Pipe Thermal Insulation Calculator

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.

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. 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. 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. 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.

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. It is typically used in process piping and chiller plants and performs best in applications below 50 f.

Maximum allowed insulation temperature at the outer wall is 50 c. Allowed heat loss per meter of pipe is 80 w m. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c.

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. 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. Personnel protection calculator for horizontal piping.

Input requirements include the pipe size operating. Suppose we have a pipe of diameter 12 with hot oil at a temperature of 200 c flowing through it. 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.

The amount of coverage of one bundle of batt s differs by manufacturer.
