There are many types of oil and gas storage and transportation pipelines, and the classification methods are different. According to the type of the transported medium, oil and gas pipelines can be divided into crude oil pipelines, refined oil pipelines, natural gas pipelines, oil and gas mixed pipelines, etc. According to the location of the pipeline, oil and gas pipelines can be divided into land pipelines and submarine pipelines, etc.

[0003] In the prior art, a patent document with publication number CN220435714U proposes an oil and gas storage and transportation pipeline, including a first pipeline and a second pipeline, the first pipeline and the second pipeline are respectively fixedly connected with a first flange and a second flange at both ends, a sealing mechanism is arranged between the first flange and the second flange on the opposite side, the sealing mechanism includes a trapezoidal sealing ring, a sealing groove matched with the trapezoidal sealing ring is provided on one side of the first flange, and an annular groove is provided on one side of the second flange. The utility model relates to the technical field of oil and gas pipelines. The oil and gas storage and transportation pipeline seals the connection between the first pipeline and the second pipeline through the trapezoidal sealing ring to prevent pipeline leakage. During use, when the elasticity is weakened, the trapezoidal sealing ring can be squeezed to continuously move into the sealing groove under the elastic force of the arc-shaped spring sheet and the spring to make up for the lost elasticity, so that the sealing of the pipeline connection is better and the service life of the sealing ring is extended.

[0004] In order to solve the problem that the rubber sealing ring at the connection between the pipelines is used to seal the two connected pipelines, but the sealing ring is affected by the external storage and transportation environment and the storage and transportation oil and gas temperature during long-term use, which will accelerate its aging problem.
