In order to know what advantages the pipe sealing has, we must first understand what forms of pipe sealing are available
I. the form of pipe sealing:
1) plugging is divided into suspension plugging, barrel plugging, folding closure and capsule plugging by physical and mechanical means
2) the plugging can be divided into stopping, plugging and stopping by plugging according to the flow of the medium in the pipe.
Two, different pipeline plugging technology has different advantages:
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. As a result of tight plugging, toxic and harmful media will not be released into the atmosphere, and environmental protection is high.
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. Because the plugging process is carried out in a completely airtight cavity, completely isolated from the air and without the possibility of fire and explosion, the process has the characteristics of close plugging, high pressure, fast construction and high safety.
3) the above two kinds of pipeline plugging technology usually only need 10-50 minutes, big caliber also only need 6-8 hours, construction period is short, the efficiency is high.
4) the above two kinds of pipeline plugging technology are not stopped production, direct operation can save considerable cost for production and maintenance, especially for gas pipelines, chemical pipelines and oil pipelines. High benefit
