Chilled water pipe insulation thickness calculation formula.

This calculation determines the ideal thickness of water piping insulation for efficiently and economically preventing a heat transfer from outside to inside and keeping the water transported within cool it does not determine the thickness of insulation designed to keep condensate or other fluids from losing heat. Extra margin must be taken on insulation thickness as sometimes conducting heat transfer through insulation may become higher than convective heat transfer due to air on outside wall of insulation. Insulating chilled water systems requires special attention. The heat loss from steam per meter of pipe length has to be.

Hence insulation thickness ri rp 0 2302 0 1524 0 0777. The calculator is generic and can be used for both si and imperial units as long as the use of units are consistent. For below ambient service by contrast the new pipe insulation thicknesses are not particularly noteworthy. D o outside diameter m in d i inside diameter m in ρ m density of piping material kg m 3 lb in 3.

2 0 role of pipe insulation for chilled water systems 33 f to 60 f 0 5 c to 15 6 c pipe insulation for chilled water systems is specified and installed primarily for process control condensation control and energy conservation. Minumum insulation thickness preventing condensation for pipes parameters ambient temperature ta c 30 medium temperature t m c 6 to prevent condensation tube diameter mm 114 insulation material r flex st relative humidity 70 results thermal conductivity w mk 0 0375 dew point temperature t d c 23 9 minimum insulation. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. Cooling and heating load excel sheets free excel sheet for calculating pipe insulation thickness.

Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. Chilled water pipes emit heat all the time so they must be insulated and this excel sheet calculates heat loss and insulation thickness. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k. Industrial insulation phase 2 8 insulation thickness thermal conductivity performance criteria revision 2 0 august 2014 3 0 calculation of material thickness to achieve heat loss values 3 1 heat loss calculations pipe insulation is thermal insulation used to prevent heat loss and gain from.

Insulation thickness 77 7 mm. This calculator can be used to calculate the weight of a pipe with or without liquid. Heating cooling pro standard. Weight of pipe calculator.
