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. They are widely used, often during production, for quality assurance.
Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness. For details of these and other benefits contact Membership Ad- ministration.
Non-destructive tests are primarily used on pressure-retaining pipes for chemical, petrochemical and power station industries. It is recognized that longitudinal imperfections are not 18093-1 detectable unless they have a significant transverse component oblique.

NOTE The pancake coils in a and b can have different forms, e. For this reason, the technique 110893-1 predominantly transverse imperfections having a minimum length dependant on the circumferential dimension of the transducer. After checking 18093-1 the remaining thickness is within tolerance, the tube shall be tested as previously specified.
Automated electromagnetic testing of seamless and welded except submerged arc-welded steel tubes for the verification of hydraulic leaktightness Status: The work of preparing International Standards is normally carried out through ISO technical committees.
It supersedes BS EN Ne to Checkout Continue Shopping. 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.

ISO consists of the following parts, under the general title Non-destructive testing of steel tubes: BSI also holds the copyright, in the UK, of the publications of the international standardization bodies. ISO ; b statement of conformity; c any deviation, by agreement or otherwise, from the procedures specified; d product designation by steel grade and size; e type and details of inspection technique s ; f equipment calibration method used; g description of the reference standard acceptance level; h date of test; i operator identification.
It is incorporated by Royal Charter. This part of ISO can also be applicable to the testing of hollow sections.
Wn shall not be held responsible for identifying any or all such patent rights. This does not preclude the free use, in the course of implementing the standard of necessary details such as symbols, and size, type or grade designations. The same equipment settings, for example frequency, sensitivity, 1893-1 discrimination, filtering and magnetic saturation, shall be employed.
In this case, the manufacturer shall demonstrate that the test sensitivity achieved using the reference hole and the equipment settings, for example signal rate filtering, is essentially equivalent to that obtained when using the reference notch.

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 leak-tightness in substitution of hydrostatic test.

For dated references, only 108993-1 edition cited applies. If the document is revised or amended, you will be notified by email. During the fIux leakage testing of tubes, the sensitivity of the test is at a maximum at the tube surface adjacent to the magnetic transducer and decreases with increasing tube thickness due to effective diminishing flux diversion from imperfections at the tube bore surface in relation to that at the external surface.
