Abstract
In the on-line measurement of the wall thickness of a steel pipe, use is made of a rotary-type magnetic-ultrasonic wall thickness measuring apparatus capable of measuring the wall thickness of the steel pipe along the whole periphery circumferentially whereby measured data signals from the wall thickness measuring apparatus are reduced for each of a plurality of inspection blocks comprising small section established in a longitudinal direction of the steel pipe, and the resulting measured data groups are subjected to a pass-fail discrimination in according with predetermined criteria thereby making possible the control of such qualities as the wall thickness, thickness deviation rate and average inner diameter for each product.
