Description

A kind of oil pipeline sealing device

technical field

The utility model relates to the technical field of petroleum pipelines, in particular to a sealing device for petroleum pipelines.

Background technique

Oil pipelines are pipelines used to transport oil, and oil pipelines must use certain linking methods to form a complete system. There are three main types of pipeline connections: threaded, welded and flanged. Pipelines with low pressure and small diameter can be connected by screw thread method. This connection method is more convenient. However, since most of the main oil pipelines are generally large in diameter, the other two connection methods are mostly used. Pipes connected by welding have the advantages of convenient construction, firmness, tightness and steel saving. Generally, straight pipes or parts that do not need to be disassembled on curved roads can be used. Where the pipeline needs to be disassembled, flange connection is usually used. In order to ensure the tightness of the flange connection, relatively soft flange gaskets need to be used on both sides of the flange to assist. However, since the environment in which the oil pipeline is located may be harsh, rainwater and dust will cause the seals at the joints to age and fail, resulting in seal failure.
