Which section of the ASME code covers fire pressure vessels as referenced here?

• A. Section One
• B. Section Eight
• C. Section Nine
• D. Section Two

Answer: (A)

Fired pressure vessels are boilers, which are heated by combustion. The ASME BPVC groups these under Section I, which sets the design, materials, fabrication, testing, and safety requirements specifically for boilers and other fired pressure vessels. Because the vessel in question is heated by a flame (fired), the rules you’d use come from Section I rather than the sections that cover unfired vessels (Section VIII) or other topics (Section II for materials, Section IX for welding qualifications). So Section I is the appropriate reference for fired pressure vessels.
