Abstract

The invention discloses an efficient repairing technology of an oil transporting pipeline, and relates to the technical field of pipeline repairing. The technology comprises the following steps that S1, the two sides of a pipeline leakage position of the pipeline are sleeved with sealing rings respectively; S2, the pipeline is sleeved with a mold pipe, an injection pipe is arranged on the mold pipe, the inner wall of the mold pipe makes tight contact with the sealing rings, and the inner wall of the mold pipe, the outer wall of the pipeline and the sealing rings form a sealed molding cavity; S3, a sealant is injected into the molding cavity through the injection pipe until the molding cavity is filled fully, and the mold pipe is taken down after the sealant is solidified. The efficient repairing technology has the advantages that operation is convenient, the formed sealed structure stability is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of pipeline repair, and more specifically relates to an efficient oil pipeline repair process. Background technique [0002] Oil pipelines (also called pipelines, pipelines) are composed of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the process flow, designed and installed as a complete pipeline system to complete oil unloading and transportation Task. The oil pipeline system, that is, the pipeline system used to transport oil and petroleum products, is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. For transportation equipment, compared with railway and highway oil transportation, which are also land transportation methods, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. The pipes of oil pipelines are generally ste...
