[0002] The oil pipeline (also called pipeline, pipeline) is composed of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow, designed and installed into a complete pipeline system to complete the oil loading and unloading and transfer tasks. 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. It is one of the main equipment in the oil storage and transportation industry, and it is also the most important transportation equipment for crude oil and petroleum products. Compared with railway and road 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. The pipes of oil pipelines are generally steel pipes, which are connected into long-distance pipelines using welding and flange connection devices, and valves are used for opening and closing control and flow regulation. The main transportation processes of oil pipelines are isothermal transportation, heating transportation and sequential transportation. Pipeline corrosion and how to prevent corrosion are one of the important links in pipeline maintenance. Oil pipelines have become one of the main means of transportation for oil, and still have considerable development potential in the future.

[0012] Technical effects and advantages of the present invention: 1. A second diverter ring is arranged inside the first diverter ring. When the diverted oil passes through the first diverter ring, it is diverted again through the second diverter ring inside the first diverter ring, thereby reducing the pressure generated by the oil contacting the first diverter ring. A first connecting ring is arranged on the inner wall of the second diverter ring. A second connecting ring is arranged inside the first connecting ring to connect with the first connecting ring, so that the connecting arm on the inner wall of the part connecting ring fixes the second connecting ring. When the flow speed of the oil in the oil pipe is too high, a large amount of oil flows first through the cavities inside the first diverter ring and the second diverter ring. When the oil flows, the through grooves inside the first diverter ring and the second diverter ring are staggered, so that when the oil flows rapidly, the second diverter ring rotates within a rotation range inside the first diverter ring, thereby forming a layered turbulence phenomenon and reducing the flow pressure of the liquid inside the oil pipe. 2.

In order to avoid the oil pipe as a whole being damaged due to the pressure of the oil flow, a first diverter ring is provided inside the oil pipe to divert and process the oil flowing inside the oil pipe, and a reinforcement ring is provided on the inner wall of the first diverter ring so that the reinforcement ring reinforces the multiple groups of first diverter rings to prevent the first diverter rings from being deformed as a whole due to the influence of resistance when the first diverter rings divert the flowing oil, causing the first diverter rings to be blocked inside the oil pipe; 3. A first explosion-proof ring and a second explosion-proof ring are arranged inside the oil pipe to reinforce the internal parts of the oil pipe, and a first steel wire protection ring is arranged inside the first explosion-proof ring and the second explosion-proof ring to reinforce the oil pipe as a whole. The first contact strip on the surface of the first steel wire protection ring contacts the second explosion-proof ring as a whole, so that the second explosion-proof ring as a whole increases the pressure resistance, and a second steel wire protection ring is arranged between the oil pipe and the second explosion-proof ring. When the pressure inside the oil pipe is too high, the pressure is evenly dispersed to the oil pipe as a whole through the second contact strip on the surface of the second steel wire protection ring, so that the pressure inside the oil pipe is dispersed, and reinforcement ribs are arranged inside the oil pipe. The reinforcement ribs are wrapped around the inside of the oil pipe as a whole, so that the overall strength of the oil pipe is increased. BRIEF DESCRIPTION OF THE DRAWINGS
