Pipe Thermal Insulation Calculator

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

Pipe thermal insulation calculator.

Maximum allowed insulation temperature at the outer wall is 50 c. Insulation used is glass mineral wool with thermal conductivity for that temperature range of 0 035w m k. Allowed heat loss per meter of pipe is 80 w m. 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. 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. 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. 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.

Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. 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. It is typically used in process piping and chiller plants and performs best in applications below 50 f.

Suppose we have a pipe of diameter 12 with hot oil at a temperature of 200 c flowing through it. The pipe calculator estimates the heat flows through horizontal steel piping.

Personnel protection calculator for horizontal piping. 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 amount of coverage of one bundle of batt s differs by manufacturer. Estimates heat loss from an insulated and bare horizontal steel pipe along with calculation of surface temperature.

The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow.
