Research on the Design Criterion of Packers and Slips in Pipeline Isolation Tool

With the rapid development of pipeline industry, the pipeline maintenance technology using isolation tool has got developed widely in the global scope. The packers and slips are the determining parts for isolation reliability and their design criterions are essential to investigate. This paper firstly studied the contact pressure between the packers and pipeline through theoretical and simulation methods. And then the modified model has been achieved according to the analysis results. Finally, the design criterions of packers and slips have been presented accordingly. The results of this research has great meaning and provide efficiency and convenience for tool designing in engineering.
