The US has the worlds largest concentration of underground pipelines, consisting of more than 3 million miles of operational energy pipelines. Some of these pipelines were installed in the early 1900s and many have been in service for more than 50 yr. This aging infrastructure presents numerous problems to the operators. This paper reports on one of the most critical of these problems, coating deterioration. Most pipe coating materials deteriorate with time as the result of moisture absorption, soil stress, rock abrasions, tree roots, bacteriological attacks and numerous other causes. Eventually the coating deteriorates to a degree that requires corrective measures to maintain compliance with US Department of Transportation regulations governing operation of natural gas and hazardous liquids pipelines. Recent statistics released by the DOT indicate that more than 50,000 miles of existing US pipelines will require rehabilitation or other corrective measures within the next 10 yr, with more than 6,000 miles needing rehabilitation within the next 3 yr.
