Applied rule for Air Fin Cooler
Applied rule for Air Fin Cooler
(OP)
Dear sir,
I want to know correct applied rule for AFC(Air Fin Cooler)
There is fin tube connected between two tube header, As I know this header thickness calculated by ASME SEC.1 not for ASME SEC.VIII Div.1
however, tube ligament efficiency calculation is shown on UG 53 in DIV.1
I wonder which rule is correct for this header thickness calculation.

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Header configuration is circular type not rectangular. Gernerally in HRSG, this header shall be calculated by SEC. 1 However, I was requested it to comply with Div.1 UG53
So I wonder that this is correct

Appendix 13 of VIII-1 has rules for circular headers, see Fig. 13-2(c). In any case the holes for tubes and plugs are multi-diameter holes, and because of that I don't think UG-53 would apply.

For ligaments see paragraph 13-6.
