Technical Field

[0001] The utility model relates to the technical field of pipelines, and particularly relates to an explosion-proof and tensile-resistant polyethylene pipeline. Background Art

[0002] During the transportation of oil and gas, due to the particularity of the transportation medium, the inner wall of the transported metal pipeline will be corroded. Severe corrosion will cause the pipeline to perforate and leak, and even explode. The explosion of the metal pipeline will release huge impact energy and generate lethal explosion fragments. In some special application scenarios, such as offshore oil and gas exploitation, it is required that the transportation pipeline has excellent tensile resistance. Moreover, the better the pressure resistance of the transportation pipeline, the higher the transportation efficiency of oil and gas. In summary, it is very necessary to develop a transportation pipeline with corrosion resistance, pressure resistance, tensile resistance and explosion protection. Content of the Utility Model
