Examine printed output and learn how to evaluate the reports.
Adding the rest of the shell components. Shell flanges at cover, shell cover cylinder and head. With these components the heat exchanger body is complete.
Adding the rest of the channel components. Channel cylinder, body flange at cover, and channel cover (blind)
Proceed in calculating a floating head attached on the floating tubesheet. Typical AES formation.
Create a tube bundle and evaluate it. Attach the bundle on the stationary tubesheet and proceed in creating the floating tubesheet.
Learn how to intersect the tubesheet among the shell and channel body flanges. Learn how to create a tubesheet.
Calculate the channel flange at tubesheet. Along with the shell flange, these two entrap the tubesheet. See how the flanges affect each other. Calculate both flanges for the worst case scenario.
Calculate the main shell and the first flange connected on the stationary tubesheet of AES heat exchanger. Use rigorous flange analysis.
