Two pipe labeling guides are available:

The standard pipe labeling guide, shown to the right, gives the basics of industrial pipe identification as defined in the pipe labeling requirements of both the ANSI A13.1 and ASME A13.1 codes. These are the pipe labeling standards used by most facilities. This guide shows you, at a glance, the color code, label and text size, and recommended label locations for pipe markers. Using this standardized system allows quick identification of pipe contents and their associated hazard potential.

The second pipe labeling guide (shown to the left) is a specialized guide to labeling ammonia refrigeration pipes. It gives the International Institute of Ammonia Refrigeration's (IIAR) pipe identification standards.
