TEMA required?
TEMA required?
(OP)
When is it required to design a heat exchanger to TEMA standards? I am installing a condenser on top of a condensate tank to knock down steam being relieved from the tank.

RE: TEMA required?
However, the term 'tank' you are using is a bit vague, at the best. Tank is a storage equipment designed to API 650/620 or similar and is not used for steam generation. Perhaps you are talking about a pressure vessel relieving some steam which you wish to condensate in a knock-out drum or similar. In that case you don't need a heat exchanger at all.
Could you come back with some more details?

Condensers generally need an air removal section so that the non condensables don't air bind the heat transfer surfaces.

RE: TEMA required?
I have designed and had constructed several large exchangers - always to TEMA. A "steam system" vendor gave me a quote for a condenser to handle this, but when I asked them to send me a TEMA spec sheet they balked - stating that their fabricator could not handle - and expect the cost to triple. None of this makes sense to me.

It is unusual, as you can see from the above replies, the condenser to be configured as a shell and tube exchanger. However, if you insist on this design, the 75 psi design pressure would warrant a TEMA + ASME VIII Div 1 design. Also demin water on the cooling side??? I can see that at least to you the bad economical times went past leaving daisy petals on your foot path. If you can afford the cost, ditch the miserable carbon steel tubes, the Superduplex ones will last you a life time (otherwise the demin water will corrode the proverbial out of your tubes).
You might be right, the little cheap Heliflow will never look as impressive as a massive, expensive shell and tube exchanger. Imagine the shiny saddles chromium plated....! Stainless Steel anchor bolts, pink painted nuts...By the way, the word nuts reminds me of something...
