Canadian workplaces may follow ANSI A13.1 and IIAR ammonia pipe marking standards as a guideline for a holistic pipe marking system. Established in 1987, the Ammonia Safety & Training Institute (ASTI) is a 501(c)(3) organization dedicated to making ammonia (NH3) the safest managed hazardous material in the world. The base rules for piping engineering are the ASME B31 Codes (herein referred to as the Codes). The basis for the development of the guidelines was ANSI Standard A13.1–1981 “Scheme for Identification of Piping Systems.” ANSI A13.1 was revised in 2007. It also includes hangers and supports, and other equipment items necessary to prevent overstressing the pressure containing parts. Multi-color, large format, DuraLabel Toro IIAR (International Institute for Ammonia Refrigeration) Pipe Color Code Chart: The IIAR pipe marking system applies to ammonia pipes used in ammonia refrigeration systems. The colors may be applied using paint over the length of the pipe or as bands of color. It also does not apply to water piping; piping designed for external or internal gage pressure not exceeding 15 … Pipe color-coding is not a complicated process, especially if industry standards are used. Design of chemical and petroleum plants and refineries processing chemicals and hydrocarbons, water and steam. Ammonia Refrigeration eTool. ANSI A13.1 Pipe Color Code Chart: ANSI A13.1 pipe marking code is the standard most often used for pipe marking. Blog. This Code also covers safety aspects of the operation and maintenance of those facilities. If you use ammonia refrigeration piping and system components, it’s crucial that you understand the most recent pipe labeling requirement changes made by the IIAR (International Institute of Ammonia Refrigeration). .. For ammonia systems, IIAR Bulletin also addresses the subject of safety valves. Pipe material 20" ; … active, Most Current.
