Insulation thickness calculation of pipe. Hence insulation thickness ri rp 0 2302 0 1524 0 0777. 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. 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.

Naima s free 3e plus software program makes it easy to calculate. Calculate insulation thickness minimum value required for a pipe carrying steam at 180 0 c. The pipe diameter plus two times the insulation thickness m k is the insulation thermal conductivity w m 1 k 1 δt is the temperature difference between the insulation surface and ambient air t s t a k h s is the insulation to air heat surface heat transfer coefficient w m 2 k 1. 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.

Thickness is a critical factor in the success or failure of an insulation system. Jump to page. Search inside document. Thermal conductivity of the insulation material for the temperature range of the pipe can be taken as 0 04 w m k.

The heat loss from steam per meter of pipe length has to be. You are on page 1 of 3. In many times pipe insulation additionally minimizes the effect of the temperature of the pipe at the instant environment. 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.

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. D s is the outside diameter of the insulated pipe i e. The pipe size is 8 and the maximum allowable temperature of outer wall of insulation is 50 0 c.
