Carbon Steel Materials and Unexpected Brittle Fracture It’s been a while since I posted anything so I thought I would touch on an issue that recently came to my attention. Today’s blog entry deals with certain carbon steel materials and unexpected brittle fracture. We all know all materials are not created exactly the same. There [...]
Clients often ask us “why should my company adopt solid modeling?” and “what are the advantages over my current method?”. In this article I hope to shed some light on these questions and also provide my overall impression of where I think the industry is going and why. In my experience, solid models help in the following areas: [...]
Compliance With ASME VIII-1, Paragraph UG-22 Internal and external design pressures are not the only criteria used when designing pressure vessels. ASME VIII-1, paragraph UG-22, requires that all external loads acting on the pressure vessel be taken into account as well. These include forces and moments that arise from attached piping and equipment, the [...]
Enter Component Thickness in Rating Input Mode Rating input mode in COMPRESS calculates the MAWP and minimum thickness while allowing you to input your existing geometry. Inputs are re-evaluated during the modeling process and updated as necessary to reflect applicable Code dependencies. In selected circumstances warnings and good engineering practice reminders are presented. [...]
COMPRESS eliminates the time-consuming, manual iteration required by other software. In design mode COMPRESS selects sizes, thicknesses and ratings to meet Code requirements. Inputs are re-evaluated during the modeling process and updated as necessary to reflect applicable Code dependencies. In selected circumstances warnings and good engineering practice reminders are presented. Read About Rating Mode [...]
We often hear the following questions from our clients: "I need to re-rate an old vessel but the Code material is no longer in Section II, Part D. What do I do?" "How can I use new Code Case materials in COMPRESS?" "How do I get non-ASME materials into [...]
Use these 5 tips to save time when designing vessels and exchangers with COMPRESS. Quickly navigate using the shortcut keys: Insert - Insert a component Delete - Delete a component F2 - Nozzle design Ctrl + F3 - Run FEA on nozzles F3 - Generate reports F4 - Edit a component F7 - Set [...]
Vessels From Specification to Detailed Design in Three Easy Steps Creating an ASME design that simultaneously considers internal pressure, vacuum, MDMT and wind/seismic loadings can be a daunting task. The COMPRESS Vessel Wizard can do this for you with minimal data entry. Based on your inputs, design conditions are automatically satisfied by the [...]
COMPRESS Support For Multiple ASME Code Editions Multiple ASME Editions and Addenda (1995 - present) are available within COMPRESS to enable users to easily update older designs to be compliant with the latest Code rules (ideal when providing re-order/replacement designs). To ensure the integrity of the result, only material properties specific to the [...]
Working with Multiple ASME VIII BPVC Editions New ASME VIII BPVC projects typically require the use of the Code Edition in force at the time the contract is signed. When re-rating existing vessels the NBIC allows the use of either the ASME VIII Addenda in force when the vessel was built or the [...]
