Modeling Heat Exchangers in COMPRESS

Modeling Heat Exchangers in COMPRESS is easy and efficient. COMPRESS provides a wizard for a user to enter in clients specifications. The heat exchanger wizard designs the complete exchanger: tubesheet(s), tubes, expansion joint, shell, channels, flanges, head closures and nozzles. Up to eight design and/or hydrotest conditions may be specified. All conditions are investigated simultaneously which includes the various load condition for each design condition as stipulated in the ASME Code.

ASME & TEMA Code Compliance

The heat exchanger components may be evaluated using ASME UHX, TEMA, or both ASME UHX & TEMA. The ASME UHX & TEMA option provides the tubesheet design thickness from both design codes allowing the nominal tubesheet thickness assignment to be based on either set of design rules.

The governing design condition determined by COMPRESS is automatically used for the vessel component ASME VIII-1 calculations (e.g. shell, channels, head closures, nozzles).

Seamless HTRI Integration

Users can take advantage of the bi-directional interface COMPRESS has with HTRI. This pulls in data specified in HTRI so there is no duplication of inputs on the mechanical design side.

Featured Heat Exchanger Design Capabilities

Efficient Modeling Simplify heat exchanger design with a guided workflow and built-in ASME and TEMA code compliance. Design Conditions Simplify complex heat exchanger design by allowing multiple operating conditions to be evaluated simultaneously, including true MAWP determination. Tube Bundle Streamline tube bundle replacement by modeling and analyzing only the bundle without recreating the full exchanger. Multiple Codes Supports multiple ASME and TEMA code editions, automatically applying the correct allowable stress values for each. Flange Design Automate complex flange analysis by accounting for shared bolting, governing loads, and iterating conditions to determine accurate MAWP. FEA for Expansion Joints Integrated FEA for TEMA expansion joints, enabling fast, automated analysis with minimal setup and optimized performance. Lift Lugs for Channels Enable lift lug design directly on exchanger subassemblies, eliminating the need to recreate components in separate files. ASME Reports Generate comprehensive, easy-to-navigate ASME calculation reports covering all design and hydrotest conditions. ASME PCC-1 Appendix O Evaluate bolted joints per PCC-1 Appendix O, determining optimal bolt stress and torque while ensuring gasket, bolt, and flange integrity.
