Abstract

The invention relates to a wear-resistant steel skeleton plastic composite pipe, a manufacturing method thereof and a plastic composite mold, wherein the inner layer of the wear-resistant steel skeleton plastic composite pipe is a wear-resistant layer to solve the wear-resistant problem of the composite pipe, and the outer layer is high-density polyethylene The anti-corrosion layer ensures the external anti-corrosion properties of the pipeline, and the middle layer is a reinforced steel wire welding skeleton layer to ensure the overall strength of the pipe. The composite pipe realizes the composite of the wear-resistant layer, the high-density polyethylene layer and the reinforced skeleton layer through special inner and outer plastic composite molds and forms an interpenetrating structure to ensure the structural stability of the pipe.

Description

technical field [0001] The invention relates to a wear-resistant steel frame plastic composite pipe. Specifically, the inner layer of the steel frame plastic composite pipe is a wear-resistant layer, and the pipe can be used in fields with special requirements for wear resistance. The invention also relates to a manufacturing method and a manufacturing device of the wear-resistant pipe. Background technique [0002] Wear-resistant pipelines are a very important market segment in the pipeline industry, mainly used for the transportation of pneumatic, pumped slurry and other materials. Due to the characteristics of high hardness, fast flow rate, and large flow rate of the conveying medium, the wear-resistant pipe can effectively reduce the speed at which the conveying medium continuously impacts, wears, and corrodes the pipe wall for a long time, which causes the pipe to fatigue and gradually wear out. Research on wear-resistant pipelines has not stopped at home and abroad. ...
