Description

Technical field: [0001] The invention relates to the technical field of pipelines, in particular to a structural system and a construction method of an oil-gas multiphase leveling cavity and heat preservation composite pipeline. Background technique: [0002] Conventional long-distance pipelines are mostly round steel pipes and reinforced concrete round pipes, with diameters ranging from 0.5 meters to 1.5 meters. One end adopts the form of an enlarged head, and the connection between the pipes is realized through the head. The liquid is transported in the steel pipe all the year round, and it is easy to rust. Long-term erosion will reduce the effective thickness of the pipe wall, reduce the rigidity of the pipe wall, and local buckling will easily occur under the pressure of the soil and the outside world. At the same time, due to the erosion of the inner wall by the liquid in the pipeline, there are more and more impurities. It is difficult to meet the quality inspection st...
