AI Technical Summary

Technical Problem

Existing metal-wound reinforced thermoplastic pipes generally have poor material properties, and the easily removable protective structures on both sides of the pipe body can easily allow debris to enter, increasing the difficulty of cleaning.

Method used

It adopts a multi-layer structure design, including an inner layer, an outer layer, a metal woven mesh, and an aramid fiber layer. The outer and inner layers resist external pressure and internal pressure respectively, and detachable rubber protective sleeves are set on both sides. The inner wall of the protective sleeve is equipped with a conical block to block debris.

Benefits of technology

It improves the compressive strength and corrosion resistance of the pipe body, simplifies the maintenance and cleaning process, reduces maintenance costs, and ensures the cleanliness and stable operation of the pipeline interior.
