Addressing the dual challenges of persistent high corrosion and high fatigue in pipelines used in chemical, mining, and marine engineering, this paper systematically elaborates on a comprehensive protection solution for steel-lined composite pipes made from Zhengju New Materials. The paper focuses on analyzing the material properties of the UHMWPE and POE linings, detailing the core role of steel mesh reinforcement and fixing processes in resolving engineering challenges such as negative pressure shrinkage and thermal expansion delamination. Furthermore, it compares the formulation and applicable cost conditions of three-stage external protection solutions: uniform hot-dip lining, conventional resin coating,...
