Abstract
For ultrasonic measurement of pipe seam peaking, optionally with simultaneous ultrasonic wall thickness measurement using ultrasonic probes mounted on sensor holders on a sensor mount, it is proposed to use a sensor mount with sensor holders mounted on movable skids, which are pressed outward by spring elements and bear against the internal pipe surface, and skids having a large skid breadth greater than the seam peak breadth measured in the pipe's circumferential direction in the region of a measured seam peak, and sensor holders equipped with sensors only in a measuring region situated half way between two skid contact surfaces, wherein the measuring region breadth is less or equal to half of the skid breadth such that the stand off deviation of the sensors resulting in the seam peak region remains below a threshold value.
