Pressure Vessel Design Review: Impact Test vs. PWHT Cost Considerations
Designing static equipment in accordance with ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 (ASME VIII DIV.1) requires careful consideration of material toughness, especially for vessels operating in low-temperature environments. Impact testing, typically Charpy V-notch, […]
Pressure Vessel Calculations for External Pressure: ASME vs. European Code Approaches
Thin cylindrical shells under external pressure – such as those found in vacuum vessels, underwater pipelines, and jackets – are vulnerable to elastic buckling. The safe design of such shells is addressed by two main regulatory traditions: […]
Pressure Vessel Calculations Review: Nozzle Reinforcement Methods
Introduction Nozzle openings in pressure vessels weaken the pressure boundary, requiring adequate compensation to maintain structural integrity. Examination of nozzles is a critical part in pressure vessel calculations, hence this article examines the main methods for nozzle […]
