External Flange Loads and ASME UG-44 Do you need a way to combine pressure and external loads when designing pressure vessel flanges? With the release of the 2019 Edition of the ASME Code, Code Case 2901 has been moved into UG-44, a mandatory Code paragraph. Applying this recent Code change in COMPRESS helps [...]
COMPRESS 7710 New Features Include: Copy and Paste Nozzles Nozzles can now be copied and pasted between any components currently displayed in the 3D view, including between components on different vessels. To access this time saving new COMPRESS 7710 feature, select a nozzle from the Component Tree, activate the Copy Selected button, [...]
Standard ASME B16.5/16.47 flanges usually provide the most cost effective solution for bolted connections. For cases where no standard flange exists, the more complex rules of ASME Appendix 2 can be used. The COMPRESS Flange Wizard is a tool that creates optimized Appendix 2 flange designs with minimal time and effort. [...]
Do you need to quote a vessel or exchanger for a rush job? COMPRESS includes a wizard interface which requires only basic information to model complete pressure vessels (shown above) and Heat Exchangers. The vessel and exchanger wizards call upon component wizards to create an optimum design. Good engineering practices are built [...]
Would you like to save paper when printing your reports? With COMPRESS and INSPECT you can customize your reports to suit your needs. Having trouble viewing this video? Download video (.wmv 13MB)
The COMPRESS user interface and basic program operations are covered in this short training video. COMPRESS boosts engineering productivity by handling the complex rules of the ASME Code. It performs comprehensive engineering calculations and allows you to quickly produce customized pressure vessel and heat exchanger design reports. COMPRESS saves time and helps [...]
ASME VIII-1 Appendix 46 Using Division 2 Rules With Division 1 Allowable Stresses COMPRESS implements ASME Appendix 46 calculations as a standard feature. In ASME Code Editions before 2019 these provisions were covered by Code Case 2695 (CC 2695). Selecting this option directs COMPRESS to use ASME VIII-2, Part 4 (Division 2) [...]
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 [...]
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 [...]
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 [...]
