Abstract

The invention belongs to the field of oil production equipment in oil fields, and in particular relates to an anti-corrosion oil pipeline. Including the oil pipe body, the upper and lower ends of the oil pipe body are respectively provided with an upper joint and a lower joint. The inner side of the upper joint and the outer side of the lower joint are processed with matching standard oil pipe sealing taper threads. The inner liner layer is made of high-quality material, and the inner liner layer extends upwards to the lowermost end of the inner thread of the upper joint, and extends downwards to the lower end surface of the oil pipe body. In the present invention, a stainless steel lining layer is provided on the inner side of the oil pipe, which can effectively improve the anti-corrosion performance of the inner wall of the oil pipe. In addition, the present invention also sets an electric heating layer in the wall of the oil pipe. Scale, reduce the corrosion of the oil pipe by the chemical components in the scale, so as to further improve the anti-corrosion performance of the oil pipe.

Description

technical field [0001] The invention belongs to the field of oil production equipment in oil fields, and in particular relates to an anti-corrosion oil pipeline. Background technique [0002] Oil pipelines are commonly used infrastructure in oilfield production, but in actual use, under the action of complex physical and chemical environments, the inner wall of the oil pipeline is easily corroded, which affects the service life of the oil pipeline. Therefore, it is necessary to design a better oil pipe with anti-corrosion performance to solve the above problems. Contents of the invention [0003] The present invention provides an anti-corrosion oil delivery pipeline to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present invention adopts following technical scheme to realize: [0005] An anti-corrosion oil delivery pipeline, comprising a pipeline body, the upper and lower ends of the pipeline body ar...
