Almost Zero Leakage
Roger Beiler · 2001
Leakage testing of pipelines frequently is performed at the pipe manufacturing facility and again after the pipeline has been installed and backfilled. This paper discusses the formulas in various standards used to compute allowable leakage in pressure pipelines, the techniques commonly used for leakage testing, and problems that can be encountered. Pipe materials discussed in the paper include low-head concrete pipe, high-head concrete pipe, steel pipe with rubber-gasket joints, steel pipe with welded joints, ductile iron pipe, polyvinyl chloride (PVC) pipe, and high-density polyethylene (HDPE) pipe.
