Thermal Analysis and Heat Transfer Calculations
High temperatures and temperature changes cause expansion, stress and energy loss. SLETEC calculates temperatures, heat loss and thermal stresses so equipment works safely and efficiently.
Services include steady-state and transient thermal FEA, thermal-stress analysis, conjugate heat transfer CFD, insulation thickness and heat loss (ASTM C680), tank heating and cooling time, and heat exchanger duty checks.

Frequently Asked Questions
Why is my equipment cracking after heating?
Repeated heating and cooling can cause thermal fatigue. A thermal-stress analysis shows the cause and the fix.
Can you calculate insulation thickness?
Yes. We calculate insulation thickness for heat conservation, personnel protection and condensation control.
Do you do thermal CFD?
Yes. We model heat transfer with fluid flow in equipment, rooms and enclosures.
