Difference between pipeline plugging and pipeline repair
The function of pipeline repair is to push back the inward collapse of a small area of pipeline to restore the pipeline's circulation ability. At the same time, it can press the inner wall of the pipeline to reinforce the leaking stoppage data; The function of pipeline plugging is to block the pipeline to prevent water from passing through, so as to facilitate construction and other needs.
The diameter of expansion during pipeline repair is limited, that is, it will not expand when it reaches a certain level. At this time, the collapsed part of the pipeline continues to be pressed by the expanding tension and repaired; The expansion force of pipeline plugging is average, so that it can cling to the inner wall of the pipeline to achieve the plugging effect.
