AKR module
For product heating or cooling in pressure vessels, double jacket construction is common in addition to welded-on pipe coils. The advantage of the double jacket is the uniform and thus improved heat transfer. However, the strength calculation is more complex than with welded-on pipes. The endangered outer shell brim and above all the transition from the brim to the vessel shell must be subjected to a stress analysis.
The AKR module calculates the stress for the knuckle of a jacketed shell and for the transition to the pressure vessel. The module can differentiate between drawn-in and braided knuckles. Both the upper and lower end knuckles are taken into account. The program offers a graphical representaion of the geometric conditions, so that single input and output data can also be presented figuratively.
