Dear Mr. Carlisle:
This is in reply to your letter dated February 8, 1977, regarding pipeline maintenance procedures for liquid pipelines.
QUESTION: "When it becomes necessary to replace a short damaged section of pipe during pipeline maintenance using a butt weld joining technique, does DOT recognize visual
inspection of the weld as a 'safe manner' procedure."
ANSWER: Whenever a segment of an existing pipeline is replaced, relocated, or otherwise changed, the new portion, in addition to being subject to the reporting, operating,
and maintenance requirements, is also subject to the design, construction, and testing requirements of Part 195. Visual inspection of a weld is a safe manner procedure and is an acceptable inspection method.
However, as specified in Section 195.228(a), ". . . Visual inspection must be supplemented by nondestructive testing." The criteria for nondestructive weld testing is specified in Section 195.234, Welds: Nondestructive testing and retention of testing records.
Thank you for your interest in pipeline safety.
Sincerely,
Cesar DeLeon
Acting Director
Office of Pipeline
Safety Operations
