AI Technical Summary

Technical Problem

When subjected to loads such as internal pressure, existing perforated steel strip composite pipes are prone to localized damage and crack propagation in stress concentration areas, affecting performance and lifespan.

Method used

Main bearing holes and auxiliary dispersion holes are set on the steel plate mesh layer. The main bearing holes and auxiliary dispersion holes are evenly distributed. The auxiliary dispersion holes are distributed around the main bearing holes. The stress is dispersed by the auxiliary dispersion holes. Combined with the molten filling of the plastic layer, the interlayer bonding force and overall mechanical properties are enhanced.

Benefits of technology

It effectively inhibits crack propagation, improves the uniformity of internal stress in the plastic layer, reduces the risk of delamination, enhances interlayer bonding, and improves the reliability and overall performance of the pipe.
