[Kounhetsov]

Dear Experts,

Please advise the code for gas a firing tube heat exchanger. Whether ASME 8 div 1 can be applied or div. 2.
The operating of heating fluid is glycol. Operating pressure 4 bars, heating fluid temperature:120 degree C.

Thanks in advance.

Either.depending on the design and size vs cost.

Why would you ever want to use Div 2 for these pressures? I assume shell side contains glycol.

Dear GenB and weldstan

Thanks for your posts.
@Dear GenB: Can you advise in more details please.
I found out that API 530, 630 and 665 can be gotten for references.

Thanks
