PE composite pipeline reinforced by utilizing plastic body

Abstract

The invention discloses a PE composite pipeline reinforced by utilizing a plastic body. The invention comprises the following steps that a, a plastic body and a raw material are prepared for later use; b, after the step a is completed, a plastic spraying machine is used; c, after the step b is completed, then a steel wire is placed; d, after the step c is completed, and then a steel wire winding unit is utilized; e, after the step d is completed, and then winding of an inner core layer is carried out; and f, after the step e is completed, a reinforcing layer is wound. The spraying machine is used for spraying epoxy resin through a process which the plastic body is strengthened to be the PE composite pipeline, a steel wire winding unit cooperates to wind the steel wire, and the strength ofthe plastic body is increased while the water resistance of the plastic body is increased; and an inner core layer and a reinforcing layer can be arranged behind the steel wire, so that leveling of the steel wire is facilitated; and the whole wrapping property is improved by the modes of winding the steel wire along the longitudinal direction of the steel wire by 35 degrees through the inner corelayer, winding the reinforcing layer along the transverse direction of 35 degrees in a warp and weft winding, and popularization and use are facilitated.

Description

technical field [0001] The invention relates to the technical field of PE composite pipes, in particular to a PE composite pipe reinforced with a plastic body. Background technique [0002] PE is polyethylene. Generally, the application range of PE pipes for water supply pipes is below 40°C, and cannot be used for hot water pipelines. PE pipe is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. Certain types of chemicals can cause chemical corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). Plastic pipes in China are developing rapidly and their quality is constantly improving. At present, the plastic pipe industry mainly composed of polyvinyl chloride (PVC-U) pipes, polyethylene (PE) pipes and ...
