Using Tees in COMPRESS

Tees (branch connections) can be an excellent way to reduce pressure vessel welding and material costs.  COMPRESS provides the ability to use tees as shell components.  COMPRESS models also support tees attached to nozzles.

Tees are treated as ASME B16.9 rated components and Appendix 1 calculations are performed for each tee.

COMPRESS Pressure Vessel Design Highlights

 Pressure vessel nozzles Nozzles Simplify the detailing of nozzle attachments with flexible and intuitive nozzle design capabilities. Finite Element Analysis Built-in Finite Element Analysis (FEA) for Nozzles and TEMA Flanged and Flued Expansion joints. FEA Nozzle API 650 Storage Tanks Modeling storage tanks is easy as COMPRESS guides you through an intuitive design wizard. API 650 in COMPRESS Vacuum Rings Drag-and-drop vacuum rings and quickly see how the external pressure rating changes. Vacuum Rings in COMPRESS Quick Design Speed up the process of pressure vessel modeling with Quick Design mode. COMPRESS Quick Design Mode Productivity Software packages like COMPRESS exist to increase productivity and save Engineering hours. Heat Exchanger Perform ASME UHX and TEMA calculations and transfer these designs to your estimating and drafting departments. Heat Exchanger designed in COMPRESS Division II Many companies use the alternative rules of Division 2 because of the cost savings, versus Division 1. Division 2 option in COMPRESS MDMT Rules of UCS-66 The rules of UCS-66 guard against vessel failure by brittle fracture, a low probability high consequence event. MDMT Rules of UCS-66 External Pressure Design Simplify the complexity of
UG-28 rules for external pressure of 15psig and greater. Jacketed Vessels Design both conventional and half pipe jacketed vessels as a standard feature in COMPRESS. Vessel Wizard The Vessel Wizard speeds pressure vessel design by creating complete pressure vessel models with minimal input. COSTER Import files from COMPRESS and create user customizable pressure vessel cost estimates in spreadsheet format. Bill of Materials generated from COSTER Flange Design Create optimized Appendix 2/ASME B16.5/16.47 flange designs with minimal time and effort. Flange design in COMPRESS Weld Seams Designers can visually confirm good practices such as staggered longitudinal seams. Weld seam wizard in COMPRESS Lifting & Rigging Use an accurate weight, the correct center of gravity, and apply the actual section properties. Lifting mechanics in COMPRESS Modeling + Drawings The Codeware Interface includes Drafter 3D, a feature that auto-generates 2D pressure vessel drawings. Drafter 3D from Codeware True SOLIDWORKS models created automatically from the Codeware Interface True SOLIDWORKS Models Sketches, operations and drawings can be manipulated as if the model had been created manually in SOLIDWORKS. Related Codes COMPRESS implements a wide range of related engineering methods, codes and standards. COMPRESS includes related engineering methods, codes, and standards Design Mode Save time by reducing the trial and error iterations that would otherwise be required when designing pressure vessels. Design mode in COMPRESS Rating (Analysis) Mode The COMPRESS Rating Mode takes your design and determines the vessel’s MAWP, MAEP and MDMT. Rating mode in COMPRESS Hydrotest Performing hydrotest stress calculations in the design stage prevents equipment damage during hydrotesting. Hydrotesting in COMPRESS Hillside Nozzle COMPRESS saves time by calculating chord openings and governing planes of reinforcement automatically. Hillside Nozzle design in COMPRESS ASME Editions Older ASME Codes are retained in all COMPRESS releases so you can always use the latest software. 2023 ASME VIII Code Edition in COMPRESS Automatic Liquid Levels COMPRESS eliminates the need to manually calculate each vessel component’s liquid static head. Automatic Liquid Levels in COMPRESS Global External Loads The Loads Menu allows designers to easily consider global external loads when sizing pressure vessel supports. External Loads in COMPRESS Clips and Lugs Designers can quickly include the mechanical effects of pressure vessel internals and attachments in their designs. Clips and Lugs designed in COMPRESS Stacked Vessels Certain industrial processes require pressure vessels with multiple chambers operating under different design conditions. Multi chamber pressure vessels in COMPRESS Appendix 46 Produce more economical Div 1 pressure vessel designs with increased accuracy from the Div 2 design by rule equations. Appendix 46 in COMPRESS Manufacturer's Data Reports Simplify the creation, submission and management of ASME Manufacturer’s Data Reports and NBIC Repair and Alteration Forms. ASME Manufacturer's data reports in COMPRESS Support Skirt Openings Specify piping connections to vertical vessels that require additional piping and openings cut out of the support skirt. Support Skirt Openings in COMPRESS Foundation Loads Summary Break down the loads for the specified vessel operating conditions including weight, wind, seismic, and vortex shedding. Foundation Loads Summary in COMPRESS Shipping Saddles Shipping Saddles in COMPRESS COMPRESS provides a shipping saddle option based on the industry standard Zick Analysis. UG-80 and UG-81 COMPRESS automatically provides out-of-roundness tolerances that must be maintained during pressure vessel fabrication. UG-80 and UG-81 design in COMPRESS Nameplate Design Every pressure vessel is required by Code to have a nameplate. COMPRESS handles this by including a convenient nameplate option. Nameplate design in COMPRESS Fatigue Screening Quickly enter fatigue data and make performing VIII-2 or Appendix 46 Fatigue Assessments simple.
