Analysis of Mechanical Clamp Plugging Technology for Long Distance Pipeline
Temporary rapid plugging technology should be used for small oil and gas leaks caused by corrosion,cracks,and weld cracking in pipelines.Compared to pipe replacement and B-type sleeve repair technology,mechanical clamp have the advantages of easy installation and no welding risk.Introduced the key performance parameters of domestic bolt fastening clamp and leak plugging clamp.The paper introduces the current status of foreign pipeline mechanical clamp plugging technology,including submarine pipeline plugging technology,pipeline deformation plugging technology,and intelligent plugging technology.Finally,important research directions for pipeline mechanical clamp plugging technology were proposed,including improving the plugging pressure,sealing performance,response speed,and installation timeliness of the equipment.
