The electric resistance technique was taken up as a corrosion monitor method of the equipment piping. The corrosion test on the hot water piping was done by using the electric resistance technique with the loop circulation device. The probe of the flash mount type of the electric resistance technique corrosion meter along in the inside of piping. The tap water of about 50℃ was passed for one year at flow velocity 0.6m/s and the corrosion rate was measured. The carbon steel pipe was built into the experimental apparatus, the corrosion rate was measured by the weight loss in weight method, and it compared it with the corrosion rate by the electric resistance technique. As a result, the corrosion rate of both agreed almost, and was high the approximation until about especially six months.
