Tangential, Tilted and Hillside Nozzle Design

Due to process and pipe routing considerations, nozzles on pressure vessels and heat exchangers are frequently placed in non-radial orientations. These non-radial or hillside nozzle to vessel intersections create obround openings which require additional geometric calculations to meet ASME VIII BPVC rules. Put another way, the nozzle opening diameter d used for UG-37 reinforcement [...]

Pressure Vessel Component Design With COMPRESS

Simple Pressure Vessel Component Design COMPRESS does not require you to model an entire pressure vessel to design or rate individual components. This capability is useful when investigating a pressure vessel component that must be modified. For complicated components, like Appendix 2 flanges and nozzles, the user can call upon a specific [...]

Why Perform UG-99 Hydrotest Stress Calculations?

ASME UG-99 Hydrostatic Test Stress Calculations ASME Code paragraph UG-99 requires that all vessels undergo hydrostatic (or pneumatic) testing before Code stamping. As this test provides mechanical stress relief it may be thought of as the final step in the fabrication process. The UG-99 hydrostatic test is an effective way to screen for design, [...]

Why Specify Pressure Vessel Weld Seams?

The Advantages of Locating Pressure Vessel Weld Seams Although not required to perform basic (theoretical) ASME calculations, specifying weld seam locations when designing pressure vessels provides a number of practical advantages: Tall towers often require greater thicknesses near the bottom to resist wind and seismic loadings. Locating circumferential shell seams is [...]
