California PUC orders PG&E to reduce gas pressurePosted: December 22, 2010 at 12:21 am by Roz Potter in Infrastructure Failure, Personal safety
The NTSB, the agency charged with investigating the San Bruno gas pipeline explosion has found that the failed pipe was not welded properly. In addition, discrepancies were discovered between PB&E records and the type and condition of pipe found. The failed pipe segment should have been welded from both inside and outside. Instead, only outside welds were found in some portions.
As a result of the findings, the California Public Utilities Commission has ordered PG&E to reduce the pressure of gas in its lines.
