comprises a tube body, wherein the tube body comprises an inner pressure tube; the inner pressure tube is an integrally formed thin-wall tube; the outer surface of the inner pressure tube is wound with a strengtheningdevice; the outer side of the strengthening device is evenly and spirally wound with an entwining structure wall; and an outer wrapping layer evenly wraps the outer sides of the strengthening device and the entwining structure wall. The strengthening device is a strengthening net or a strengthening wire; and the strengthening net or the strengthening wire is formed by steel wires or glass fibers.Besides, a layer of glue is evenly sprayed to the outer 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 pipe skeleton reinforced plastic composite pipe and its production process. 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 pipe skeleton reinforced plastic composite pipe 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 f...
