The heat loss diagrams below can be used as an indication of the heat loss from insulated pipes at various temperature differences. The diagrams are based on

  • metal pipes
  • fiber glass insulation with thermal conductivity 0.036 W/mK
  • outdoor condition with moderate wind 9 m/s

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%
  • Heat loss diagram (W/m)
