The Application and Study of PE Pipeline for Gas Industry

This paper comments on the research of PE pipeline global properties, application and fast fracture, the optimal plan of pipeline diameter which inserts PE pipeline is illustrated during repair steel pipeline, the flow parameters and pressure conditions are determined, and the fracture of PE pipeline is analyzed.With above results, the loading pressuue of PE pipeline throws obstacles in the application on long-distance transportation pipeline.Therefore, developing PE composite structure materials with high loading pressure is a way to simulate PE pipeline instead of steel pipeline.
