Tubular member flaw detection
First Claim
1. A method for ultrasonically inspecting a tubular member, the tubular member having a first surface and a second surface, the first surface spaced apart from the second surface by a thickness of the tubular member, and two spaced-apart ends including a first end and a second end of the tubular member, the method comprisingtransmitting sonic beams to the tubular member with transducer apparatus such that sonic beams are reflected from the first surface of the tubular member and from the second surface of the tubular member, the transducer apparatus controlled by control apparatus, while continuing to inspect the first surface of the tubular member for first surface defects, moving the transducer apparatus adjacent sensing apparatus which signals the control apparatus to cease processing of transducer apparatus signals related to inspection of the second surface, and, the transducer apparatus continuing to transmit sonic beams for the inspection of the first surface of the tubular member, and completing inspection of substantially all of the second surface of the tubular member for second surface defects while continuing to inspect the first surface of the tubular member for first surface defects.

Abstract
A method for ultrasonically inspecting a tubular member which has a first surface spaced-apart from a second surface by a thickness of the tubular member, and two spaced-apart ends the method including transmitting sonic beams to the tubular member with transducer apparatus which are reflected from the first surface and from the second surface, the transducer apparatus controlled by control apparatus, while to inspect the first surface for first surface defects, moving the transducer apparatus adjacent sensing apparatus which signals the control apparatus to cease processing of signals related to inspection of the second surface, and, the transducer apparatus continuing to transmit sonic beams for the inspection of the first surface, and completing inspection of substantially all of the second surface for second surface defects while continuing to inspect the first surface.

24. An ultrasonic inspection device useful for inspecting a tubular member comprising
transducer apparatus for transmitting sonic beams and for receiving reflected beams thereof from inner and outer surfaces of the tubular member, and from defects of the tubular member, the reflected beams including beams reflected from an outer surface of the tubular member and from an inner surface of the tubular member, and from a defect of the tubular member, and means for differentiating the reflected beams, means for producing signals corresponding to information about the reflected beams, including a defect signal having information about the defect, and an end signal from proximity switch apparatus positioned with respect to an end of the tubular member, and means for continuing inspection of one surface of the tubular member following cessation of inspection of the other surface of the tubular member.
