Abstract

PURPOSE: To simplify the mechanism and to enable the shipment of products with high quality, by obtaining the tube thickness data of the same cross section of pipe with non-contactness, through the adoption of ultrasonic wave measuring system with water jet nozzle method.
CONSTITUTION: The V roller tilting the roller shaft by the set angle θ to the carrying direction X-X' is located with a given distance, each roller is in synchronous drive to perform skew feed the pipe while revolution, the diameter of pipe is measured and detected (B), the carrying speed of the pipe is operated (C), the thickness of pipe is detected (D) at the surrounding eight points by measn of the water jet pulse echo system by ultrasonic waves, and marking is made for the part when the rate of deflected thickness is in excess of a permissible range. As a result, the deflection thickness rate of pipe at almost the same cross section can accurately be discriminated.
