Characteristics of different pipeline plugging techniques
1. barrel plugging. Pipe type plugging is suitable for pipelines, scaling and corrosion on the inner wall of pipelines, as well as deformed pipes. They are generally used in the production lines of oil fields and petrochemical systems. The process has tight plugging and is free from the limitation of pipeline age.
2. disc plugging. Pipeline disk sealing is suitable for long distance pipelines with no scaling and corrosion on the inner wall of pipelines. Most of them are used for long-distance transportation pipelines of petroleum, natural gas and finished oil, as well as pipeline repair work. The process is characterized by tight plugging, high pressure and fast construction. Pipe opening with pressure
