Pipe color code charts are available from companies such as Graphic Products, Grainger and Labeltac. All of these companies offer color code charts on their websites, and some let users order free printed charts for offline use.
Graphic Products offers the ANSI A13.1 pipe marking code, which is the standard used in the industry, as well as a commercial building color code chart and the IIAR pipe marking system. Grainger also provides the ANSI A13.1 color code and offers detailed information about label requirements and placement. Labeltac allows consumers to order a free guide for marine and offshore pipe marking standards.
