NFPA 2001 2018 is the standard that provides the minimum pipe design pressure for HFC-227ea when the container pressure is 249 psi.

NFPA 2001 2018 is the standard that provides the minimum pipe design pressure for HFC-227ea when the container pressure is 249 psi.

• A. NFPA 12 2018
• B. NFPA 12A 2018
• C. NFPA 2001 2018
• D. NFPA 17A 2017

Answer: (C)

In clean agent systems using HFC-227ea, the piping must be designed to withstand the system’s maximum pressure, which comes from the container precharge. NFPA 2001, 2018 edition, is the standard that governs these clean‑agent systems and specifies the minimum pipe design pressure to handle the container pressure. With a container pressure of 249 psi, NFPA 2001 2018 dictates that the piping be designed to meet or exceed that pressure. The other standards pertain to different types of extinguishing methods or agents and do not provide the pipe design pressure requirements for HFC-227ea.
