Which code covers the alternative rules for the construction of pressure vessels?

• A. ASME Section VIII div. II
• B. ASME Section VIII div. I
• C. ASME Section VIII div. III
• D. ASME Section VIII div. V

Answer: (A)

The correct choice pertains to ASME Section VIII Division II, which specifically addresses alternative rules for the design and construction of pressure vessels, providing more rigorous requirements compared to Division I.

Division II is aimed at offering a higher level of quality assurance through additional design requirements, materials standards, and inspection criteria. This division is intended for applications where a higher level of safety and reliability is necessary, which could justify the use of alternative approaches in certain situations.

While Division I covers the standard rules for construction, and Division III focuses on pressure vessels for nuclear service, Division V includes non-destructive testing methods. Therefore, these divisions do not apply to the construction rules specified for pressure vessels directly, making Section VIII Division II the appropriate reference for alternative construction rules. Understanding this structure and the specific focus of each division is essential for engineers working with pressure vessels to ensure compliance with safety and design standards.
