A Pennsylvania gas utility says defective pipes were used at thousands of buildings in Virginia, Pennsylvania and surrounding states but there is no immediate cause for concern.
A company spokesman says Columbia Gas of Pennsylvania and its sister companies in Ohio, Maryland, Kentucky and Virginia installed the pipes at about 28,000 buildings before a worker noticed the problem in June.
Columbia spokesman Mike Marcus tells "The Pittsburgh Tribune-Review" the walls of the pipes are too thin. A Canadian company has been retained to test the pipes, which were produced by Gainesville, Texas-based Polypipe.
Officials from Columbia and Polypipe say the thin walls don't make the pipes more vulnerable to failure but could shorten their life span. The pipes will stay in place until tests are completed.
Polypipe officials blamed malfunctioning cooling equipment for the thin walls.
