Which section of the ASME code governs the design of pressure vessels?

• A. ASME Section VIII
• B. ASME Section IX
• C. ASME Section I
• D. ASME Section II

Answer: (A)

Design rules for pressure vessels come from the ASME Boiler and Pressure Vessel Code, and the section that covers the design is Section VIII. This part lays out how to size shells and heads, determine wall thickness, select materials, and plan nozzle reinforcements while considering internal pressure, temperature, and corrosion. It has two divisions—Division 1 for standard design requirements and Division 2 for more stringent rules when higher design margins are needed. Other sections serve different purposes: Section IX handles welding and brazing qualifications, Section I applies to power boilers, and Section II lists material properties used in codes. So for the design of pressure vessels, Section VIII is the appropriate chapter.
