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%
