Pipes - Insulated Heat Loss Diagrams
Heat loss (W/ft) diagrams for 1/2 to 6 inches insulated pipes - ranging insulation thickness 0.5 to 4 inches and temperature differences 50 to 350 degF.
The heat loss diagrams below is based on metal pipes with fiber glass insulation, thermal conductivity 0.25 Btu/h oF ft2/in and outdoor condition with moderate wind 20 mph. A safety factor of 10% is included.
- indoor location - reduce values with 10%
- mineral wool insulation - increase values with 6%
- rigid cellular polyurethane - reduce values by 30%
