Pipe Marking

Pipe MarkingQuickly identify what's in your facility's pipes.

Pipe marking is a critical component of any facility’s labeling. Properly labeled pipes and valves can dramatically reduce the risk of injury or damage should a leak or burst occur, as well as reduce any overall incident response time. ASME/ ANSI A13.1 standards state that employers must label pipes to show contents and color code them to indicate what possible hazards could result from that substance. Pipes containing ammonia, marine vessels, and health care facilities each have their own labeling standards, so be sure to check out our free pipe marking guides for more information.
