Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of three concentric pipes, at the axis of which a cartridge heater is positioned. Two types of lagging materials are filled up, one between innermost and middle pipe and other between middle and outermost pipe. Temperature across the lagging material i.e. temperature of pipe walls for radial outward heat flow are measured by the thermocouples. The heater can be supplied with different heat inputs with the help of dimmer stat so that characteristics of lagged pipe can be studied at different heat flow rates.
