Abstract

The embodiment of the invention discloses a pipeline assembly and a construction method of the pipeline assembly, and belongs to the technical field of oil and gas transmission. The pipeline assembly comprises a sleeve and a pipeline. The pipeline is located in the sleeve, and a hollow cavity is formed between the pipeline and the sleeve; the hollow cavity is filled with an anti-corrosion material, and the anti-corrosion material is used for reducing the corrosion speed of the pipeline; the insulating supporting blocks are arranged on the outer surface of the pipeline at intervals and used for protecting pipeline installation. The anti-floating supporting block is arranged on the upper half side pipeline close to the gravity center position of the pipeline and used for preventing the pipeline from floating. According to the embodiment of the invention, the stability and durability of the pipeline are improved, so that the service life of the pipeline is prolonged, and the intrinsic safety of the pipeline is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of oil and gas transportation, and in particular to a pipeline assembly and a construction method for the pipeline assembly. Background technique [0002] When buried pipelines cross railways and highways, casings are generally used to protect the pipelines, so that the pipelines are not affected by external dynamic loads or soil pressure. [0003] In the related art, steel pipes or reinforced concrete pipes are generally used for casing pipes, insulating supports are provided between the casing pipes and pipes, and both ends of the casing pipes are sealed. There is an exhaust pipe at one end of the casing, and the annular space between the casing and the pipe is not filled with medium. The protection method of installing a sacrificial anode on the pipe is used to prevent corrosion of the pipe. [0004] However, the constraint of the pipeline in the above-mentioned related art is...
