Abstract

The invention discloses a petroleum transportation pipeline. The petroleum transportation pipeline comprises a pipe body, wherein an anti-static layer is arranged on the inner wall of the pipe body, and a heat insulation layer is arranged on the outer wall of the pipe body; a buffer layer is arranged on the outer wall of the heat insulation layer; a plurality of joints are arranged on the pipe body; dredge pipes connected with a gas source are arranged outside the pipe body in parallel; a purging pipe communicated with each joint is arranged on the corresponding dredge pipe; and a purging valve is arranged on each purging pipe. According to the invention, the problem of blockage of powdery materials in pipeline transportation is solved, high-pressure purging wind can be charged to purge in the case that the pipeline is blocked through arranging the dredge pipes in parallel, and the petroleum pipeline is simple in structure, and simple, convenient and fast to operate; and meanwhile, the problem of pipeline blockage due to cold is further solved through arranging the heat insulation layer. In addition, an anti-static coating is specially prepared, so that the petroleum pipeline has an excellent anti-static capacity without the need of grounding; and the petroleum pipeline is high in anti-static capacity, high in petroleum corrosion-resistant effect, and capable of being protected from static trouble for a long time.

Description

technical field [0001] The invention relates to the field of petroleum equipment, in particular to a petroleum transportation pipeline. Background technique [0002] In the process of oil extraction, petroleum pipelines will inevitably be used. The existing petroleum pipelines have the following defects: First, due to the high wax content in petroleum and the high oil concentration, it often causes difficulties in oil pipeline transportation, especially In the cold season, it is necessary to heat the oil pipeline to solve the problem of difficult oil transportation; second, during the transportation of oil, occasionally the pipeline will be blocked due to the impurities in the oil and the viscosity of the oil itself. Once the pipeline is blocked, it will As a result, oil cannot be transported normally, and manual dredging is required. If the pipeline is shorter and thicker, it will be easier to dredge. If the pipeline is longer and thinner, the dredging process will become v...
