Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure oil pipes, and particularly relates to a high-pressure oil pipe resistant to aging. Background Art

[0002] An oil pipe is a pipeline that transports crude oil and natural gas from an oil and gas layer to the surface after drilling is completed. It is used to withstand the pressure generated during the exploitation process. It can be divided into two types: high-pressure and low-pressure. A high-pressure oil pipe is a component of a high-pressure oil circuit. It is required that the oil pipe can withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. Vehicle high-pressure oil pipes mainly appear in high-pressure injection diesel engines and high-pressure injection direct-injection gasoline engines, and can withstand the oil pressure required during the operation of the engine.

[0003] For example, the Chinese patent with the publication number CN214947048U discloses an anti-aging rubber oil pipe for automobiles, which includes a circular pipe body. The pipe body includes a base layer on the innermost layer, and the material of the base layer is nitrile rubber, which has good low-temperature resistance. An anti-seepage layer made of butyl rubber is arranged on the surface of the base layer. A woven layer woven from mixed textile polyamide fibers is arranged on the surface of the anti-seepage layer. An asbestos layer for heat protection is arranged on the surface of the woven layer. An antioxidant layer made of fluororubber is arranged on the surface of the asbestos layer.

[0004] The above patent has the following problems:

[0005] Compared with the prior art, the materials of the oil pipe body are not enough, and the oil pipe body cannot be protected. After long-term use, the oil pipe will be eroded by liquids, affecting the normal use of the oil pipe, reducing the working efficiency of the oil pipe. Moreover, the sealing performance of the oil pipe in the prior art is not good enough. When the oil pipe is working, oil may leak, soiling the oil pipe and wasting oil, increasing the production cost of oil and delaying the oil transportation work. In view of this, we propose a high-pressure oil pipe resistant to aging. Summary of the Utility Model
