Pipe sealing is a rigorous engineering task which requires high accuracy and careful work.
1, plugging according to physical and mechanical means are divided into suspension plugging, barrel plugging, folding sealing, bladder plugging and other forms.
2 、 the sealing is divided into stopping, plugging and stopping by plugging according to the flow of the medium in the pipe.
The main characteristics of the pipeline are constant pressure transmission, opening, sealing and modification. The process is advanced, the operation is continuous, safe and reliable, no flame operation, wide range of use and no pollution.
Pipe sealing technology -- tube plugging, pipe type plugging, suitable for pipeline internal wall scaling, corrosion pipeline and irregular deformation pipeline, generally used in oil field and petrochemical system production pipeline. The process has tight plugging and is free from the limitation of pipeline age.
Pipeline plugging technology, disc plugging, pipeline pipe plugging disc suitable for pipeline and the inner wall of the pipeline without fouling, corrosion, mostly for pipeline transport oil, natural gas, oil, and pipeline repair work, the process has the characteristics of high pressure bearing, Feng Duyan density, fast construction.
