Which ASME code covers piping attached to a power boiler?

• A. B31.1
• B. B31.3
• C. B31.5
• D. B31.8

Answer: (A)

Piping around power boilers is governed by the Power Piping code. ASME B31.1 covers the design, materials, fabrication, assembly, examination, testing, and safety of piping systems in electric power generating stations and related facilities, including boiler piping, steam lines, condensate, and feedwater lines. This distinguishes it from other codes: B31.3 is for Process Piping in chemical and related industries, B31.5 covers Cryogenic Piping, and B31.8 addresses Gas Transmission and Distribution. So the piping attached to a power boiler falls under ASME B31.1.
