Can you use cast iron, ASTM A120 steel, or non-metallic pipe on a Halon 1301 system?

Material compatibility and reliable containment are what this item tests. Halon 1301 systems must use piping that is chemically compatible with the agent and capable of staying leak-tight under the system’s pressure and over long service periods. Cast iron, standard ASTM A120 steel, and non-metallic piping don’t meet those requirements for Halon 1301 service, either due to potential compatibility issues, corrosion, permeation, or inadequate performance under the operating conditions. That’s why none of those options is suitable for Halon 1301 distribution. Only materials listed as compatible by the system designer and applicable codes are permitted.
