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. The plastic composite pipe comprises an outer pipe and an inner pipe. Arc grooves are formed in the inner side of the outer pipe. Arc protruding parts are arranged on the outer side of the inner pipe. The arc protruding parts are arranged in the arc grooves. The thickness ratio of the outer pipe and the inner pipe is 1:1. According to the plastic composite pipe, through the inner pipe made of a polypropylene material, the composite pipe is very high in plasticity and has certain flexibility, the high pressure in the water pipe can be resisted, and the phenomenon of pipe blasting is effectively prevented; the manufacturing cost of the composite pipe is reduced due to the fact that the outer pipe is made of a polyvinyl chloride material; and the arc protruding parts are designed on the inner pipe, and therefore the inner pipe and the outer pipe are perfectly bonded together.

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...
