Claims

[Scope of utility model registration request]

An outer radius measurement head that measures the outer radius of the tube to be inspected, a wall thickness measurement head that measures the wall thickness of the tube to be inspected, and a pressing cylinder that supports the outer radius measurement head so as to be movable back and forth, and also measures the wall thickness. A stand that supports the head so that it can move back and forth and swing by another pressing cylinder, an arc-shaped rail that supports the stand so that it can move along an arc centered on the center of the pipe to be inspected, and A tube wall thickness measuring device characterized by comprising an arcuate rack attached to a rail, a pinion meshed with the arcuate rack, and a pedestal drive device comprising a drive motor on a pedestal for driving the pinion.
