Additional boiler and refrigeration codes

There are other boiler, pressure vessel, and refrigeration codes that apply to specific industries and equipment regulated under PEBPVRSR.

We would like to update the PEBPVRSR to align with using the following codes:

ANSI CGA G-2.1-2023 Requirements for the storage and handling of anhydrous ammonia
NFPA 85 Boiler and combustion systems hazards code (2019)

Note: The 2014 edition of ASME PTC 25 Pressure Relief Devices will remain in use in the PEBPVRSR.

ANSI CGA G-2.1-2023 Requirements for the storage and handling of anhydrous ammonia

American National Standards Institute (ANSI) publishes codes for various types of technical equipment. ANSI CGA G-2.1 applies to ammonia stored in pressure vessels as a gas, mostly used in agricultural settings as a fertilizer. It does not apply to ammonia manufacturing plants, or refrigeration systems that use ammonia as a refrigerant.

NFPA 85 Boiler and combustion systems hazards code (2023)

National Fire Protection Association (NFPA) publishes codes to prevent fires and explosions in technical equipment. NFPA 85 Boiler and combustion systems hazards code covers the design, installation, operation, maintenance and training associated with combustion systems for boilers, pulverized fuel systems, and steam generators.

To be removed: Standards of the Tubular Exchanger Manufacturers Association (TEMA)

The Tubular Exchanger Manufacturers Association publishes standards for designing and manufacturing heat exchangers. ASME is the primary code for the construction of pressure vessels and the TEMA standards act as a secondary design code. We plan to remove the direct reference to the TEMA standards in the PEBPVRSR, to clarify their intended use as a secondary design code.
