Complete Heat-Transfer Design Sequence
Standards and limitations
- API 660: project requirements for shell-and-tube exchangers in refinery service.
- API 661: project requirements for air-cooled exchangers.
- TEMA: shell-and-tube nomenclature, mechanical classes and controlled design requirements.
- ASME Section VIII: qualifying pressure-boundary mechanical design, fabrication, inspection and testing.
- Final thermal design requires validated properties, phase behavior, fouling, pressure-drop and vibration review using approved vendor software such as HTRI or Aspen EDR.
Important: Results are preliminary. Verify temperature approach, phase behavior, fouling, pressure drop, materials and mechanical-code requirements before issuing a datasheet.
