Provides more rigorous requirements for materials, design, and nondestructive examination (NDE). It allows for higher design stress intensity values, often resulting in thinner, lighter, and more cost-effective vessels for high-pressure applications.
Purpose
Division 2 is the “premium” option: it allows thinner walls, higher allowable stresses, and more sophisticated analysis (finite‑element, elastic–plastic, etc.) but requires a deeper understanding of the code and more rigorous documentation. asme section 8 div 2 pdf free
