It is the responsibility of the user of this standard to establish appro1 This practice is under the jurisdiction ast, ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E 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.

Any of the apparatus types listed in Note 1 4. For material with an outside diameterto-thickness ratio less than 7, a lower refracted angle or corresponding parameters for non-contact techniques must be used to ensure intersection with the inside surface. NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser.

These procedures have been used successfully for smaller sizes, however, and may be specified upon contractural agreement between the using parties. 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. Link to Active This link will always route to the current Active asfm of the standard. At the option e123 the xstm agency, shallower notches may be used to provide d213 more stringent examination.

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 e231 responses when examining small-diameter, thin-wall tubes.

This requirement may be stated as: Current edition approved June 1, The fractional percentage change in notch A2. 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. Rust inhibitors, softeners, and wetting agents may be added to the couplant.

In some instances, such as? NOTE 6—The amplitude of indications obtained from reference notches may not be linearly proportional to notch depth.

ASTM E – 14E1 – Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing

Record the peak amplitude of the signal from the inner surface notch. Details of the procedures used to establish and apply the distance-amplitude correction DAC curve shall be established by the using party or parties.

Measurements may be made by optical, replicating, or other agreed upon techniques. 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.

Restandardize and reexamine the material if necessary, in accordance with the following procedures, unless otherwise speci? The practice or standard used and its applicable revision shall be identi? The reference pipe or tube shall be free of discontinuities or other conditions producing indications that can interfere with detection of the reference notches. These procedures have been successful with smaller sizes. The SI equivalents are in parentheses and may be approximate.

NOTE 10—Some traversing mechanisms do not allow examination of pipe or tube ends. Note— Alternatively, set-up on the inner surface notch may be performed before set-up on the outer surface notch, as described in step h above. NOTE 12—Care should be exercised to ensure that reworking a pipe or tube does not change its acceptability with respect to other requirements of the material speci?

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

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.

If such a signal does not exist, make more frequent equipment standardization checks. When examination of heavy-wall pipes and tubes is required the focal length, refraction angle and included beam angle of focused search units shall be suitable for complete through-wall coverage See 5.

ASTM E Standard for Ultrasonic Testing of Metal Pipe Tube This practice covers a procedure for detecting discon- tinuities in metal pipe and steel tubing during a volumetric exami- nation using ultrasonic methods.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Run the reference standard with random initial translational and angular orientation through the examination station at full speed and scan pitch and observe, during multiple runs of the standard, the stability of the gated alarm signals from all notches in the reference standard on a strip-chart recorder or other means for observing signal amplitude stability or alarm function.

A method for achieving the required conditions is described below.

The incident and refracted beams in these cases are pictured as being generated by a cylindrically focused immersion search unit. These may be specified upon contractual agreement between the using parties. The response from the inner and outer surface notches should be as nearly equal as possible. This may be in the form of a strip chart recording or computerized data of the ultrasonic instrument output during the examination.

Specific techniques of the ultrasonic method to which this practice applies include pulse-reflection techniques, both contact and non-contact for example, as described in Guide Eand angle beam immersion techniques. Excessive surface roughness or scratches can produce signals that interfere with the examination.

NOTE 5—For as-rolled or scaly pipe or tube surfaces, it may be necessary to modify For thick-wall tubes a lower refraction angle may be required for examination of the entire thickness 5. 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. 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.

These may be speci? This standard does not purport to address all of the safety concerns, if any, associated with its use. 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?

This does not ensure detection of midwall discontinuities See Reference 5. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

An independent channel or channels of instrumentation shall be employed to individually monitor the responses from the e13 and, when required, transverse oriented search units. Then the following steps shall be taken, depending upon the nature of the failure.
