The full TEMA-class designation — explicitly governed by the Tubular Exchanger Manufacturers Association's mechanical design standard, across Class R, C, or B depending on service severity.
| Application Scope | Standard shell-and-tube construction under full TEMA governance |
| TEMA Class Options | R (severe petroleum), C (moderate), B (chemical process) |
| Structural Type | Any — Fixed, Floating, or U-Tube, per TEMA class requirements |
| Governing Codes | TEMA (primary), ASME Section VIII Division 1 |
The TEMA class you specify drives the design margin, not the structural type or material choice.
This designation specifically invokes full TEMA mechanical design governance — Class R, C, or B — while the generic label doesn't commit to a specific code class. In practice, most real exchangers are built to full TEMA anyway.
Class R suits severe petroleum and related process service, Class C suits generally moderate service, and Class B suits chemical process service — see the full comparison on the Standards pillar for design margin differences.
No — TEMA governs the mechanical design specific to shell-and-tube construction, typically applied alongside ASME Section VIII for the pressure vessel aspects of the shell.
