Former Inspectors Describe Dangerous Flaws in Construction of Major East Coast Gas Pipeline

In April, a massive explosion ripped through rural Salem Township, Pennsylvania when natural gas from a pipeline buried in a field suddenly ignited.

The Salem Township explosion offers a glimpse at how dangerous a natural gas pipeline accident can be — the blast when the 30-inch pipeline ignited blew a 12-foot deep hole in the ground and scorched 40 acres, sending one man to the hospital with burns on 75 percent of his body.

“It looked like you were looking down into hell,” a local fire chief, Bob Rosatti, told ABC News. “As far across my windshield as I could see was just a massive fireball.”

Is TransCanada Laying Defective Keystone XL Pipe in Texas?

TransCanada, the company currently constructing the southern segment of the Keystone XL pipeline, claims to use “top quality steel and welding techniques” throughout its pipeline network. 

Last week, however, activists fighting the construction of the pipeline released images of what they claim are improperly welded pipeline seams. The photos were released by Keystone XL blockader Ramsey Sprague at the Pipe Tech Americas 2013 conference in Texas and were taken by blockader Isabel Brooks.

Brooks took the photographs from inside a pipe segment on December 3, 2012 to document what they say was daylight pouring through weld seams between segments. “All of us looked at it,” Brooks told DeSmog, speaking of the defective seam, “and it was clear light was coming in from the outside…It was definitely clear what it was.”

An hour after the protesters were extracted from the pipe segment, says Brooks, it was in the ground. “[Other protestors] told me that it was in the ground that day and buried. So they didn't test it again,” she said. “I know exactly the piece of pipe that it's at, so if we were to dig it up I know it would be right there and as clear as that day.”

These two images from inside the pipe were released by Sprague last week:
