In-line inspection of natural gas pipelines. Topical report, May 1993

Technical Report · Sat May 01 00:00:00 EDT 1993

OSTI ID:5960276

The topical report describes the family of in-line, self-contained devices, called 'pigs,' that may be employed as tools in an overall integrity assurance program. Pigs are used in a variety of applications ranging from simple cleaning to sophisticated nondestructive evaluation (NDE) of pipelines. Utility pigs perform strictly mechanical functions such as cleaning; instrumented pigs carry sensors, electronic circuitry, and often onboard data recording capabilities for use in in-line inspection (ILI). Pipeline conditions such as valves, restrictions, and bends, as well as access to the pipe must be evaluated to determine the feasibility of a pigging operation. ILI data can provide information on pipeline anomalies that may affect the integrity of the pipeline.
