Inner wall pre-repairing pipeline for petroleum transportation

Abstract

The invention discloses an inner wall pre-repairing pipeline for petroleum transportation, and belongs to the field of pipelines. According to the inner wall pre-repairing pipeline for petroleum transportation, a pre-repairing undulating ring layer is arranged, and can deform in the petroleum transportation process, consequently, on the one hand, the inner wall of a pipeline body is effectively prevented from easily crushing due to long time extrusion of petroleum, on the other hand, in the deformation process, a pipeline repairing agent in an overflow rod and graphene in an overflow powder layer continuously overflow and condense on the inner wall of the pipeline body to form a pre-repairing layer, the pre-repairing effect of cracks on the inner wall of the pipe body is better so that thesurface of the pipe body can be blocked in time when cracks are generated due to long-term use, meanwhile, the pre-repairing layer doped with graphene powders has certain lubricity so that the pre-repairing layer can maintain high stability under the condition of the deformation friction of the pre-repairing undulating ring layer and cannot be prone to damaging due to friction, and thus, the pre-repairing layer can pre-repair the inner wall of the pipeline body for a long time.

Description

technical field [0001] The invention relates to the field of pipelines, in particular to an inner wall pre-repair pipeline for petroleum transportation. 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 for the completion of oil loading and unloading and transportation Task. [0003] 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. [0004] The pipes of o...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the object of the present invention is to provide a pre-repaired inner wall pipeline for oil transportation. Through the setting of the pre-repaired undulating ring layer, the pre-repaired undulating ring layer will be deformed during the oil transportation process. On the one hand, it effectively protects the inner wall of the pipeline from being easily squeezed by oil for a long time, and on the other hand, during the deformation process, the pipeline repair agent inside the spill rod and the graphene in the spilled powder layer continue to overflow and condense on the pipeline. The inner wall of the main body forms a pre-repair layer, which has a better effect on the prevention and repair of cracks on the inner wall of the pipeline body, so that the surface can be blocked in time when cracks occur on the surface after long-term use. At the same time, the pre-repair layer mixed with graphene powder, It has a certain lubricity, so that it can maintain high stability under the condition of pre-repairing the deformation and friction of the undulating ring layer, and is not easy to be damaged by friction, so that it can play a long-term preventive and repairing role on the inner wall of the pipeline body
