Complete Tube Heat Exchanger Design Procedure

1. [PDF] DESIGN AND RATING SHELL AND TUBE HEAT EXCHANGERS

In the US, we specify both the thermal and mechanical requirements for a STHE to an experienced fabricator. The specification includes items such as material types, maximum pressure drop (both sides), preferred tube sizes and maximum design pressures and temperatures. Only one thermal design condition (the rated condition) is used to size the unit

A TEMA datasheet is most often used to specify all of this information.

The fabricator then uses verified computer software to iterate to a final design for pricing.

It is possible to perform the design by hand, but most develop or purchase the software.

Have you ever designed a STHX by hand before ?

What codes and standards will be used in your designs ?

You finalise your basic requirement of heat exchanger before going for the comprehensive design procedure.

You can go through TEMA and I hope it will help you.

A complete procedure would consist of dozens (if not hundreds) of pages, and therefore would not fit into a few forum postings. The best way to do this is to find out what standard your local jurisdiction follows, and then purchase a copy of it.

Well, the best <...procedure...> is to open a dialogue with those that specialise in manufacturing <...tube & shell heat exchanger...>. These vendors are doing it all the time, and there is no need to reinvent the proverbial wheel.

One might start with the trade name labels attached to other <... tube & shell heat exchanger...> units at the facility. These vendors have already established a technical and commercial relationship with the facility.

Once that is done, add in the two fluids' details, such as composition, temperatures, pressure and flowrates.

The next thing to do is to pick up the telephone, and see where it goes from there.
