Pipe insulation thickness calculation xls.

Calculation for pressure drop. Thickness is a critical factor in the success or failure of an insulation system. Jump to page. 500 m required inputs valid of turbulent flo average heat capacity of fluid 2 570 kj kg k fluid viscosity 5 200 cp the chemical engineers resource page thermal cond of fluid 0 600 w m k thermal cond of pipe 30 000 w m k pipe r1 0 020 m r2 0 026 m r3 0 526 m mass flow 350000 000 kg h ax pipe 0 001 m 2 r1 heat transfer coefficient outside pipe 50 000 w m 2 k.

D s is the outside diameter of the insulated pipe i e. In many times pipe insulation additionally minimizes the effect of the temperature of the pipe at the instant environment. Insulation thickness 77 7 mm. Extra margin must be taken on insulation thickness as sometimes conducting heat transfer through insulation may become higher than convective heat transfer due to air on outside wall of insulation.

The basic model of insulation on a pipe is shown in figure the selected material has to satisfy all requirements but the economic thickness of pipe insulation varies according to type because of the final thickness of insulation which meets the management s criteria is acceptable and represents the economic thickness of insulation this calculation fetch this document. 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. Insulation thickness calculation of pipe. Hence insulation thickness ri rp 0 2302 0 1524 0 0777.

The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c. But without the right tool for the job determining the appropriate fiber glass or mineral wool insulation thickness for a particular application can be challenging. The heat loss from steam per meter of pipe length has to be. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.

In general there are no insulation thickness requirements for residential heating pipes but we find that a minimum of 1 thickness is cost efficient in most scenarios. You are on page 1 of 3. Naima s free 3e plus software program makes it easy to calculate. In almost every scenario involving a heating pipe replacing 1 2 thickness pipe insulation with 1 thickness pipe insulation reduces the loss of heat transmission in half.
