Which code addresses refrigeration piping?

• A. Section I
• B. Section VIII Division 2
• C. Section VIII Division 1
• D. B31.5

Answer: (D)

Refrigeration piping is addressed by the ASME code that is specifically dedicated to that service: B31.5, Refrigeration Piping and Heat Transfer Components. This code sets the requirements for piping systems that carry refrigerants, covering design, materials, fabrication, testing, and safety for refrigerant loops and associated components. The other options belong to different areas of the ASME Code: Section I covers boilers, and Sections VIII Division 1 and Division 2 cover pressure vessels. While process piping is governed by B31.3 in many applications, refrigeration piping has its own specialized code, B31.5, because refrigerants present unique safety and thermal considerations.
