Product Code : EL-HTTLP-7369
Jlab Export is a leading Heat Transfer Through Lagged Pipe Manufacturer,and suppliers in India
Heat Transfer Through Lagged Pipe (code EL-HTTLP-7369) is a heat transfer lab set-up for measuring the thermal conductivity of pipe lagging from the heat that flows radially out through it, specified with a G.I. pipe of 25 mm diameter and 1000 mm length and a capacity of 5 kW. JLab builds each lagged pipe set-up in Ambala, India, in the different specifications buyers ask for.

Radial Conduction Through the Lagging
Heat leaving the pipe crosses the lagging along the radius, so the area it passes through grows with distance from the centre. For a lagging layer with inner radius r1, outer radius r2 and length L, the conduction resistance is ln(r2/r1)/(2πkL), and at steady state the heat flow is Q = 2πkL(T1 − T2)/ln(r2/r1), where T1 and T2 are the temperatures at the inner and outer surfaces of the lagging. With Q and the two surface temperatures known, the same relation is solved for the thermal conductivity k.
Because the resistance depends on ln(r2/r1) rather than on the thickness alone, doubling the lagging thickness does not halve the heat loss. That is where a lagged pipe parts company with a flat wall, in which each layer adds a resistance of thickness/(kA).
Other Conduction Rigs: Pipe, Wall and Spheres
- Lagged Pipe Apparatus — three concentric G.I. pipes with two lagging materials and a cartridge heater.
- Heat Transfer Through Composite Wall — conduction through a composite wall of MS, Bakelite and wood specimens.
- Thermal Conductivity of Insulating Powder — radial conduction through powder held between two concentric copper spheres.
The set-up belongs to the Heat Transfer Through Lagged Pipe category of Heat Transfer Lab Equipment, part of the Engineering Lab Equipment range.
