Claims

[Scope of utility model registration request]

In a seal ring for ultrasonic flaw detection that is attached to both sides of a rotating tank that holds a group of probes and seals the couplant, there is a hole in the center of the seal ring through which the 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 a circumference centered on , and a part of the seal ring is located in the longitudinal direction of the elliptical hole so as to disturb the weight balance. It is constructed by combining a plurality of double sealings, each consisting of a first sealing ring having weight and a second sealing ring, which is the same as the first sealing ring, and is made up of a pair of coil springs that pull each other in opposite directions. Seal ring for ultrasonic flaw detection.
