14、f national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. In

15、ternational organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with

16、the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval

17、 by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10332 was prepared by Technical Committee

19、served 1Non-destructive testing of steel tubes Automated ultrasonic testing of seamless and welded (except submerged arc-welded) steel tubes for verification of hydraulic leak-tightness 1 Scope This International Standard specifies requirements for automated ultrasonic shear-wave (generated by singl

20、e element probes or the phased-array technique) testing of seamless and welded (except submerged arc-welded) steel tubes, for verification of hydraulic leak-tightness. The testing technique is applied for the detection of predominantly longitudinal imperfections. Where applicable, Lamb-wave testing

21、may be applied at the discretion of the manufacturer. This International Standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 10 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5. 2 Normative references The following referen

The arc generated and the molten metal are protected from atmospheric contamination by the presence of a layer of flux.

31、d out on tubes after completion of all the primary production-process operations, such as rolling, heat treating, cold and hot working, sizing, straightening, etc. 4.2 The tubes to be tested shall be sufficiently straight to ensure the validity of the test. The surfaces shall be sufficiently free fr

32、om foreign matter which would interfere with the validity of the test. 4.3 This inspection shall be carried out by suitable trained operators qualified in accordance with ISO 9712, ISO 11484 or equivalent and supervised by competent personnel nominated by the manufacturer. In the case of third-party

33、 inspection, this shall be agreed between the purchaser and the manufacturer. The operating authorization issued by the employer shall be in accordance with a written procedure. Non-destructive testing operations shall be authorized by a Level 3 non-destructive testing individual approved by the emp

34、loyer. NOTE The definition of Levels 1, 2 and 3 can be found in appropriate standards, e.g. ISO 9712 and ISO 11484. BS ISO 10332:2010ISO 10332:2010(E) ISO 2010 All rights reserved 35 Method of test 5.1 The tubes shall be tested by using an ultrasonic shear-wave technique or Lamb-wave technique, if a

35、pplicable, for the detection of predominantly longitudinal imperfections. 5.2 During testing, the tubes and the transducer assembly shall be moved relative to each other so that the whole of the tube surface is scanned, with coverage calculated on the dimension of the transducer(s). The relative spe

36、ed of movement during testing shall not vary by more than 10 %. It is recognized that there may be a short length at both tube ends which cannot be tested. Any untested ends shall be dealt with in accordance with the requirements of the appropriate product standard (see also Annex A). In the case of

37、 electro-welded (EW) tubes, excluding welded stretch-reduced tubes, by agreement between the purchaser and manufacturer, verification of hydraulic leak-tightness of the weld zone only is permitted. In this case, the transducer assembly shall be correctly aligned with the weld seam so that the whole

38、length of the weld seam is scanned. 5.3 During testing, the tubes shall be scanned in two opposing directions of beam travel, unless otherwise agreed between the purchaser and manufacturer. 5.4 For the detection of longitudinal imperfections, the maximum width of each individual transducer measured

39、parallel to the major axis of the tube, shall be 25 mm. When using the Lamb-wave technique or phased-array technique, the maximum length of the transducer/active aperture shall be limited to 35 mm. 5.5 The ultrasonic test frequency of transducers to be used shall be in the range of 1 MHz to 15 MHz f

40、or shear-wave technique and in the range of 0,3 MHz to 1 MHz for the Lamb-wave technique, depending on the product condition and properties, the thickness, and the surface finishing of tubes under examination. 5.6 The equipment shall be capable of classifying tubes as either acceptable or suspect by

41、 means of an automated trigger/alarm level combined with a marking and/or sorting system. 6 Reference tube 6.1 General 6.1.1 The reference standards defined in this International Standard are convenient for the calibration of non-destructive testing equipment. The dimensions of these standards shoul

42、d not be construed as the minimum size of imperfection detectable by such equipment. 6.1.2 The ultrasonic equipment shall be calibrated using a longitudinal reference notch on the outside and inside surfaces or a reference hole drilled radially through the full thickness of a reference tube. The int

43、ernal notch shall not be used when the internal diameter of the tube is less than 15 mm, unless otherwise agreed between the purchaser and the manufacturer. 6.1.3 The reference tubes shall have the same nominal diameter and thickness and the same surface finish and delivery condition (e.g. as-rolled

44、 normalized, quenched and tempered) as the tubes to be tested, and shall have similar acoustic properties (for example, sound velocity, attenuation coefficient). 6.1.4 In order to obtain clearly distinguishable signals, the reference standard(s) shall be sufficiently separated from the ends of the

45、reference tubes and from each other. 6.2 Types of reference notches 6.2.1 The reference notches shall lie parallel to the major axis of the reference tube. BS ISO 10332:2010ISO 10332:2010(E) 4 ISO 2010 All rights reservedThe reference notches shall be of the “N” type (see Figure 1). The sides of the

46、 notch shall be nominally parallel and the bottom shall be nominally square to the sides. It is recognized that the bottom or the bottom corners of the notch may be rounded. Key w width d depth Figure 1 Reference notch forms (“N” type notch) 6.2.2 The reference notch shall be formed by machining, sp

47、ark erosion or other methods. 6.3 Dimensions of reference notches 6.3.1 Width, w The width of the reference notch (see Figure 1) shall not be greater than 1,0 mm. 6.3.2 Depth, d The depth of the reference notch (see Figure 1) shall be 12,5 % of the specified thickness with the following limitations:

48、 minimum notch depth: 0,5 mm; maximum notch depth: 1,5 mm. The tolerance on notch depth shall be 15 % of the nominal reference notch depth. 6.3.3 Notch length Unless otherwise specified by the product standard or agreed between the purchaser and the manufacturer, the length of the reference notch(es

49、) shall be greater than the width of the single transducer or the active aperture of the phased-array transducer, with a maximum of 50 mm. 6.4 Reference hole The reference hole shall be drilled through the wall, perpendicular to the surface of the tube; for welded pipe, it shall be drilled at the centre of the weld. The diameter of the reference holes related to the outside diameter of the tube shall not exceed the requirements of Table 1. The holes shall be formed by machining, spark erosion or other methods.
