I'm now in the phase of studying the design calculations for boilers in general, without having a specific design.
Coming from generic Pressure Vessel design, it takes some time to get acquainted with boiler specifics. However, thinking it over somewhat more, I now see that it is not...
The following figure illustrates what I mean with laying the VDI graph lines (figure (B) ) on top of the Fourier transform result (figure (A) ): Link

Dear community members,
After having searched in several books and on the internet for a good reference, I must conclude that a good description to assess measured vibrations is difficult to find.
Suppose the goal is to perform a pipe vibration measurement and subsequent assessment. The...
Thanks for your contributions Fizza453 and marty007.
Especially the point made about the heat transfer coefficients is a good point. Indeed, the tubes will have a temperature close to the shell and differential expansion will be minimal. I'm curious to find out the maximum temperature...
After doing some more reading, it seems to me that everything that is not covered by Section I, like the thermal loads on the tubesheet, is covered by PG-16. This paragraph tells that when design rules are not given in Section I, you have to come up with an appropriate analysis method yourself...
When I have a tubesheet in a boiler, it will be subject to both pressure loads and thermal loads. Pressure loads are well covereed in Section I by applying rules for flat plates and ligaments. However, there don't seem rules to cover thermal loads on the tubesheet.
Consider the following very...
When using ASME B&PV Section I, some topics are not in Part General, but in one of the specific parts like PFT (firetube boilers) or PWT (watertube boilers). For example:
(*) external pressure is covered by Part PFT (PFT-50 covers some rules for cylinders (tubes) under external pressure). When...
