UW-11 RADIOGRAPHIC AND ULTRASONIC
EXAMINATION
(7) ultrasonic examination in accordance with
UW-53 may be substituted for radiography for the final
closure seam of a pressure vessel if the construction of
the vessel does not permit interpretable radiographs in
accordance with Code requirements. The absence of suitable
radiographic equipment shall not be justification for
such substitution.
