Pipeline rupture incident report released; Rupture caused by pipe corrosion

A stress corrosion crack caused the massive natural gas explosion March 3 north of Mexico, according to an incident report.

The report, filed by Energy Transfer Partners with the Pipeline and Hazardous Materials Safety Administration, was released April 2. Energy Transfer is the owner of the Panhandle Eastern Pipeline, which ruptured approximately one mile north of Mexico near Missouri Highway 15. The company had 30 days to submit a report to the safety administration.

The 30-inch diameter pipe is comprised of carbon steel, with a specified minimum yield strength of 60,000 pounds per square inch. Pressure inside the pipe did not exceed the maximum allowable operating pressure. The investigation did not find evidence of human error or control room malfunctions.

The widest part of the rupture was 94 inches and the entire rupture’s circumference was 864 inches in a pipe buried five feet underground. Two people were evacuated from the incident area, but no injuries or fatalities were reported.

1. Thanks for the article and link...very informative ...

Pipelines run all over MO. Down in Bennett Springs MO, we had constant mailings about the pipeline running through that area (down double OO highway on the way to highway 32 from BSMO there is a pipeline running N-S axis). Fortunately we've had nothing happen, other than a notice of some enhancement or something like that to occur with the line.

2. My pleasure

They indeed do run everywhere and have for many, many years. My Great Uncle worked as an aircraft mechanic at Lambert Field in the 1930s on the Shell Oil Company Plane that was fitted with a camera to take photos of their pipelines. I have a photo of him on the tarmac by the Old Terminal Building that was on Lindbergh Blvd.

4. Unfortunately he was gone before I arrived

On the planet so I got a few bits and pieces. Hope that you made it through the storm okay.

much, I'll get John Beal out here to look at hopefully tomorrow. Doesn't look like a lot of damage (or at least, I hope not). Take care. Nt
