Survey.The most only revealing relatively greatly or can find after accident generation, the repairing of accident is the most simply mended the fold after the sheep is lost.Summer manages
During net maintenance is investigated, needing system carries out boosting detection leak source, testing cost is high, and interior media leaks meeting after boosting
It is further exacerbated by heat-insulation layer humidity scope, causes further heat-insulation layer outward leakage fault spread, cause greater area of pipe
Road corrodes.From above-mentioned, traditional leak detection method is both unfavorable for checking erroneous ideas at the outset, and finds accident potential, is unfavorable for again saving energy
Source.
