11、05 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 9330-4:2000(E) iv ISO 2000 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing Internat
12、ional 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. International organizations, governmental and non-governmental, in liaison with I
13、SO, 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 the rules given in the ISO/IEC Directives, Part 3. Draft International Standard
14、s adopted by the technical committees are circulated 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 part of ISO 9330 may be the s
15、ubject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 9330-4 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 19, Technical delivery conditions for steel tubes for pressure purposes. ISO 9330 consists
16、 of the following parts, under the general title Welded steel tubes for pressure purposes Technical delivery conditions: ?Part 1: Unalloyed steel tubes with specified room temperature properties ?Part 2: Electric resistance and induction welded unalloyed and alloyed steel tubes with specified elevat
17、ed temperature properties ?Part 3: Electric resistance and induction welded unalloyed and alloyed steel tubes with specified low temperature properties ?Part 4: Submerged arc-welded unalloyed and alloyed steel tubes with specified elevated temperature properties ?Part 5: Submerged arc-welded unalloy
18、ed and alloyed steel tubes with specified low temperature properties ?Part 6: Longitudinally welded austenitic stainless steel tubes Annex A of this part of ISO 9330 is for information only.

20、alloyed and alloyed steel tubes with specified elevated temperature properties 1Scope This part of ISO 9330 specifies the technical delivery conditions for submerged arc-welded tubes of circular cross- section, made of unalloyed or alloyed steel with specified elevated temperature properties. These
21、tubes are intended for pressure purposes in cases when the material is also subjected to elevated temperatures, e.g. for the construction of steam generating equipment and for interconnecting pipework. The requirements of appropriate international application standards and relevant national legal re
22、gulations shall be taken into account by the user. For boilers and pressure vessels International Standards ISO 831, ISO 2604 and ISO 5730 are available. For the general technical delivery requirements, see ISO 404. NOTEThe English words “tube” and “pipe” are synonymous. 2Normative references The fo

43、ll be informed of the steelmaking process used. Steels may be cast in ingots or may be strand cast. When steels of different grades are sequentially strand cast identification of the resultant transition material is required. The producer shall remove the transition material by an established proced
44、ure that positively separates the grades. 5.2Deoxidation process Steels intended for the production of tubes covered by this part of ISO 9330 shall be fully-killed. 5.3Product-making process for tubes A welded tube is obtained by shaping a flat-rolled product and then welding the edges. The weld may
45、 be longitudinal or helical. Tubes shall be submerged arc-welded (SAW) using at least one run on the inside and one run on the outside of the tube. Unless otherwise agreed, the process of manufacture is left to the discretion of the manufacturer, provided that the welding method and welder/welding o
46、perator have been approved in accordance with a qualified procedure. Tubes covered by this part of ISO 9330 may be hot finished or cold finished. The terms “hot finished” and “cold finished” apply to the condition of the tube before it is heat treated, if applicable. 5.4Delivery condition 5.4.1Tubes
47、 covered by this part of ISO 9330 shall be delivered in accordance with Table 1 and when appropriate the heat treatment conditions indicated in Table 2. 5.4.2By agreement between the purchaser and the manufacturer the tubes may be delivered in a condition other than the final delivery condition in w
48、hich case they shall be suitable for subsequent manipulation and the purchaser shall be informed of any treatment necessary to obtain the specified properties.
