ANSI/ASME A13.1 is the pipe marking standard that informs facilities how to label their pipes using specific guidelines. These include designated colors, sizes, directional arrows, and size and style of text.
Knowing a pipe's contents and flow direction can have a substantial impact in an emergency situation. Having a uniform pipe marking system in your facility makes it easier for employees, maintenance workers, and emergency responders to act in a way that minimizes loss and improves outcomes.
