Problems solved by technology

[0002] Pipes are widely used in water supply and drainage, petrochemical and other fields, but common plastic pipes such as PE and PP have low compressive strength, and cannot meet the demand in some high-pressure environments
Increasing the wall thickness of the pipe can increase the compressive strength of the pipe, but this method will greatly increase the weight and cost of the pipe
Composite pipe is an improved pipe based on plastic pipe that is widely used now, but its strength and compressive performance still cannot meet the requirements in some specific occasions.

Abstract

The invention discloses a reinforced composite pipeline. The composite pipeline is sequentially provided with a polyethylene fiber outer layer, a plastic resin layer, a steel mesh reinforcing layer and a polyethylene inner layer from outside to inside, the polyethylene fiber outer layer is made of mesh cloth and a polyethylene material in an co-extruded mode, the steel mesh reinforcing layer is ofa mesh structure formed by longitudinal steel wires and transverse steel wires in a staggered mode, and the plastic resin layer and the polyethylene inner layer which are located on the inner side and the outer side of the steel mesh reinforcing layer penetrate through a through hole of the steel mesh reinforcing layer and then are melted into a whole. According to the reinforced composite pipeline, the pipeline outer layer adopts the polyethylene fiber outer layer, breaking or frost crack of the pipeline can be effectively prevented, the tensile strength of the pipeline is reinforced, the steel mesh reinforcing layer is arranged in the middle of the pipeline, the through hole and a protrusion are arranged on the steel mesh reinforcing layer, thus the layers of the pipeline are combined more closely, and the load bearing ability is improved.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a reinforced composite pipe. Background technique [0002] Pipes are widely used in water supply and drainage, petrochemical and other fields, but common plastic pipes such as PE and PP have low compressive strength, and cannot meet the demand in some high-pressure environments. Increasing the wall thickness of the pipe can increase the compressive strength of the pipe, but this method will greatly increase the weight and cost of the pipe. Composite pipe is an improved pipe based on plastic pipe which is widely used now, but its strength and compressive performance still cannot meet the requirements in some specific occasions. Contents of the invention [0003] The object of the present invention is to provide a reinforced composite pipeline to solve the above problems. [0004] The present invention is achieved through the following technical solutions: [0005] A reinforced ...
