The general descriptions of the three major TEMA classes are: TEMA C – General Service. TEMA stands for Tubular Exchanger Manufactures Association Process Design of Heat Exchanger: Types of Heat exchanger, process design of shell and tube heat exchanger, condenser, and reboilers The Standards recognize three classes of heat exchanger construction: Class R for the severe requirements of petroleum processing (and usually including most large scale processing applications). TEMA R – Refinery Service. Class C for general commercial application TEMA (Tubular Exchangers Manufacturing Association) is the preferred standard for the manufacture of shell and tube heat exchangers. TEMA B – Chemical Service. Whether having a heat exchanger designed, fabricated Selecting TEMA Type Heat Exchangers TEMA is a set of standards developed by leading heat exchanger manufacturers that defines the heat exchanger style and the TEMA codes and IS Main aim is to check the mechanical stability of the device by calculating parametersand pressure design codes used in heat exchanger design TEMA Class C exchangerThe TEMA Mechanical Standards for Class C heat exchangers specify design and fabrication of unfired shell and tube heat exchangers for The Tubular Exchanger Manufacturers Association, or TEMA, has developed standards that define the design, fabrication, tolerances, installation and maintenance of shell-and TEMA designations of Heat Exchangers. TEMA R is the most demanding standard, while TEMA C is the least This cooperative technical effort creates an extensive network for problem-solving, adding value from design to fabrication. Because of the number of variations in mechanical designs for front and rear heads and shells, and for commercial reasons, TEMA has designated a system of notations that correspond to each major type of front head, shell type and rear head TEMA is a set of standards developed by leading heat exchanger manufacturers that defines the heat exchanger style and the machining and assembly tolerances to be employed in the manufacturing of a given unit.
