Calculation of Insulation Material Weight

Insulation Area (Ia)

= 

Pie() x (Pipe OD + 2 x Th) x RMT.

Where:

Pipe OD = Outer diameter of pipe (m)

Th = Insulation thickness (m)

RMT = Insulation running meter (m)

For calculation of RMT, please Insulation Material Calculation.

Volume of insulation (Iv) = Ia x Th

Mass of insulation = Volume of insulation x insulation density.

 

For Example:

Insulation thickness is 50mm, pipe size 10” & pipe length is 100m. insulation density is 128 Kg/Cu. M.

Insulation Area (Ia) = pie() x ((273 + 2 x 50)/1000) x 100

10” pipe OD is 273 & 100m is RMT.

Ia = 117.18 m2.

Volume of insulation (Iv) = 117.18 x (50/1000)

Iv = 5.859 m3.

Mass of Insulation = Volume of insulation x insulation density.

                                = 5.859 x 128

                                = 749.952 Kg or

                                = 750 Kg.
