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,...

This paper focuses on the pipeline upgrading project of Zhengju New Materials North China Mine, and briefly describes the core background of the project to purchase UHMWPE pipeline on the basis of the original SRTP high-pressure pipeline cooperation and the differentiated working conditions of the mine. The project adopts the differentiated piping scheme that SRTP and UHMWPE pipes are adapted in different areas: SRTP steel wire mesh skeleton pipeline is responsible for low-abrasion and high-pressure transportation conditions such as conventional clean water and process backwater in mining area to ensure the stable pressure-bearing operation of the...

Recently, Zhengju New Materials officially completed the production of the high-performance UHMWPE pipe system for the G217 Expressway tunnel project in Xinjiang and successfully delivered the entire batch of pipes to the construction site. The products delivered were specifically designed to handle continuous mud and gravel transportation in extreme high-altitude environments.
