Check Nozzle Loads With WRC 537/WRC 107

Check Piping Loads on Nozzles Using WRC 537 Process piping imposes external loads on vessel and exchanger nozzles that must be accounted for (see ASME VIII-1, UG-22).  Stresses on pressure vessel nozzles and attachments have historically been checked using the Welding Research Council Bulletin 107.  WRC 537 was published in 2010 and was meant [...]

Multiple Chamber Pressure Vessel Design

Certain industrial processes require pressure vessels to be built with multiple chambers operating under different design conditions.  COMPRESS and INSPECT both support multiple chamber pressure vessel designs.  Benefits of using this feature include: An accurate weight calculation. Assurance that changes made to the chambers are accounted for in the overall [...]

Why Perform UG-99 Hydrostatic Test 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 [...]

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 [...]
