After Blasts, Massachusetts Gas Customers Face Long Wait

The rogue natural gas pressure surge that led to dozens of home explosions last week in Massachusetts very likely damaged the system’s antiquated network of pipes and could require lengthy testing and repair before service is restored to thousands of customers. An apparent malfunction sent gas through the pipelines at 12 times the normal pressure before the blasts last Thursday, perhaps more in places, according to data released by lawmakers and investigators. Much of the system is made of cast iron, which is brittle and can crack under pressure, said Richard Kuprewicz, a consultant who specializes in pipelines.
