Abstract

The invention discloses an oil and gas multiphase-flow multi-cavity intelligent heat preservation pipeline structure and a construction method, and relates to the technical field of pipelines. The structure is formed through sequential connection of three pipelines through a GFRP buckling-prevention energy dissipation damper, axes of the three pipelines are connected in sequence to form an equilateral triangle, each pipeline comprises a pipeline single body and a whole type joint, each pipeline single body comprises an outer layer GFRP round pipe, an inner layer GFRP round pipe, a self-compaction fine aggregate concrete layer and an annular heat transfer plate, an outer layer GFRP round pipe reserved bolt hole and a heat conduction pipe mounting hole are formed in the outer wall of each outer layer GFRP round pipe, the heat conduction pipe mounting holes are connected with temperature control devices through steel anchor racks, two pipeline single bodies are connected through the wholetype joints, and concrete pouring holes and exhaust holes are formed in the outer walls of the whole type joints. The oil and gas multiphase-flow multi-cavity intelligent heat preservation pipeline structure and the construction method solve the problems that a traditional pipeline is small in diameter, poor in stability and anti-permeability, low in conveying efficiency, single in conveying manner, and poor in heat preservation property of conveying media in the high and cold area.

Description

Technical field: [0001] The invention relates to the technical field of pipelines, in particular to an oil-gas multiphase flow multi-cavity intelligent heat preservation pipeline structure and a construction method. 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 standards, and ...
