In this paper, based on the actual hydraulic conditions of mine water conveyance site, the hydraulic operation differences among steel pipes, ordinary HDPE pipes and SRTP steel mesh skeleton pipes are compared and analyzed from five practical operation and maintenance pain points: pipe wall friction resistance, pipe deformation, interface pressure loss, water hammer tolerance and long-term scaling. This paper shows that SRTP pipeline relies on steel-plastic composite structure, taking into account the smoothness of water delivery and structural rigidity, with lower pressure loss and more stable operation, which is more suitable for high-pressure long-distance water delivery...

Based on the real working conditions of the mine, this paper explains the applicable scenarios and selection logic of SRTP high-pressure pipeline and UHMWPE wear-resistant pipeline. SRTP is suitable for conventional working conditions such as high-pressure water conveyance and circulating water in mines, and has strong stability. UHMWPE specializes in treating high wear scenes such as tailings and mud, which greatly reduces the operation and maintenance costs. Practical Q&A is attached to the article, which provides a reference for mine pipeline selection and pipe network transformation.

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,...
