Heat Exchanger Design: Tema Standards Heat Exchanger DesignA copy of the licensing agreement accompanies the software. Tubular Exchanger Manufacturers Association, Inc. The 9th Edition retains the useful data and features found in the Eighth Edition plus many clarifications and innovations. Some noteworthy features of the Ninth Edition include:. New rules for flexible shell elements expansion joints , which are based on a Finite Element Analysis FEA approach Tables for tube hole drilling have been expanded to 3 diameter tubes Guidelines for performing Finite Element Analysis FEA had been added.

TEMA 1978 Standards Of The Tubular Exchanger Manufacturers Association, 6e
TEMA also produces software for evaluation of flow-induced vibration and of flexible shell elements expansion joints. Worldwide, the TEMA Standard is used as the construction standard for most shell and tube heat exchangers   . The standard is composed of ten sections: . TEMA's standard recognizes three separate classifications of exchangers   . Each class has different mechanical construction requirements, based on the expected service. Those classes are:.

These standards are based upon sound engineering principles, research, and field experience in the manufacture, design, installation, and use of tubular exchangers.

The Standards are regularly updated and published; the most recent edition is the seventh, published in Most shell and tube exchangers ordered by the process industries and for other high-severity applications throughout the world are built to TEMA standards. To quote from the Standards p. Class R for the severe requirements of petroleum processing and usually including most large scale processing applications. There is in fact relatively little difference between the Standards for the three classes; where there are differences, Class R calls for heavier and more conservative construction features, and Class B since these are usually stainless steel or high alloy exchangers gives some allowance for lighter i. Thermal Relations includes fouling and charts of the configuration correction factor on the Logarithmic Mean Temperature Difference. General Information e.
