Heat Exchanger design in PVElite
U-tube Tubesheet Capabilities
Floating Tubesheet Capabilities
General Tubesheet Capabilities
Moment from bolting of the Tubesheets to the shell/channel flanges is considered in the design. Tube-Tubesheet joint is checked per ASME App-A and part UHX, and PD5500. Tube-Tubesheet weld can also checked per ASME.
PVElite computes the stress at the actual tubesheet thickness and the required tubesheet thickness for given loading. Where required it calculates the shell/channel stresses. If an expansion joint is specified (for a fixed tubesheet) then its spring rate and stresses are also computed and the spring rate is considered .
There is an option to specify up to 8 different load cases at one time. These load cases can have different design temperatures, mean metal temperatures, pressures etc. User can also override the material properties such as coefficient of thermal expansion and Young's modulus.

PVElite performs the mechanical design of heat exchangers in accordance with the following Codes:
- ASME Section VIII Division 1 (part UHX, formerly App. AA) code
- TEMA standard
- PD 5500 (formerly BS5500, British standard)
Fixed Tubesheet Capabilities
- Fixed Tubesheet can be designed per ASME, PD5500 and TEMA codes.
- Plain Shells, and Shell with Expansion joints or Bellows can be modeled.
- Stress due to differential thermal expansion of tubes and shell is computed.
- Flanged and Flued (thick) Expansion Joint can be designed per TEMA and ASME.
U-tube Tubesheet Capabilities
- U-Tube exchangers can be designed per ASME, PD5500 and TEMA codes.
Floating Tubesheet Capabilities
- Floating Exchangers can be designed per ASME, PD5500 and TEMA codes. e.g. packed, sealed etc.
- Floating head covers can also be designed per ASME and PD5500.
- Stress due to differential thermal expansion of tubes and shell is computed.
