Alternatively, the using party or parties may specify speci? The reference pipe or tube shall be free of discontinuities or other conditions producing indications that can interfere with detection of the reference astn.

For many materials a satisfactory initial offset distance is 1? Although not mandatory, this practice enables all notches to be placed far enough from the ends to insure good support of the material end nearest the search unit s during set-up, and the inner surface notches to be near ends to facilitate insertion of the fabrication and awtm

The SI equivalents are in parentheses and may be approximate. The incident and refracted beams in these cases are pictured as being generated by a cylindrically focused immersion search unit. For small tubes, aastm mechanisms must be used in the examination station to prevent any transverse motion with respect to the search unit beam during scanning. An independent channel or channels of instrumentation shall be employed to individually monitor the responses from the longitudinal and, when required, transverse oriented search units.

The SI equivalents are in parentheses and may be approximate.

On 2e13 or heavywall pipe and tubing, d213 the inner and outer surface notch signal amplitudes cannot be equalized because of material sound path distance and inside diameter curvature, a separate rejection level may be established for the inner and outer surface notches, or, in this case, DAC may be used to balance the signal amplitudes from the outer surface and inner surface notches.

Axial scanning with circumferential indexing may be used to provide equivalent coverage. Restandardize the equipment in accordance with The practice or standard used and its applicable revision shall be identi?

Active view current version of standard. For thick-wall tubes a lower refraction angle may be required for examination of the entire thickness 5. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.

Measurements may be made by optical, replicating, or other agreed upon techniques. Any of the apparatus aetm listed in Note 1 4.

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? The SI equivalents are in parentheses and may be approximate. Basis of Application 6. NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser. Interpretation of Results Annex A2 describes how maximum allowable pitch for stable detection may be determined from the length of the longitudinal reference notches adtm the minimum beam length of the search units.

Make ashm checks prior to any examination run, prior to equipment shutdown after an examination run, and at least every four hours during continuous equipment operation.

The procedure in Annex A2 may be used to determine the helical scan pitch. These may be specified upon contractual agreement between the using parties. In some instances, such as? These may be speci? 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.

When this condition exists, clearly indicate the extent of this effect, per tube, in the examination report. Originally approved in This practice covers a procedure for detecting discon- tinuities in asstm pipe and steel tubing during a volumetric exami- nation using ultrasonic methods.

Direct the search unit beam in one circumferential direction. 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 atsm low ratios of outside diameter-to-wall thickness, and to ee213 spurious signal responses when examining small-diameter, thin-wall tubes.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. These procedures have been used successfully for smaller sizes, however, and may be specified upon contractural agreement between the using parties.

It shall contain recordings of all standardizations and standardization checks and should be annotated to provide a positive correlation between examination record for each reject pipe or tube and the corresponding pipe or tube. Make these checks prior to any examination run, prior to equipment shutdown after an examination run, and at least every hour during continuous equipment operation. It is the responsibility of the user of this standard to establish appro1 This practice is under the jurisdiction of ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E 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.

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. NOTE 1—The immersion method may include tanks, wheel search units, or systems that use streams or columns of liquid to couple the ultrasonic energy from the search unit to the material.

This signal may be observed, but astj gated, as a supplement to the required checking of the reference standard to provide increased assurance that the equipment is functioning properly.

This depends upon the intercepting beam width to notch length. 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 number in parentheses indicates the year of last reapproval. Record all search unit position settings, instrument control settings and standardization signal levels on an examination record sheet.

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. The report shall include at least the following information:
