Heat exchanger manifold design 2

[jj_550]

Hello,

I have a heat exchanger, for which I need to recalculate the manifold which is square cross section. For the calculation I must find a norm or standard (ASME, ASHRAE TEMA) to support the calculation memory. Please do you know where I can find this norm or standard?

jj_550, one possible source is ASME Sec VIII, Div 1, Appendix 13 for non-circular vessels. So you know, people are rarely happy with the results

Not familiar with the term "calculation memory".

Is your HX stamped, have a nameplate or otherwise traceable to a recognized Code or standard? You know exactly what it is made of? Is it a lab vessel?

Regards,

Mike

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

Hi Mike,

No, the Hx is not stamped, the idea is to verify with a standard if the collector meets any design standard. It is made of Stainless Steel, and it is located in an industry.

As Mike suggested, ASME VIII-1 Mandatory Appendix 13.
Another (great) option is to use EN 13445-3 chapter 15. It covers more than the ASME App.13 and has better explanations.

If not stamped you would apparently have freedom to select the design standard that suits you best. A problem you may run into is to determine allowable stress(es). Typically mandated by the Code.

You say "Stainless Steel" but for example under ASME Code you need to know both the exact alloy and product form. 316 / 316L 304 / 304L etc. Pipe, plate, tubing, etc.

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