As the voice of the U. Need more than one copy? Square or rectangular tubes with a maximum dimension across the diagonal of mm may also be tested using this technique with adequately shaped coils.

For this 1093-1, the 108931 detects predominantly transverse imperfections having a minimum length dependant on the circumferential dimension of the transducer.

NOTE The magnetic transducers can take different forms, for example absolute and differential, depending on the equipment used and other factors. Ultrasonic testing is the usual test method for all tube thicknesses and tube diameters; it is the preferred test method especially for thick-walled tubes.

When using a single reference hole in the sample test pipe, the sample test pipe shall be passed through the inspection equipment with the reference hole, on successive runs positioned as requested in 6. Accept and continue Learn more about the cookies we use and how to change your settings.

There is no restriction on the maximum outside diameter using these techniques. Increasedtest speeds can be achieved with the electromagnetic methods eddy current method and magnetic leakage-flux method where the eddy current method is limited to pipes with smaller diameters and the magnetic leakage-flux method to ferromagnetic pipes. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

The surfaces shall be sufficiently free of foreign matter which can interfere with the validity of the test. NOTE 2 In special cases, for example testing hot tubes or using equipment contained within a continuous tube mill, a modified calibration or calibration checking procedure can be used, by agreement.

By agreement between the purchaser and manufacturer, the suspect area may be retested by other non-destructive techniques and test methods to agreed acceptance levels.

You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. The capacity of the test equipment to detect subsurface or internal surface imperfections is determined by various factors, but predominantly by the thickness of the tube under test and the eddy current excitation frequency.

It is incorporated by Royal Charter. When using this technique on ferromagnetic steel, the products 1089-1 inspection shall be magnetically saturated inserting them into an external strong magnetic field. After checking that the remaining thickness is within tolerance, the tube shall be tested as previously specified. Radiographic testing of weld seams with X-rays has been established for testing safety-relevant tubes for example, in nuclear technology.

The signal rn from internal surface imperfections can thus be smaller than that from an external imperfection of the same size. For dated references, only the edition cited applies. You may delete a document from your Alert Profile at any time.

The work of preparing International Standards is normally carried out through ISO technical committees.

This part of ISO can also be applicable to the testing of hollow sections. Figure 5 — Simplified diagram of magnetic flux leakage technique for the detection of transverse imperfections 6 Reference tube 6. For this reason, this technique detects longitudinal imperfections with a minimum length dependent on the width of the test coil and the inspection helical pitch.

These signals shall be used to activate their respective trigger alarm of the equipment. It is recognized that longitudinal imperfections are not normally detectable unless they have 100893-1 significant transverse component oblique.

The signal response from a subsurface or internal surface imperfection is thus smaller than that from an external surface imperfection of the same size. It is the constant aim of BSI to improve the quality of our 10983-1 and serv- ices. A list of organizations represented on this committee can be obtained on request to its secretary.

These operations shall be repeated for each segment coil. Amendments issued since publication Date Text affected www.
