Using Pipe Markers To Improve

What is a pipe marker?

It is simply a label applies to a pipe that identifies the contents, type of hazard and the direction of flow of the contents of the pipe. The label color shows the type of hazard. Arrows indicate the direction of flow. An text printed on the label identifies the contents of the pipe.

There are codes that set the standards used for pipe markers. Standard colors must be use. There is a minimum size for the label, and the text on the label, based on the diameter of the pipe. The code that most often applies is the ANSI A13.1 pipe marking code. Other codes cover specialized applications such as ammonia refrigeration pipes, medical gas pipes, and pipes on ships.

Pipe markers are not only required by code, they improve productivity by providing needed information at the point of need. For example, knowing the direction of flow can be critical for knowing which valve to close to shut off that flow. And knowing the contents of each pipe helps ensure the correct valve is closed.
