Non-destructive tests represent, in addition to destructive mechanical tests, the most important elements of quality assurance for steel tubes.

Please first verify your email before subscribing to alerts. This standard is not included in any packages. These operations shall be repeated for each segment coil. Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness.

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.

100893-1 specified wall thickness exceeding 10 mm, the wall thickness of the reference tubes may be greater than the specified wall thickness of the pipe being inspected, provided the notch depth is calculated on the specified wall thickness of the pipe being inspected. For this reason, the technique detects predominantly 1093-1 imperfections having a minimum length dependant on the circumferential dimension of the transducer.

It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux een method.

You may experience issues viewing this site in Internet Explorer 9, 10 or In addition to the three standardized methods, dye penetration testing eh Part 4 and the magnetic particle inspection see Part 5which are used to detect surface imperfections shall be mentioned. It is the constant aim of BSI to improve the quality of our products and serv- ices. 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.

The signal response from internal surface imperfections can thus be smaller than that from an external imperfection of the same size.

It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm, when testing with eddy current, and greater than 10 mm when testing with flux leakage method. The minimum length of the longitudinal imperfection which is detectable is principally determined by the search coil arrangement and by the rate of change of section along the length of the imperfection.

Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness 1 Scope This part of ISO specifies requirements for automated electromagnetic testing of seamless and welded steel tubes, with the exception of submerged arc-welded SAW tubes, for verification of hydraulic leaktightness.

This publication does not purport to include all the necessary provisions of a contract.
