THERMAL ENGINEERING TOOL
Insulation Thermal Calculator
Estimate heat loss / heat gain, outer surface temperature and a preliminary insulation thickness for industrial piping.
ENGINEERING BASISASTM C680Preliminary web estimator
System Inputs
Use actual product thermal conductivity and approved project conditions for design calculations.
What this tool follows: ASTM C680 is a practice for estimating heat gain/loss and insulated-system surface temperatures. The current active ASTM listing is C680-23a. This website tool is a preliminary estimator, not a licensed copy of the ASTM/NAIMA 3E Plus calculation engine.
RESULTS
Heat Transfer—per metre of pipe
Outer Surface—estimated jacket surface
Annual Energy—per metre / year
Uninsulated Heat—reference condition
Preliminary thickness guidance

Results are indicative. ASTM C680 notes that applicability and accuracy depend on qualified engineering judgment and the quality of thermal-property and system data. Final thickness, condensation control, personnel protection and project compliance must follow the approved specification and applicable codes.
