Problems solved by technology

However, the hardness of the composite pipe is too strong, and when it needs to be bent, it can only be realized by adding a joint, which is extremely inconvenient to operate, and aluminum is used as the inner pipe, which costs a lot

Embodiment Construction

[0014] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments.

[0015] A plastic composite pipe, comprising an outer pipe 1 and an inner pipe 2, the inner side of the outer pipe 1 has an arc groove 3, the outer side of the inner pipe 2 has an arc protrusion 4, and the arc protrusion 4 is in the arc recess In the groove 3, the thickness ratio of the outer tube 1 to the inner tube 2 is 1:1, the arc radius of the arc raised part 4 is 1 / 4 of the thickness of the inner tube 2, and the outer tube 1 is made of polyvinyl chloride material. As, the inner tube 2 is made of polypropylene material.

[0016] The present invention combines the outer tube 1 and the inner tube 2 perfectly through the design of the arc groove 3 on the outer tube 1 and the arc protrusion 4 on the inner tube 2, and the outer tube 1 is thicker than the inner tube 2, which can ensure The pressure resistance of the pipe, the inner pipe 2 is made ...

Abstract

The invention discloses a plastic composite pipe which comprises an outer pipe and an inner pipe. An arc groove is formed in the inner side of the outer pipe, an arc projection is arranged on the outer side of the inner pipe and placed in the arc groove, and the thickness ratio of the outer pipe to the inner pipe is 1:1. The inner pipe is made of polypropylene materials, so that the composite pipe is high in plasticity, has a certain flexibility and can resist high pressure in a water pipe, pipe burst is effectively prevented, the outer pipe is made of polyvinyl chloride materials, the manufacturing cost of the composite pipe is reduced, and the inner pipe and the outer pipe are perfectly adhered together by designing the arc projection on the inner pipe.

Description

technical field [0001] The invention relates to a plastic pipe, in particular to a plastic composite pipe. Background technique [0002] At present, the application of plastic pipes is more and more extensive, and has been involved in various fields such as construction, engineering, and daily use. At present, the plastic pipes in the prior art are divided into single-layer and double-layer plastic pipes, and the double-layer plastic pipes, such as the patent No. CN101979908A's invention patent "composite plastic pipe", the inner wall is made of aluminum, and the outside is made of PE resin. This plastic pipe not only retains the characteristics of plastic pipes such as anti-corrosion and anti-aging, but also increases the overall steel strength. However, the hardness of the composite pipe is too strong, and when it needs to be bent, it can only be realized by adding joints, which is very inconvenient to operate, and the aluminum material is used as the inner pipe, so the pr...
