Description

technical field

[0001] The invention relates to a pipeline maintenance and repair equipment technology, which is used for the sealing of the pipeline, blocking the sealing from the pipeline, so as to carry out various maintenance and repair projects. It is suitable for all kinds of pipelines, especially for the sealing of underground, underwater and submarine oil and gas pipelines. Background technique

[0002] With the rapid development of the economy, various pipelines, especially underground, underwater, and seabed drainage, oil, and gas pipelines are constantly being built in large numbers. During the construction and operation of the pipeline, the maintenance, failure and repair of the pipeline are inevitable. The maintenance and repair of the pipeline often need to block the pipeline in the faulty section first, so as to set up the necessary maintenance and repair site. And due to the complexity of the environment, the pipeline plugging operation required for this pi...
