ASME forms for Air Cooled Heat Exchangers

ASME forms for Air Cooled Heat Exchangers

(OP)
Hi,

Just one quick question. When manufacturing an Air Cooled Heat Exchanger (inlet header, outlet header, finned tube bank cooled by air) should I be completing an ASME U-1A or ASME U-1 form?

Getting different answers from different people and would like to resolve it before we complete fabrication.

Thank you

Brian

RE: ASME forms for Air Cooled Heat Exchangers

U-1 is all-encompassing. U-1A is the 'short form' for simple vessels. If both of my box headers were the same size, and the tubesheet and plugsheet were the same thickness, I would use the U-1A. Simplified form for a simple piece of engineering.

however, YMMV & 'ask your Authorized Indpector'.
