Color Identification

Colors are intended as a secondary means to identify the contents and characteristic hazards of the piping system. Below are the color guidelines designed to meet or exceed ASME (ANSI) recommendations.

Contents Of The Pipe Color
Fire Quenching Fluids White On Red
Toxic And Corrosive Fluids Black On Orange
Flammable Fluids Black On Yellow
Combustible Fluids White On Brown
Potable, Cooling, Boiler Feed, And Other Water White On Green
Compressed Air White On Blue

Size & Letter Height

The outside diameter of the pipe (including insulation) determines the length of the pipe marker color field and the letter height.

Outside Diameter of Pipe Length of Pipe Marker Color Field Size of Letters
3/4" to 1-1/4" 8 inches 1/2"
1-1/2" to 2" 8 inches 3/4"
2-1/2" to 6" 12 inches 1-1/4"
8" to 10" 24 inches 2-1/2"
Over 10" 32 inches 3-1/2"

Visibility & Location

Visibility and location of the pipe labels are very important. Make sure the pipe markers can be read from a distance.

Installation Recommendations:

  • Above or below center visual line of pipe
  • Frequent intervals on straight pipe runs (visible from any point along the length)
  • Close to valves
  • Near branches and Ts in piping
  • Any change in direction of piping
  • Near points before and after pipe going through walls, ceilings or floors; and at 25' to 50' intervals on long straight pipe runs
