Abstract

The invention provides a high-strength dual-wave pipeline and a preparation method thereof. According to the high-strength double-wave pipeline and the preparation method thereof, the prepared high-strength double-wave pipeline is high in ring stiffness, high in corrosion resistance and more reasonable in bearing structure. The high-strength double-wave pipeline comprises inner-layer polyethylene,outer-layer polyethylene, a hole net steel belt, adhesive resin, anti-corrosion layers, reinforcing belts and thermal contraction belts, and the hole net steel belt is arranged above the inner-layerpolyethylene; the cross section of the hole net steel belt is provided with M-shaped double-wave peaks, the outer-layer polyethylene is arranged above the hole net steel belt in an attached mode, theadhesive resin is arranged in the outer-layer polyethylene, gaps are formed between the double-wave peaks, and anti-corrosion layers, reinforcing belts and thermal contraction belts are further arranged between the gaps; and the anti-corrosion layers are arranged to be tightly attached to the outer-layer polyethylene, the reinforcing belts and the thermal contraction belts are arranged outside theanti-corrosion layers, and the thermal contraction belts are arranged above the reinforcing belts.

Description

technical field [0001] The invention relates to the field of corrugated pipes, in particular to a high-strength double-wave pipe and a preparation method thereof. Background technique [0002] Each composite layer of the steel belt corrugated pipe is carried out in the molten state of plastic, which is completely different from the secondary melting molding of the winding pipe (hollow wall pipe), so the layers are completely bonded and the fastness is very high. Through special pretreatment on the surface of the steel strip, the anti-corrosion ability of the steel and the adhesion between the steel and the plastic can be enhanced to improve the peel strength. When the plastic raw material is fully melted, it is wound and formed, and the overall structure of the pipe is firm and reliable. Due to the use of special materials and processes, both the anti-corrosion problem of the steel plate and the adhesion between the steel plate and the PE material are solved, so that the se...
