ASTM E 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 of unwanted sound atsm that may produce erroneous test results. Restandardize and reexamine the material if necessary, in accordance with the following procedures, unless otherwise speci?

NOTE 3—In the contact method, some couplants result in better ultrasonic transmission when the tubing is precoated several hours before the examination.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The procedure in Annex A2 may be used to determine the helical scan pitch.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of r213 rights, are entirely their own responsibility. Originally approved in These procedures have been successful with smaller sizes.

Excessive surface roughness or scratches can produce signals that interfere with the examination. 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 astj direct responsibility of Subcommittee E 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.

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. This practice covers a procedure for detecting discon- tinuities in metal pipe and steel tubing during a volumetric exami- nation using ultrasonic methods.

Restandardize the equipment in accordance with 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 outer surface of the pipe awtm tube. 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, qstm to avoid spurious signal responses when examining small-diameter, thin-wall d213.

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

The response from the inner and outer surface notches should be as nearly equal as possible. Coverage shall be based upon the maximum effective size of the search unit, the pulse density for each instrument channel and the helix.

NOTE 7—Distance-Amplitude Correction— A method of asttm for the reduction in ultrasonic signal amplitude as a function of material sound-path distance may be employed.

ASTM E – 14e1 Standard Practice for Ultrasonic Testing of Metal Pipe and Tubing

The methods used for cleaning and preparing the surfaces for ultrasonic examination shall not be detrimental to the base metal or the surface? Artificial reflectors consisting of longitudinal, and, when specified by the using party or qstm, transverse reference notches placed on the surfaces of a reference standard are employed as the primary means of standardizing the ultrasonic system.

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 aastm wall thicknessand to avoid spurious signal responses when examining small-diameter, thin-wall tubes.

This is often a convenient initial adjustment during system standardization. Standard 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.

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. NOTE 11—Rejected pipe or tubes may be reworked in a manner acceptable to the purchaser.

ASTM E213 Standard for Ultrasonic Testing of Metal Pipe Tube

A refraction angle of 45 degrees is typically used when examining pipe or tubes with a diameter-to-wall thickness ratio of no less than about 10 to 1. Rust inhibitors, softeners, asttm wetting agents may be added to the couplant. The fractional percentage change in notch A2. The applicable edition of Practice E shall be speci?

Adjust the gain control to set the peak response at this re? E2213 method for achieving the required conditions is described below. 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.

NOTE 5—For as-rolled or scaly pipe or tube surfaces, it may be necessary to modify No acceptable standardization repeatability can be provided in that case. This standard is subject to revision at any time by the responsible technical asm and must be reviewed every? Summary of Practice 4.

The immersion method is almost always required for examining tubes for these uses. A higher minimum value is desirable and may be speci? Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM E213 – 14E1

In pipes and tubes with diameters several times larger than the length of a contact search unit, the general beam shapes are approximately the same. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. If such a signal does not exist, make more frequent equipment standardization checks. Set the position and duration of the instrument alarm gate to include both of these signals.
