ASME (ANSI) Standard A13.1-2007

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."


Brady Pipe Marking Systems Meet the ASME (ANSI) Standard

The Brady Pipe Marking System instantly tells you all you need to know: pipe contents, direction of flow, whether hazardous or safe.

ANSI Size Recommendations

The A13.1-2007 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.

ANSI Color Recommendations

Unmarked pipes mean danger - to both lifeand property. Numerous injuries have occurred through ignorance of pipe contents, particularly when outside agencies are called in under emergency conditions.

ANSI Visibility Recommendations

"Markers shall be located so that they are readily visible to plant personnel from the point of normal approach." Brady Pipe Markers instantly tell you all you need to know about pipe contents, direction of flow and whether hazardous or safe.
NOTE: For pipes less than 3/4" in diameter, a permanently legible tag is recommended.
