Division 2 is categorized as "Engineered Pressure Vessels" due to its sophisticated approach. It utilizes two primary design methodologies: Design-by-Rule (Part 4):
Thus, if you are designing a pressure vessel for high-cycle fatigue (e.g., a compressor pulsation damper) or require the lightest possible weight (e.g., a vessel on an offshore platform), the is your go-to reference. asme bpvc section viii division 2 pdf
No. Division 3 is a separate document within Section VIII. The Div. 2 PDF covers only rules for vessels up to ~3,000 psi (though not strictly limited, its methods work best for moderate to high pressure). Division 2 is categorized as "Engineered Pressure Vessels"
