A device for monitoring the manufacturing status of a seamless pipe, capable of quickly correcting manufacturing conditions during operation of a seamless pipe manufacturing facility. The device (20) for monitoring the manufacturing status of a seamless pipe has an ultrasonic wall thickness meter (4) installed on the outlet side of a piercing mill (10), which manufactures a pipe (S) by subjecting a billet (B) to a rolling and piercing process, and measuring the wall thickness of the pipe (S) manufactured by the piercing mill (10), a temperature meter (5) installed on the outlet side of the piercing mill (10) and measuring the temperature of the surface of the pipe (S) manufactured by the piercing mill (10), and calculation and display means (6) for displaying the wall thickness distribution in the circumferential direction of the pipe (S) and the surface temperature distribution in the circumferential direction of the pipe (S), with the display based on the wall thickness of the pipe (S) measured by the ultrasonic wall thickness gauge (4) and on the surface temperature of the pipe (S) measured with the temperature meter (5). |
