NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser. These procedures have been successful with smaller sizes.
ASTM E213 Standard for Ultrasonic Testing of Metal Pipe Tube
ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned e2113 this standard. NOTE 5—For as-rolled or scaly pipe or tube surfaces, it may be necessary to modify NOTE 8—Identical conditions include all instrument settings, mechanical motions, search unit position and alignment relative atm the pipe or tube, liquid couplant, and any other factors that affect the performance of the examination. The immersion method is almost always required for examining tubes for these uses.
This signal may be observed, but not gated, as a supplement to the required checking of the reference standard to provide increased assurance that the equipment is functioning properly.
In some instances, such as? This depends upon the intercepting beam width to notch length.
ASTM E – 14E1 – Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing
Certain combinations of search unit size, frequency, thin wall thicknesses, and small diameters could cause generation d213 unwanted sound waves that may produce erroneous test results. The methods used for cleaning and preparing the surfaces for ultrasonic examination shall not be detrimental to the base metal or the surface? On large diameter or heavy wall pipe and tubing, if the inner and outer surface notch amplitude cannot be made equal because of material soundpath distance and inside diameter curvature, a separate rejection level may be established for the inner and outer surface notches.
NOTE 9—If a requirement exists for both longitudinal and transverse astmm the sstm three options are available: When required, transverse outer surface and inner surface reference notches are typically placed in the same manner near the opposite end of the reference standard from the longitudinal notches.
Standard ASTM E Standard for Ultrasonic Testing of Metal Pipe Tube This practice covers a procedure for detecting discon- tinuities in astj pipe and steel tubing during a volumetric exami- nation using ultrasonic methods.
Details of the procedures used to establish and apply the distance-amplitude correction DAC curve shall be established by the using party or parties. Some differences in this procedure are required, as described below, depending upon whether the contact or immersion technique is employed.

Rust inhibitors, softeners, and wetting agents may be added to the couplant. Alternatively, the using party or parties may specify speci? These procedures are intended to ensure that proper beam angles satm 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. 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 thicknessand to avoid spurious signal responses when examining small-diameter, thin-wall tubes.
The values stated in inch-pound units are to be regarded as w213. This standard does not purport to address all of the safety concerns, if any, associated with its use. If indexed axial scanning is used, the same stability veri?

Basis of Application 6. A number in parentheses indicates the year of last reapproval. Alternatively, the search unit may be angulated in asfm plane perpendicular to the tube axis to produce the incidence angle. Direct the search unit beam in one circumferential direction. Excessive surface roughness or scratches can produce signals that interfere with the examination. The relative response from the inner and outer surface notches shall be as nearly equal as possible by selection of the pair of adjacent inner surface and outer surface notch signal nodes are observed.
Rotate the tube without translation that is, without motion along its longitudinal axis and observe on the instrument display screen the motion of the notch signal away from any residual interface signal.

A higher minimum value is desirable and may be speci? This may be in the form of a strip chart recording or computerized data of the ultrasonic instrument output xstm the examination.
These procedures have been successful with smaller sizes. For very large-diameter material where this requirement is found to be impractical search units of aetm focal lengths or unfocused units may be used. The instrument pulse repetition rate shall be capable of being adjusted to a sufficiently high value to ensure notch detection at the scanning rate employed.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM asm the above address or at phonefaxor service astm. Record the peak amplitude of the signal from the inner surface notch. For small tubes, support mechanisms must be used in the examination station to prevent any transverse motion with respect to the search unit beam during scanning.
This may be achieved in the immersion method by parallel offsetting the beam centerline from a perpendicular to a tangent of the surface by a distance equal to 1? It shall contain recordings of all standardizations and standardization checks and should be annotated to provide a positive correlation between examination wstm for each reject pipe or tube and the corresponding pipe or tube. It is the responsibility of the user of this standard to establish appropriate safety and health practices axtm determine the applicability of regulatory limitations prior to use.
