ASTM E – 98 Standard Practice for Ultrasonic Examination of Metal Pipe and Tubing NO_PDF
This inner surface notch signal must be well beyond the direct-in signal from the outer surface notch. No acceptable standardization repeatability can be provided in that case.
These may be specified upon contractual agreement between the using parties.
Some differences in this procedure are required, as described ast, depending upon whether the contact or immersion technique is employed. These procedures have been successful with smaller sizes. In some instances, such as? When this condition exists, clearly indicate the extent of this effect, per tube, in the examination report. The following selection and standardization procedure shall be used unless an alternative is approved by the contracting agency.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine asfm applicability of regulatory limitations prior to use. A higher minimum value is desirable and may be speci?
Certain combinations of search unit size, frequency, thin wall thicknesses, and small diameters could cause generation of unwanted sound waves that may produce erroneous test results. Restandardize and reexamine the material if necessary, in accordance with the following procedures, unless otherwise speci?
Axial scanning with circumferential indexing may be used, especially on larger material, to provide equivalent coverage. The procedure inAnnexA2 may be used to determine the helical scan pitch.
ASTM E213 – 14E1
Use the lesser of the two responses to establish the rejection level. These procedures are intended to ensure that proper refraction angles and beam shapes are used to provide full volume coverage of pipes and tubes, including those with low ratios of outside adtm thickness, and to avoid spurious signal responses when examining small-diameter, thin-wall tubes.
To prevent spurious signals or loss of sensitivity, or both, care must be taken to avoid the presence of air bubbles in the couplant. Axial scanning with circumferential indexing may be used to provide equivalent coverage. NOTE 5—For as-rolled or scaly pipe or tube surfaces, adtm may be necessary to modify A method for achieving adtm required conditions is described below. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
ASTM E – 14e1 Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing
The procedure in Annex A2 may be used to determine the helical scan pitch. This may be achieved in the immersion method by parallel offsetting r213 beam centerline from a perpendicular to a tangent of the surface by a distance equal to 1?
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. The pipe or tubing to be examined and the search unit assembly shall have a rotating translating motion relative to each other such that a helical scan path will be described on the ee213 surface of the pipe or tube.
ASTM E213 Standard for Ultrasonic Testing of Metal Pipe Tube
The response from the inner and outer surface notches should be as nearly equal as possible. If indexed axial scanning is used, the same stability veri? NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser.
It is the responsibility of the user of this standard to establish appro1 This practice is under qstm jurisdiction of ASTM Committee E07 on Nondestructive Testing and is the direct responsibility of Subcommittee E Basis of Application 6. Rust inhibitors, softeners, and wetting agents may be added to the couplant. Make these checks prior to any examination run, prior to equipment shutdown after an examination run, and at least every four hours e2113 continuous equipment operation.
This depends upon the intercepting beam width to notch length. 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. The supplier shall maintain a report of the examination on?
The relative responses from both the inner and outer surface notches should be as nearly equal as possible and practical. Artificial reflectors consisting of longitudinal, and, when specified by the using party or parties, transverse reference notches placed on the surfaces of a reference standard are employed as f213 primary means of standardizing the ultrasonic system. If transverse as well as longitudinal examination is desired, a procedure for employing transverse notches is provided.

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.
