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.

SRTP (steel wire mesh skeleton plastic composite pipe) is a new type of high-pressure composite pipe, which is the core carrier for high-pressure conveying in industrial and municipal fields. Composed of a "plastic-steel wire-plastic" three-layer composite structure, SRTP pipe uses high-strength steel wire winding as the reinforcement matrix and HDPE material for inner and outer layers, integrating the advantages of pressure resistance and corrosion resistance. With a working pressure range of 0.6-3.5MPa and elongation at break ≥350%, it is widely applied in industrial high-pressure transportation (chemical reagents, mining pulp, metallurgical cooling water) and municipal high-pressure scenarios...
