ASME B31.5 applies to which piping system?

• A. Refrigeration piping
• B. Nuclear piping
• C. Chemical process piping
• D. Hydraulic piping

Answer: (A)

ASME B31.5 is the standard that governs refrigeration piping and heat transfer components. It applies to piping systems that carry refrigerants and the associated equipment such as condensers, evaporators, and other heat exchangers in refrigeration installations. The code covers design, materials, fabrication, inspection, testing, and safety requirements to ensure leak-tight and safe operation under the system’s designated conditions.

Other options relate to different ASME areas: nuclear piping is typically governed by the nuclear portion of the Boiler and Pressure Vessel Code (and related nuclear standards), chemical process piping is addressed by ASME B31.3, and hydraulic piping falls outside the scope of B31.5.
