Problems solved by technology

However, due to the different coefficients of pressure resistance and thermal expansion of plastic pipes and metal pipes, the inner plastic pipe is prone to deformation during processing, storage, transportation and use. It is difficult to connect between the pipes, which will cause leakage between the pipes due to the deformation of the pipe joints during use; on the other hand, the gaps between the plastic pipes and the metal pipes will be uneven in size or even fall off, and the corrosive medium is easy to enter during use. Corrosion occurs due to the interlayer gap, and at the same time, the plastic pipe in the large gap will also be damaged due to excessive local force due to the inability to transmit the pressure to the metal pipe

Abstract

The invention discloses an enhanced metal plastic composite pipe. The enhanced metal plastic composite pipe comprises an outer layer metal pipe body (1) and an inner layer plastic pipe body (2) which are combined, wherein the inner wall of the outer layer metal pipe body (1) is connected with the side faces of a plurality of metal wires (3), the space between every two adjacent metal wires (3) is smaller than or equal to 300 mm, and the metal wires (3) are embedded in the plastic pipe body (2). The metal wires can have the effect for enhancing the connecting force between the metal pipe body and the plastic pipe body, the metal pipe body and the plastic pipe body can be connected closely, and the disengagement phenomenon is avoided; deformation of the plastic pipe body can also be prevented, various problems caused by deformation of the plastic pipe body are avoided, the reliability of the metal plastic composite pipe is enhanced, and service life is prolonged.

Description

technical field [0001] The invention relates to an industrial and civil composite pipe, in particular to a reinforced metal-plastic composite pipe which has good bonding quality, can prevent plastic pipe deformation, and has the advantages of high strength and rigidity of metal pipes and corrosion resistance of plastic pipes. Background technique [0002] Metal pipes include carbon steel pipes, stainless steel pipes, etc., which have the advantages of high strength and good rigidity, but the disadvantages are that they are easy to rust, scale, etc., and have poor corrosion resistance. Plastic pipe is a product made of synthetic resin and additives through melt molding, including hard polyvinyl chloride pipe (PVC-U), high-density polyethylene pipe (PE-HD), cross-linked polyethylene pipe (PE-X), Random copolymer polypropylene pipe (PP-R), polybutene pipe (PB), engineering plastic acrylonitrile-butadiene-styrene copolymer (ABS), etc. The main advantages of plastic pipes are co...
