The oil pipeline (also called pipeline, pipeline) is composed of oil pipe and its accessories, and according to the requirements of technological process, it is equipped with correspondent oil pump unit, and designed and installed into a complete pipeline system for completing the tasks of oil material receiving, unloading and transferring.

The oil pipeline system, i.e. the pipeline system for transporting petroleum and petroleum products, is mainly composed of oil pipeline, oil transportation station and other auxiliary related equipments, is one of the main equipments in petroleum storage and transportation industry, and is also the most main transportation equipment for crude oil and petroleum products.

The pipes of oil pipelines are generally steel pipes, and are connected into long-distance pipelines by welding, flanges and other connecting devices, and valves are used for opening and closing control and flow regulation. The oil pipeline mainly comprises conveying processes such as isothermal conveying, heating conveying, sequential conveying and the like. The corrosion of the pipeline and how to prevent corrosion are one of the important links of pipeline maintenance. Oil pipelines have become one of the major means of transporting oil today and still have considerable potential for development in the future.

The petroleum is viscous and has relatively poor fluidity, and compared with a liquid with high fluidity, the petroleum is relatively slow in conveying speed in the transportation process, and due to interaction of slow flow speed and viscosity, the petroleum is easy to adhere to the inner wall of the pipeline and is condensed in the transportation process, so that certain barrier force is generated on the transportation of the whole petroleum on one hand, the transportation is affected, and on the other hand, the cleaning is difficult, and the petroleum is easy to waste.
