Pipeline Failure Results from Lightning Strike: Act of Mother Nature?
- 299 Downloads
There are more than 2.5 million miles of oil and gas pipelines in the United States. Approximately 900 failures occurred on hazardous liquid pipelines from 2002 to 2003, and 9% of these failures were attributed to damages due to natural force, which included lightning strikes, among other naturally occurring events. This paper provides a case history in which failure analysis was applied to determine the metallurgical cause of a failure involving a polyethylene-coated hydrocarbon pipeline that leaked as a result of a lightning strike.
