Text Sizing: ASME (ANSI) Size Recommendations The legend (name of pipe content) and directional flow arrow is the primary means of identifying pipe content. A13.1-2007 standard makes recommendations as to the size of letter height and length of color field for various pipe diameters. Pipe Marking 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." Color Standards: ASME (ANSI) Color Recommendations Unmarked pipes mean danger - to both life and property. Numerous injuries have occurred through ignorance of pipe contents, particularly when outside agencies are called in under emergency conditions.
