Claims

[Scope of utility model registration request]

In the seal ring for ultrasonic flaw detection that is attached to both sides of the rotating tank that holds the probe group and seals the couplant, there is a hole in the center of the seal ring that is aligned with the passage hole through which the cylindrical material to be inspected passes. The seal ring has a plurality of elliptical holes on the circumference around the passage hole, and has a substantially L-shaped cross section in the longitudinal direction of the elliptical hole. A first seal ring and a second seal ring each have a protrusion in a part and a notch having the same shape as the protrusion, and a first seal ring and a second seal ring are provided in the spring storage portion, respectively.
1. A seal ring for ultrasonic flaw detection, comprising a ring spring forming a pair of double seal rings in which the seal rings are arranged in opposite directions and pressed against each other.
