If possible, design all heat exchanger components before adding the tubesheet. This will allow these components to be brought in to the tubesheet during the design process. This will increase the accuracy of the information and the speed of creation.

Make sure the values for Tsm and Ttm are as accurate as possible. Though inflating values is considered more conservative for design temperatures, this is not the case with Tsm and Ttm. The difference between the Tsm and Ttm values is important. The bigger the difference, the higher the load, so it is more conservative to estimate a larger difference.

Enter the tubesheet thickness you believe is accurate. Click the status button and review the information. If the tubesheet is failing, review the guide on Troubleshooting tubesheets.
