Information about the changes to this standard is published in the annual (as of January 1 of the current year) reference index «National standards», and the text changes and amendments — in monthly information index «National standards». In case of revision (replacement) or cancellation of this standard a notification will be published in the monthly information index «National standards».

Introduction


International standard ISO 10893−11 cancels and replaces the technically revised ISO 9764:1989 ISO 9765:1990.

In the complex of ISO 10893 under the name «non-destructive testing of steel tubes» includes:

— part 1. Automatic electromagnetic inspection of steel seamless and welded tubes (except tubes produced by arc welding under flux) for verification of the tightness;

— part 2. Automatic inspection eddy current seamless and welded steel pipes (excluding pipes obtained by arc welding under flux) for detection of defects;

— part 3. Automatic control method of magnetic flux leakage around the entire circumference of seamless and welded pipes made of ferromagnetic steel (except tubes produced by arc welding under flux) for the detection of longitudinal and/or transverse defects;

— part 4. The control method of penetrating liquids seamless and welded steel tubes for the detection of surface defects;

— part 5. Control method of magnetic particles seamless and welded pipes made of ferromagnetic steel for detecting surface defects;

— part 6. Radiographic testing of the weld of welded steel tubes for detection of defects;

— part 7. Digital radiographic testing of the weld of welded steel tubes for detection of defects;

— part 8. Automatic ultrasonic testing of seamless and welded steel tubes for the detection of laminations;

— part 9. Automatic ultrasonic testing for the detection of laminations in the strip/sheet metal used to manufacture welded steel pipes;

— part 10. Automatic ultrasonic testing along the whole circumference of seamless and welded steel pipes (excluding pipes obtained by arc welding under flux) for the detection of longitudinal and/or transverse defects;

— part 11. Automatic ultrasonic testing of the weld of welded steel tubes for the detection of longitudinal and/or transverse defects;

— part 12. Automatic ultrasonic control of thickness around the circumference of seamless and welded steel pipes (excluding pipes obtained by arc welding under flux).

1 Scope


This standard establishes requirements for the ultrasonic method (the usual method or by using phased arrays) computer control transverse wave welds (received arc submerged arc welding, SAW) steel pipes or steel tubes obtained by electric welding (welding by the electrical resistance or electromotive, EW).

For tubes produced by arc welding under flux control is carried out for detecting defects oriented mostly in parallel and (or) by agreement, perpendicular to the weld seam.

Pipe obtained by the welding, control is carried out to detect defects, oriented mainly parallel to the weld seam. In the case of the control for the detection of longitudinal defects only, manufacturer discretion, may use lamb waves.

Detection of defects in welded joints welded pipes is possible when carrying out ultrasonic testing of the whole pipe.

This standard can also be applied to control round hollow profiles.

Note — Ultrasonic testing of seamless and welded (except received arc submerged arc welding) pipes across the surface should be carried out in accordance with ISO 10893−10.

3 Terms and definitions


This standard applies the terminology of ISO 5577 and ISO 11484 and the following terms with respective definitions:

3.1 calibration reflector (reference standard): Reflector to configure the non-destructive testing equipment (e.g. hole, notches etc.).

3.2 adjusting sample tube (reference tube): Tube or pipe used for the settings.

3.3 configuration sample (reference sample): Sample (e.g. a segment of a pipe, coil or sheet) used for configuration.

Note — the Term «sample tube» used in this standard, also includes the term «configuration model».

3.4 pipe (tube) Hollow long product, open at both ends, of any shape in cross section.

3.5 welded tube (welded tube): Pipe manufactured by forming a hollow profile from a flat product and welding adjacent edges together, and which after welding can be further processed (hot or cold) to its final dimensions.

3.6 welded tube (electric welded tube): Pipe manufactured in a continuous or discontinuous process, in which the coil is formed cold into a hollow profile, and the weld is made by heating the edges through high current or low frequency and pressing the edges together.

Note — the electric current may be supplied by direct electrode contact or via magnetic induction.

3.7 the manufacturer (manufacturer): Organization that manufactures products in accordance with the relevant standards and States the conformity of the delivered products with all applicable provisions of the relevant standard.

3.8 agreement (agreement): a Contractual relationship between the manufacturer and the customer at the time of enquiry and order.

4 General requirements

4.1 If the specification for the products or the agreement between the customer and the manufacturer do not stipulate otherwise, the ultrasonic inspection should be carried out on tubes after completion of all primary technological operations of production (rolling, heat treatment, cold and hot deformation, processing size, pre-edits, etc.).

Holodnodeformirovannyh ultrasonic inspection of pipes should be carried out after ekspedirovanie. Inspection spirally pipe, not subjected to hydraulic tests can be carried out directly in the production process.

4.2 the Pipe shall be sufficiently straight to ensure the possibility of control. The pipe surface must be free from foreign matter, which may affect the testing results.

4.3 Control should only be undertaken by trained operators, qualified in accordance with ISO 9712, ISO 11484 or equivalent documents and under the supervision of competent personnel appointed by the manufacturer (the manufacturer). In case of inspection by a third party this must be agreed between the purchaser and the manufacturer. Control by permission of the employer must be conducted in accordance with written procedure. The procedure of nondestructive testing must be coordinated by a specialist 3 level, and personally approved by the employer.

Note — the Definition of levels 1, 2 and 3 to watch in relevant international standards, e.g. ISO 9712 and ISO 11484.
