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.

The means of introducing magnetic flux in a direction parallel to the major axis of the tube can be achieved by methods other than that shown in this figure. NOTE Electromagnetic inspection using magnetic flux leakage method is not applicable to austenitic stainless steel tubes. NOTE The magnetic transducers can take different forms, for example absolute and differential, depending on the equipment used and other factors.

Standards Subsctiption may be the perfect solution. The faster, easier way to work with standards. 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.

For this reason, this technique detects longitudinal imperfections with a minimum length dependent on the width of the test coil and the 10983-1 helical pitch. If the document is revised or amended, you will be notified by email. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

The operating authorization issued by the employer shall be according to a written procedure. Users are responsible for its correct application. It presents the UK view on standards in Europe and at the international level. Users of British Stan- dards should make sure that they possess the latest amendments or editions. The same equipment settings, for example frequency, sensitivity, phase discrimination, filtering and magnetic saturation, shall be employed.


BS EN ISO 10893-1:2011

Radiographic testing of weld seams with X-rays has been established for testing safety-relevant tubes for example, in nuclear technology.

A list of organizations represented on this committee can be obtained on request to its secretary. The higher the excitation frequency, the lower the penetration and conversely, the lower the excitation frequency, the higher the penetration. This standard is also available to be included in Standards Subscriptions.

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. Amendments issued since publication Date Text affected www.


The manufacturer shall demonstrate, on request, the effectiveness of the adopted solution. Automated full peripheral ultrasonic thickness testing of seamless and welded except submerged arc-welded steel tubes www.

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.

Add to Alert PDF. The sides shall be nominally parallel and the bottom shall be nominally square to the sides. Non-destructive tests represent, in addition to destructive mechanical tests, the most important elements of quality assurance for steel tubes. These signals shall be used to activate their respective trigger alarm of the equipment. You may find similar items within these categories by selecting from the choices below:.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, dn the latest by Octoberand conflicting national standards shall be withdrawn at the latest by October ISO consists of the following parts, under the general title Non-destructive testing of steel tubes: For undated references, the latest edition of the referenced document including any amendments applies.
