18、reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of 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 w

19、hich a technical committee has been established has the right to be represented on that committee. International 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

20、 matters of electrotechnical standardization. International Standards are drafted in accordance with 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 c

21、irculated to the member bodies for voting. Publication as an International Standard requires approval 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 resp

ISO 10893-12 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical delivery conditions for steel tubes for pressure purposes.

30、ged arc-welded) steel tubes 1 Scope This part of ISO 10893 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corre

31、sponding calibration procedures. NOTE 1 Full peripheral testing does not necessarily mean that 100 % of the tube surface is scanned. NOTE 2 This test can be carried out simultaneously with full peripheral ultrasonic testing for the detection of laminar imperfections (see ISO 10893-8) using the same

32、ultrasonic transducers for both inspection requirements. Under these circumstances, the minimum lamination size under detection determines the percentage of the tube surface for scanning, according to ISO 10893-8. This part of ISO 10893 can also be applicable to the testing of circular hollow sectio

33、ns. This part of ISO 10893 is applicable to the thickness measurement of tubes with a specified outside diameter equal to or greater than 25,4 mm and a minimum wall thickness of 2,6 mm, unless otherwise agreed on. 2 Normative references The following referenced documents are indispensable for the ap

34、plication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

36、in ISO 5577 and ISO 11484 and the following apply. 3.1 reference tube tube or length of tube used for calibration purposes 3.2 reference sample sample (e.g. segment of tube, plate or strip) used for calibration purposes NOTE Only the term “reference tube” is used in this part of ISO 10893, also cove

37、ring the term “reference sample”. 3.3 tube hollow long product open at both ends, of any cross-sectional shape 3.4 seamless tube tube made by piercing a solid product to obtain a tube hollow, which is further processed, either hot or cold, into its final dimensions 3.5 welded tube tube made by formi

38、ng a hollow profile from a flat product and welding adjacent edges together, and which after welding can be further processed, either hot or cold, into its final dimensions 3.6 electric welded tube tube made by pressure welding, in a continuous or non-continuous process, in which strip is formed col

39、d into a hollow profile and the seam weld made by heating the adjacent edges through the resistance to the passage of high- or low-frequency current, and pressing the edges together NOTE The electric current can be applied either by direct electrode contact or by induction. 3.7 manufacturer organiza

41、 General requirements 4.1 Unless otherwise specified by the product standard or agreed between purchaser and manufacturer, an ultrasonic test shall be carried out on tubes after completion of all the primary production process operations (rolling, heat treating, cold and hot working, sizing and prim

42、ary straightening, etc.). 4.2 The tubes under test shall be sufficiently straight to ensure the validity of the test. The surfaces shall be free of foreign matter, which can interfere with the validity of the test. 4.3 This test shall be carried out by suitably trained operators, qualified in accord

43、ance with ISO 9712, ISO 11484, or equivalent, and supervised by competent personnel nominated by the manufacturer. In the case of third-party inspection, this shall be agreed on by the purchaser and manufacturer. BS EN ISO 10893-12:2011ISO 10893-12:2011(E) ISO 2011 All rights reserved 3The operating

44、 authorization issued by the employer shall be according to a written procedure. Non-destructive testing (NDT) operations shall be authorized by a level 3 NDT individual approved by the employer. NOTE The definition of levels 1, 2 and 3 can be found in appropriate International Standards, e.g. ISO 9

45、712 and ISO 11484. 5 Test method 5.1 The tube shall be tested using the ultrasonic single or multiple pulse echo technique, with piezoelectric or electromagnetic transducers. The ultrasound shall be transmitted in the direction normal to the tube surface, to determine that the tube thickness meets t

46、he specified requirements. 5.2 During testing, the tubes and the probe assembly shall be moved relative to each other such that (with the exception provided in Note 2 of Clause 1) the tube surface shall be scanned over equidistant non-coincident helical paths along the entire length of the tube. Unl

47、ess specified in the product standards or agreed on by the manufacturer and purchaser, the minimum coverage shall be at the manufacturers discretion according to his manufacturing process, but shall be not less than 10 % of the surface area. NOTE Other scanning routes can be used by agreement betwee

48、n the purchaser and manufacturer. 5.3 The suggested maximum width of each transducer, or each active aperture when using phased array transducers, should be 25 mm measured in any direction. However, manufacturers may use larger transducers provided they can demonstrate their capability for detecting

49、 the adopted reference standard; on request, this capability shall be demonstrated. 5.4 The equipment shall be capable of classifying tubes as either acceptable or suspect by means of an automated trigger/alarm level combined with a marking and/or recording and/or sorting system. 6 Reference tube 6.1 The reference tube (or partly scanned tube) shall have the same nominal diameter and thickness, same surface finish, heat treatment and delivery condition (e.g. as-rolled, normalized, quenched and tempered) as th
