Pipe Thermal Insulation Calculator

Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c.

Pipe thermal insulation calculator.

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. Maximum allowed insulation temperature at the outer wall is 50 c. Input requirements include the pipe size operating. It is typically used in process piping and chiller plants and performs best in applications below 50 f.

Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k. 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.

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

This very rigid insulation offers the lowest heat flow rate of our pipe insulation and restricts absorption of water air and gas. 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. This calculator has options for 3 different wall heights. The amount of coverage of one bundle of batt s differs by manufacturer.

The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow. In many times pipe insulation additionally minimizes the effect of the temperature of the pipe at the instant environment. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. The pipe calculator estimates the heat flows through horizontal steel piping.

Estimate the amount of insulation needed for a wall.
