A 6 year field study by TransCanada PipeLines Ltd. (TCPL) of stress corrosion cracking (SCC) on its natural gas pipeline system has yielded important information about the origins and occurrance of SCC. This paper reports that the study was prompted by three 1986 in-service line failures attributable to SCC. Whether during service or TCPL's subsequent testing, SCC failures have occurred only in Class 1 locations (little or no human population). More populated areas on TCPL's system are protected by use of heavier wall pipe which consequently has greater flaw tolerance. SCC, which in some cases led to both in-service or test ruptures, was detected under both polyethylene tape coated and asphalt-coated pipeline section.
