Thanks

For example ASME B 16.5 establish the dimension of five types of flanges but all are RF or FF but no male, female groove. NPS 20 WN female type was the size in my case.

Sometimes time saving & as per our experience making RF flange to female face flange is cheeper than purchasing the new female face flange ..
ASME B 16.5 does not only contain WN, SO, Bling, Threaded & SW flgs?

Can anybody advise me about following

1- Use of ASME standard flanges with litle modification like machining e.g. making groove on face, making female/male flanges by purchasing RF flgs, making holes in blinds flgs specially in Heat Exchangers. Need to recalculations of flanges according to App. 2 ...

Yes Ashfaq bhai, i need some mechanical drawing of floating head, double pipe, hairpin heat exchanger because in TEMA you can just view a sketch. Thanks alot.

Thanks to Ashaf bhai, Ben & Mechlor for your suuport i have gone through manual calculations & TEMA, feel quite better than before.AEM, AEU but still feeling not confident on special type heat exchangers (hairpin) for flaoting head/tube sheet heatexchanger. i am looking for drawing or small catalogs ...

referece to attached design calculation provided by Ben, can you provide me some pics of shell & tube HE, tube to tube sheet joint selection & tube sheet to shell joint as i am having problem in practical visualization.

@BenThanks for you People support.
@Ashfaq Bhai its both TEMA and ASME SEC VIII Part UHX, Design cord according to Client specifications.
I`ll go through these calculations and revert back to you in case of any confusion.

AOA, I want to learn manual as well as software based PV Elite calculations of above listed items as its quite different from Pressure Vessel. So any body can HE thermal & mechanical design can provide me some standard, literature & contact details as its part of my JD now
