This practice covers a procedure for detecting discon-
tinuities in metal pipe and steel tubing during a volumetric exami-
nation using ultrasonic methods. Specific techniques of the
ultrasonic testing method to which this practice applies include
pulse-reflection techniques, both contact and non-contact (for
example, as described in Guide E 1774), and angle beam
immersion techniques.
Artificial reflectors consisting of longi-
tudinal, and, when specified by the using party or parties,
transverse reference notches placed on the surface of a
reference standard are employed as the primary means of
standardizing the ultrasonic system.
This practice is intended for use with tubular products
having outside diameters approximately 1⁄2 in. (12.7 mm) and
larger, provided that the examination parameters comply with
and satisfy the requirements of Section 12. These procedures
have been successful with smaller sizes.
These may be speci-
fied upon contractual agreement between the using parties.
These procedures are intended to ensure that proper beam
angles and beam shapes are used to provide full volume
coverage of pipes and tubes, including those with low ratios of
outside diameter to wall thickness, and to avoid spurious
signal responses when examining small-diameter, thin-wall
tubes.
The procedure in Annex A1 is applicable to pipe and
tubing used in nuclear and other special and safety applica-
tions. The procedure inAnnexA2 may be used to determine the
helical scan pitch.
This practice does not establish acceptance criteria; they
must be specified by the using party or parties.
The values stated in inch-pound units are to be regarded
as standard. The SI equivalents are in parentheses and may be
approximate.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
