Use case

For mechanical and design engineers.

For engineers who design heat exchangers and pressure vessels: the whole exchanger in one model, and the freedom to try an idea and see its effect.

A bar chart of three bolt sets against the required bolt area of 29.88 in²: 60 bolts of 1 in give 33.06 in² (OK); 60 bolts of 7/8 in give 25.14 in² (needs attention; a larger bolt size or more bolts is suggested); 72 bolts of 7/8 in give 30.17 in² (OK). — Open the drawing at full size

A new exchanger

From the datasheet to the calculation package.

Take the reference exchanger: TEMA AET, a 40 in shell, and 554 tubes. From its datasheet, PlutoHX designs its shell and channel, the covers and nozzles, the girth flanges and their bolts, and the tubesheets, then generates the calculation package that goes with them.

The shell to UG-27, with its MAWP and hydrostatic test
The heads to UG-32 and the flat covers to UG-34
The girth flanges to Mandatory Appendix 2
The tubesheets to Part UHX

A what-if on the bolting

Try an idea, see the effect.

Suppose you try 7/8 in bolts in the girth flange to save cost. PlutoHX shows at once that the bolt area is now below the required area, and suggests the fix. With 72 bolts of 7/8 in, the requirement is met again.
