Pipe Thermal Insulation Calculator

Suppose we have a pipe of diameter 12 with hot oil at a temperature of 200 c flowing through it.

Pipe thermal insulation calculator.

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. 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. Allowed heat loss per meter of pipe is 80 w m.

To calculate the insulation thickness it is necessary to know or define the line and ambient temperatures and the relative humidity and to determine the thermal conductivity and heat transfer coefficient of both the insulation and the object pipe duct etc to be insulated. The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow. Estimate the amount of insulation needed for a wall. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.

Estimates heat loss from an insulated and bare horizontal steel pipe along with calculation of surface temperature. Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. This calculator has options for 3 different wall heights. The amount of coverage of one bundle of batt s differs by manufacturer.

It is typically used in process piping and chiller plants and performs best in applications below 50 f. Personnel protection calculator for horizontal piping. In many times pipe insulation additionally minimizes the effect of the temperature of the pipe at the instant environment. 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.

The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. 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. Input requirements include the pipe size operating. 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.

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