And then there were the dozen others—B31.8S for integrity management, B31G for remaining strength of corroded pipe. Each one a labyrinth of equations, exceptions, and footnotes that could swallow a career. asme pipeline standards compendium
"Flexibility," she said, "is how we got here." The leak was finally capped at 2:17 AM

The compendium at the time allowed a certain margin of acceptable imperfection. The 2004 revision tightened that margin. The 2011 revision added in-line inspection requirements that might have caught the flaw. But the pipeline was built under the 1998 rules. And grandfather clauses had protected it. One dead dog that had wandered into the
