Unwanted Night Moves

Whenever the subject of internal corrosion in pipelines comes up, it rekindles some unpleasant memories from my extensive time as a pipeline company spokesperson. Being part of an emergency response team for over 12 years was rewarding in many ways, but there was always an uneasy feeling when the phone would ring in the middle of the night.

Damage Tolerance Testing of Small-Diameter Pipelines

Internal and external corrosion, as well as third-party damage such as dents and gouges, are the main causes of pipeline failures worldwide. When such damage is detected by direct inspection, or in-line inspection methods, a decision to replace, repair, or accept and monitor must be made.

San Francisco Gas Explosion Shoots Fire that Burns Buildings

A gas explosion in a San Francisco neighborhood shot flames into the air for hours Wednesday and burned five buildings, sending panicked residents and workers fleeing into the streets. It took utility crews more than two hours to put out the fire after private construction workers cut a natural gas line, igniting the towering flames.
