Calc to heat exchanger with cast iron head
(OP)
How to do calc to heat exchanger Shell & Tube (Type BEM) with cast iron head? this is possible using some code for example ASME UCI?
P.S. In brazil is obligatory heat exchanger to be in accordance with some rules for construction of heat exchanger, where and how i can to do this calc?

Everywhere, including Amazonas jungle, the heat exchanger must be designed in accordance with a recognised pressure vessel code, like ASME.
First, the heat exchanger has to be designed to perform the process requirements (heat exchange), most likely using an appropriate software like HTRI, Aspen, etc.
Then, once the basic sizing is done on HTRI, the exchanger components can be designed using a proven pressure vessel design software like Compress, PV Elite, etc.
Before handling these softwares, you need a chemical engineering degree, a mechanical engineering degree and a few years of experience using the software. Otherwise, the exchanger will likely explode and kill someone and you end up in a famous Brazilian jail for the rest of your life (if they let you live).
Best advise, if you are not familiar and experienced design engineer in this field, hire someone expert in the field and everyone will be a winner.

If you think about it, a 2-pass Hx head requires:
2 double-sided fillet welds for the 'pass-plates'
2ea cirumferential seams - head-to-shell [that small slice of pipe on a Ch Hd is 'shell'] and Ch-shell to flange
and 2ea nozz welds - inlet and outlet.
This is a lot of hand-work that one casting eliminates.
