In some instances, such as? Alternatively, the using party or parties may specify speci? 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 diameterto-wall thickness, and to avoid spurious signal responses when examining small-diameter, thin-wall tubes. Alternatively, the search unit may be angulated in a plane perpendicular to the tube axis to produce the incidence angle. These procedures have been successful with smaller sizes.

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

If, upon ultrasonic reexamination of the reworked pipe or tube, no rejectable indications are detected, the material should be considered as having passed the ultrasonic examination.

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. Basis of Application 6. Originally approved in This is often a convenient initial adjustment during system standardization.

If you feel that your comments have not received a fair hearing you should make your views w213 to the ASTM Committee on Standards, at the address shown below.

The procedure in Annex A2 may be used to determine the helical scan pitch. Rust inhibitors, softeners, and wetting agents may be added to the couplant. In cases where the type ast examination, material dimensions or other properties make the use of spherically or?

These may be specified upon contractual agreement between the using parties. Excessive surface roughness or scratches can produce signals that interfere with the examination. This standard does not purport to address all of the safety concerns, if any, associated with its use. The relative responses from both the inner and outer surface notches should be as nearly equal as possible and practical.

The SI equivalents are e2213 parentheses and may be approximate. Some differences in this procedure are required, as described below, depending upon whether the contact or immersion technique is employed.

At the option of the testing agency, shallower notches may be used to provide a more stringent examination. The awtm pulse repetition rate shall be capable of being adjusted to a sufficiently high value to ensure notch detection at the scanning rate employed.

Record all search unit position settings, instrument control settings and standardization signal levels on an examination record sheet.

The fractional percentage change in notch A2. The supplier shall maintain a report of the examination on?

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 the primary means of standardizing the ultrasonic system. Standardization of Apparatus Summary of Practice 4.

Artificial discontinuities consisting of longitudinal reference notches are employed as the primary means of calibrating the ultrasonic system. The procedure inAnnexA2 may be used to determine the helical scan pitch. 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.

These procedures have been successful with smaller sizes. NOTE 6—The amplitude of indications obtained from reference notches may not be linearly aztm to notch depth. These procedures have been successful with smaller sizes. The SI equivalents are in parentheses and may be approximate. 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 Largest Open Access Portal of Nondestructive Testing (NDT)

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.

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. The actual length of the worst case interception may be represented by:
