Description

Technical Field

[0001] The utility model relates to the technical field of petroleum pipelines, in particular to a petroleum transportation pipeline capable of preventing wax blockage. Background Art

[0002] Pipeline transportation is a mode of transportation that uses pipelines as a means of transportation to transport liquid and gaseous materials over long distances. It is a special mode of transportation that transports oil, coal and chemical products from the production site to the market. It is a special component of trunk transportation in the unified transportation network. When oil is transported on the inner wall of the oil pipeline for a long time, paraffin crystals are easily produced, which is not conducive to the transportation of oil.

[0003] The existing authorized patent number is CN 213871700 U, which is an oil transportation pipeline for preventing wax blockage. The pipeline comprises a right-angle elbow, one end of which is fixedly sleeved with an oil inlet pipe, the other end of which is fixedly sleeved with an oil outlet pipe, a wax retaining ring is fixedly installed on the surface of the right-angle elbow, an inner wall of the wax retaining ring is provided with an opening, a protective shell is fixedly installed on one side of the wax retaining ring and located on the surface of the right-angle elbow, a torsion spring is fixedly installed on the inner wall of the protective shell, an oil retaining sheet is fixedly installed on the surface of the torsion spring, one end of a shock-absorbing spring is fixedly installed on the inner wall of the right-angle elbow, a shock-absorbing sheet is fixedly installed on the other end of the shock-absorbing spring, a replacement device is fixedly installed on one end of the protective shell and located on the surface of the right-angle elbow, and the replacement device comprises an outer shell, and an opening is provided inside the outer shell.

[0004] The above-mentioned equipment has a reasonable structure. The paraffin crystals and impurities in the petroleum can be adsorbed on the replacement strip through the replacement device, thereby reducing the accumulation of impurities on the inner wall of the right-angle elbow, increasing the service life, and reducing the number of maintenance times. However, the existing oil transportation pipelines to prevent wax blockage only provide a solution to the blockage of the right-angle elbow caused by impurities such as paraffin crystals due to the long-term impact of oil. It does not take into account that the inner wall of the transportation pipeline is prone to produce and adhere to a large number of paraffin crystals after the long-term impact of oil, which can easily cause the pipeline to be blocked, which is not conducive to the circulation of oil on the inner wall of the pipeline.
