1.1 Purpose:
This specification covers procedures for ultrasonic inspection of thin wall metal tubing of titanium,
titanium alloy, and corrosion and heat resistant steels and alloys having nominal OD over
0.1875 inch (4.762 mm) with OD to wall thickness ratio of 8 or greater and wall thickness
variation not exceeding ±10% of nominal.
1.2 Application:
This process has been used typically for locating internal defects, such as cracks, voids, seams,
and other discontinuities, which may or may not be exposed to the surface, but usage is not
limited to such applications.strRefField
