て一対となす超音波探傷用シールリング。 In a seal ring for ultrasonic flaw detection that is attached to both sides of a rotary tank that holds a group of probes and seals the couplant, there is a hole in the center of the seal ring through which a cylindrical material to be inspected passes, and a hole that passes through the passage hole. It has a plurality of elliptical holes and a spring holding part located on the circumference around the center, and a part of the seal ring is located in the longitudinal direction of the elliptical hole so as to disturb the weight balance. A first seal ring having a protrusion having an approximately L-shaped cross section and a second seal ring, which is the same as the first seal ring, are made into a pair by coil springs that pull each other in opposite directions. Seal ring for sonic flaw detection.
