ASME Standards for Pipe Marking

ASME (ANSI) Standard A13.1-1996

The ASME (ANSI) Standard for pipe identification is a widely used guideline in determining pipe identification requirements. The purpose of the standard is to "assist in identification of hazardous materials conveyed in piping systems and their hazards when released into the environment." "Pipes are defined as conduits for the transport of gases, liquids, semi-liquids or fine particulate dust." In Canada, the ASME standard is commonly followed. Where WHMIS controlled substances are contained in piping systems, the appropriate WHMIS symbol(s) must be included in the pipe marker legend.

We carry Pipe Marking Systems that meet the ASME (ANSI) A13.1-1996 Standard and size recommendations.

The A13.1-1996 standard also makes recommendations as to the size of letter height and length of color field for various pipe diameters. These recommendations are shown in the table below.

Outside Diameterof Pipe/Covering Length of Color Field Size of Letters
3/4" to 1 1/4" 8" 1/2"
1 1/2" to 2" 8" 3/4"
2 1/2" to 6" 12" 1 1/4"
8" to 10" 24" 2 1/2"
Over 10" 32" 3 1/2"

Note: For pipe less than 3/4' in diameter, a permanently legible tag is recommended.
