Shell and Tube Heat Exchangers:
Tubes
- Calculates number of tubes/shell ID
- Changing the material on tubeside, focus of the model changes to a different location in the model
- Corrosion allowance for the tubes in ASME design
Tubesheet
- "Use EN 13445 Annex G/EN 1591" option is greyed out
- Different material selection for a Stationary Tubesheet vs. Floating Tubesheet
- Use the Tube sheet Design Conditions dialog
- Set the design conditions for tubesheet
- Input extra cladding thickness on tubesheets
- Manage the number of Tubesheets
- Difference between tubesheet design condition and design case
- MMT (Mean Metal Temp) for Fix tube sheet Heat Exchanger
- Automatically update the tubesheet design conditions when the heat exchanger design conditions are changed
- Input values for and enable / disable differential pressure option
- Axial tube stress and Tube to tubesheet joint check for U-tube tubesheet
- Program does not use both Tubesheet thickness in calculations
Tube Bundle Layout
- See the pass order number and modify it
- Number of passes and Partition Plates are not defined correctly
- Tubesheet layout not full of tubes?
- Specify shell ID instead of tube numbers in modeling the tube layout
- Tube Bundle report is not aligned with bundle layout
- Number of tubes and path are different in report
- Relocation of the pass partition is reset when clicking on "compute" (heat exchanger)?
Import
- Import Aspentech edr file
- Imported HTRI model with 360 tubes, however AutoPIPE Vessel suggest only 332
Support
Modeling
- Shell length for heat exchanger
- Shell length interpreted
- Define shell length in different types of Heat Exchangers
- Manage baffle spacing of a heat exchanger
- Input a specific Baffle details
- Manage the baffle spacing of a heat exchanger?
- Change the corrosion allowance for clad bottom plate on a heart exchanger
- Design a stacked heat exchanger
- Design heat exchanger with shell dimension based on nominal pipe size
- Connect two different shell radius that have a 50 mm gap
- Cannot choose a "Double Segmental" baffle type for a BFM heat exchanger
- Gasket under the pass partition in a heat exchanger is not possible
- Add different gasket In gasketed Tubesheet connection In AES Heat Exchanger
- Heat Exchanger Floating head, Split ring / Splices per TEMA Style A and B, dim. B details
- 8" nominal shell size the O.D. is reflected as 8.78" O.D. (it should be 8.625")
- "Mechanical cleaning" option locked even if the option is unchecked?
- Use TEMA Metric Bolt Root Area (TEMA Table D-5M) from section 9.
- Creep and Fatigue data on Heat exchanger
- Heat Exchanger Geometry
- Heat Exchanger Pass Partition Plate Modification
- Insert the shell connection on the head of a heat exchanger
- Settings for DIC and OTL on the harness tab
- Baffles are deleted when deleting a Nozzle element
Analysis / Calculations
- Calculate Maximum shear load;Qi
- Calculate Combined Shear load
- Calculate MAP (New and cold)
- Calculate the shell length at the time of design
- Stresses are very high and failing in shell/channel joint when split the shell in 3 parts
- ASME 2019 - appendix A-2 calculation for Tubesheet with tubes expanded + seal welded not performed
- Different effective diameter formula in operating and hydrotest condition (tube side) compared to hydrotest condition shell side
- Calculate the Hydrotest MAWP on both the Shell and Tube side
