TRANSCONTINENTAL GAS PIPE LINE CORPORATION, 30 INCH TRANSMISSION LINE FAILURE NEAR BEALETON, VA

The report describes and analyzes a pipeline failure and resulting fire in a rural area near Bealeton, Va. Although no one was killed or injured, the accident would have been castastrophic if it had occurred in a more densely populated area. The National Transportation Safety Board determines that the probable cause of the accident was the failure of the 30-inch pipe because of a hydrogen stress crack propagation at a hardspot in the pipe wall. The hardspot probably had been created during pipe manufacture.
