Description
Heat Exchanger TEMA Sheet: Mechanical Design β method, governing standards and output schedule
The Heat Exchanger TEMA Sheet: Mechanical Design sizes the heat transfer surface required for a specified duty and checks the mechanical adequacy of the exchanger components, reporting the surface area provided against the area required together with the driving temperature difference actually available. It is applied during detailed design, during design verification by a second engineer, and again during in-service assessment when the operating basis changes. Because every intermediate quantity is reported rather than only the final answer, the calculation can be checked line by line against the governing standard without re-deriving it.
This 3D-LABS workbook is built to TEMA. You supply 1 input and the sheet reports 6 results, with every formula left visible so each figure can be traced to the clause it comes from.
Method of calculation
Duty is fixed from the process stream flow, specific heat and temperature change, the log mean temperature difference is computed and corrected for flow arrangement by the factor F, and the required area follows from Q = UΒ·AΒ·FΒ·LMTD. Where terminal temperatures are unknown the NTU-effectiveness formulation is used instead. Mechanical checks size tubesheet, partition plate and header components per the applicable TEMA and code rules.
Governing standards and references
- TEMA β TEMA Standards of the Tubular Exchanger Manufacturers Association
- ASME BPVC VIII-1 β ASME Section VIII Division 1 for the pressure-retaining components
Each formula cites the clause it comes from on the same row as the result it produces, so a reviewer can check the sheet line by line against the standard.
Acceptance criteria
For the calculation to be reported as acceptable, area provided must exceed the area required at the fouled condition with an agreed over-surface margin, pressure drops must remain within the allowances, and all mechanical components must satisfy the governing code.
Who uses this calculation
This calculation is used by process and thermal engineers specifying exchangers, vendors preparing TEMA data sheets, and reviewers checking exchanger rating submissions.
