Pipe Thermal Insulation Calculator

Personnel protection calculator for horizontal piping.

Pipe thermal insulation calculator.

As described on the midg simple calculators web page this calculator estimates the maximum contact exposure time on the outer surface of a horizontal pipe insulation system based on the potential for contact burn injuries. Calculation is based on the square footage of the walls that need to be insulated divided by the square footage a bundle of insulation batt s covers. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k. Download pipe insulation excel calculator for hvac thermal insulation pipe insulation is designed to assist keeping a suitable temperature for pipes and any fluid flowing via the pipes.

Information concerning a hypothetical insulation system e g the length of run pipe size operating temperature ambient temperature and wind speed insulation material and surface emittance of a proposed insulation system may be input by the user. This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. The pipe calculator estimates the heat flows through horizontal steel piping. Data pipe size inch 0 5 0 75 1 1 25 1 5 2 2 5 3 3 5 4 5 6 8 10 12 14 16 18 20 24 26 28 30.

The amount of coverage of one bundle of batt s differs by manufacturer. Estimate the amount of insulation needed for a wall. Input requirements include the pipe size operating. Thicknesses of thermal pipe insulation used for saving energy vary but as a general rule pipes operating at more extreme temperatures exhibit a greater heat flow and larger thicknesses are applied due to the greater potential savings.

Maximum allowed insulation temperature at the outer wall is 50 c. This calculator has options for 3 different wall heights. Estimates heat loss from an insulated and bare horizontal steel pipe along with calculation of surface temperature. Suppose we have a pipe of diameter 12 with hot oil at a temperature of 200 c flowing through it.

The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. In many times pipe insulation additionally minimizes the effect of the temperature of the pipe at the instant environment. Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. Allowed heat loss per meter of pipe is 80 w m.

Insulation used is glass mineral wool with thermal conductivity for that temperature range of 0 035w m k.
