The Standards are set by members of the Technical Committee of TEMA. TEMA does not give or recommend thermal-hydraulic design methods, leaving it to the individual company to use their own methods or one of the published or commercially available computer-based methods.Įven though TEMA has only about 20 members (who must meet strict standards of in-house thermal-hydraulic and mechanical design capability, manufacturing accountability, and quality control to attain membership), practically all shell and tube heat exchangers for the process and related industries are specified to meet TEMA standards of construction. General Information (e.g., dimensions of pipe, tubing, fittings and flanges pressure-temperature ratings conversion factors, etc.) TEMA Standard gives various types of constructions which are all well within the Design and Manufacturing scope of PECPL for the complete range of Pressure and. Thermal Relations (includes fouling and charts of the configuration correction factor on the Logarithmic Mean Temperature Difference) A fixed tube sheet heat exchanger has straight tubes secured at both ends to the stationary tube sheets that are welded to the shell. Mechanical Standards TEMA Class RCB Heat Exchangers Types of Shell and Tube Heat Exchangers Fixed Tube Sheet TEMA Type M. General Fabrication and Performance Information TEMA is a set of standards developed by leading heat exchanger manufacturers that defines the heat exchanger style and.
