METHOD FOR DETERMINING VALUE OF DEPOSITS ON INNER SURFACE OF PIPELINE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2012 - IPC G01B21/02 

FIELD: machine building.

SUBSTANCE: pulse heat source with action time of where R - piping radius, d - wall thickness, a -temperature conductivity is installed on pulse heat source piping according to the method for determining the thickness of deposits on inner surface of piping, and temperature change is determined at the distance l=(2.5-3.5)d from the heating source. The device for determining the thickness of deposits on inner surface of piping is equipped with generator of current radio pulses, amplifier, analogue-to-digital converter, computing device, indicator of deposit thickness and indicator of deposit heat conductivity; at that, output of current radio pulse generator is connected to induction coil; amplifier input is connected to temperature sensor output; amplifier output is connected to input of analogue-to-digital converter; output of analogue-to-digital converter is connected to input of computing device; outputs of computing device are connected to indicators.

EFFECT: possibility of monitoring the deposits of small thickness and possibility of monitoring the pipes during performance of preventive actions when the process is stopped and pipes are dehydrated.
