Check Piping Loads Using WRC 107, 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 [...]
Having trouble viewing this video? Download video (.mov 10MB) Stacked Vessel Design Using COMPRESS Certain industrial processes require pressure vessels to be built with multiple chambers operating under different design conditions. COMPRESS and INSPECT both support multiple pressure chamber, stacked vessel designs. Benefits of using this feature include: Individual pressures, temperatures, [...]
The Codeware HTRI interface COMPRESS and INSPECT offer a bi-directional interface with HTRI’s Xchanger Suite Xist®. This feature saves time and enhances collaboration between Mechanical and Thermal Designers. The HTRI interface is included at no additional charge with INSPECT and is provided with the COMPRESS Heat Exchanger Option. Xchanger Suite Xist users can [...]
Support Skirt Openings Piping connections to vertical vessels often require additional piping and an opening cut out of the support skirt. COMPRESS includes the ability to specify and check the adequacy of this commonly encountered design detail. Circular pipe sleeves, internal projections, tilt angles, and skirt reinforcing pads can be considered. The ability [...]

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, [...]
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 [...]
