Key Features
- Three concentric pipes mounted on a stand, with two different lagging materials between them
- Central cartridge heater provides a controlled heat source along the pipe axis
- Thermocouples attached at pipe surfaces measure intermediate temperatures
- Voltmeter and ammeter measure heater input power
- Allows calculation of the resultant thermal conductivity of the lagging materials
- Dimmerstat provides controlled variation of heater power input
Applications
The Lagged Pipe Apparatus is used in heat transfer laboratories to study radial conduction through cylindrical insulation layers, helping students determine the thermal conductivity of pipe lagging materials used to reduce heat loss in industrial piping.

Frequently Asked Questions
Q1. What does the Lagged Pipe Apparatus measure?
It measures the thermal conductivity of insulating (lagging) materials packed between three concentric pipes.
Q2. How many pipes and lagging layers are used?
Three concentric GI pipes are used, with two different lagging materials filling the spaces between them.
Q3. How is heat applied to the pipe?
A Nichrome wire cartridge heater is placed centrally along the axis of the innermost pipe.
Q4. How are intermediate temperatures measured?
Cr/Al thermocouples attached to the pipe surfaces feed a multichannel digital temperature indicator (0-300°C range).
Q5. What utilities are required to operate the apparatus?
It requires a single-phase 230V AC electric supply and a floor area of approximately 1.5m x 1m x 0.5m height.
