Steel reinforced poly ethylene (PE) corrugated pipe and manufacturing equipment thereof

Abstract

The invention discloses a steel reinforced poly ethylene (PE) corrugated pipe and manufacturing equipment thereof. The corrugated pipe comprises a pipeline inner wall which is manufactured by spirally coiling a plastic plate strip and is characterized in that: at least one layer of steel mesh is wrapped on the outer side of the pipeline inner wall; a pipe wall PE layer is coated on the outer sideof the steel mesh; and a steel strip is fixed on the PE layer, and the PE layer is coated outside the steel strip. The invention has the advantages that: a pipeline is manufactured by spirally coiling the molded plate strip, so that a pipeline with an extremely large diameter can be manufactured; a large amount of plastic is not required to be extruded in the coiling process, so that energy consumption is reduced; the internal pressure bearing capability of the pipeline is improved by the steel mesh arranged in the pipeline wall; the pipeline wall PE layer is relatively thin; the external pressure bearing capability of the pipeline can be improved by the externally fixed steel strip; and the whole pipeline has low manufacturing cost and long service life, can be used as a water discharging pipe and a water supply pipe and is corrosion resistant.

Description

technical field [0001] The present invention relates to a polyethylene (PE) corrugated pipe with steel reinforcement on the pipe wall and equipment for manufacturing the PE corrugated pipe. Background technique [0002] Most of the existing steel belt corrugated pipes are extruded on the coiler, and the pipe wall is spirally rolled forward, and the steel belt is pressed into the pipe before the pipe is cooled. [0003] The hose coiling machine is usually used for forming large-diameter plastic pipes. For example, a hose coiling machine disclosed in Chinese invention patent 200510031522.9 includes a frame and an operation panel. The operation panel is uniformly distributed with pressing rollers and The guide rollers of the bracket, the pressing pair of rollers and the guide rollers of the bracket are arranged alternately to form a coaxial ring, and a protective cover is installed. There are also multi-layer installation holes evenly distributed radially between the protectiv...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above-mentioned extruded pipe strips are mainly that the finished product rate is not high, and a large amount of plastic needs to be extruded as the pipe wall, which requires the extrusion equipment to be very powerful, the processing equipment is expensive, and the energy consumption is high.
