The work of preparing International Standards is normally carried out through ISO technic
27、al 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 ISO, also take part in the work. ISO collaborates closely wi
28、th 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 2. The main task of technical committees is to prepare International Standards. Draft Inte
29、rnational Standards 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 document ma
30、y be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11961 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 5, Casing
31、, tubing and drill pipe. This second edition cancels and replaces the first edition (ISO 11961:1996), which has been extensively technically revised. It is the intention of ISO/TC 67 that either this edition or the previous edition of ISO 11961 be applicable, at the option of the purchaser (as defin
32、ed in 4.1.31), for a period of six months from the first day of the calendar quarter immediately following the date of publication of this edition, after which period the previous edition will no longer be applicable. vi Introduction This International Standard is based on API Spec 5D and API Spec 7
33、. Users of this International Standard should be aware that further or differing requirements may be needed for individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment or engineering solutions for
34、the individual application. This may be particularly applicable where there is innovative or developing technology. Where an alternative is offered, the vendor should identify any variations from this International Standard and provide details. This International Standard includes provisions of vari
35、ous natures. These are identified by the use of certain verbal forms: a) SHALL is used to indicate that a provision is MANDATORY; b) SHOULD is used to indicate that a provision is not mandatory, but RECOMMENDED as good practice; c) MAY is used to indicate that a provision is OPTIONAL. API Specificat
36、ion 5DP / ISO 11961 1 Petroleum and natural gas industries Steel drill pipe 1 Scope This International Standard specifies the technical delivery conditions for steel drill-pipes with upset pipe-body ends and weld-on tool joints for use in drilling and production operations in petroleum and natural g
37、as industries for three product specification levels (PSL-1, PSL-2 and PSL-3). The requirements for PSL-1 form the basis of this International Standard. The requirements that define different levels of standard technical requirements for PSL-2 and PSL-3 are in Annex G. This International Standard co
38、vers the following grades of drill-pipe: grade E drill-pipe; high-strength grades of drill-pipe, grades X, G and S. A typical drill-pipe configuration is given, showing main elements and lengths (see Figure B.1). The main dimensions and masses of the grades of drill-pipe are given in both SI units (
39、see Table A.1) and in USC units (see Table C.1). This International Standard can also be used for drill-pipe with tool joints not specified by ISO or API standards. By agreement between purchaser and manufacturer, this International Standard can also be applied to other drill-pipe body and/or tool-j
40、oint dimensions. This International Standard lists supplementary requirements that can optionally be agreed between purchaser and manufacturer, for testing, performance verification and non-destructive examination (see Annex E). This International Standard does not consider performance properties. N
41、OTE 1 In this International Standard, drill-pipe is designated by label 1, label 2, grade of material (E, X, G and S), upset type and type of rotary shouldered connection. Designations are used for the purpose of identification in ordering. NOTE 2 Reference can be made to ISO 10424-2 or API Spec 7-2
42、 for the detailed requirements for the threading of drill-pipe tool joints. NOTE 3 Reference can be made to API RP 7G for the performance properties of the drill-pipe. 2 Conformance 2.1 Dual citing of normative references In the interests of world-wide application of this International Standard, Tec
43、hnical Committee ISO/TC 67 has decided, after detailed technical analysis, that certain of the normative documents listed in Clause 3 and prepared by ISO/TC 67 or another ISO Technical Committee are interchangeable in the context of the relevant requirement with the relevant document prepared by the
44、 American Petroleum Institute (API), the American Society for Testing and Materials (ASTM) and the American National Standards Institute (ANSI). These latter documents are cited in the running text following the ISO reference and preceded by or, for example ISO XXXX or API YYYY. Application of an al
45、ternative normative document cited in this manner will lead to technical results different from the use of the preceding ISO reference. However, both results are acceptable and these documents are thus considered interchangeable in practice. 2 Specification for Drill Pipe 2.2 Units of measurement In
46、 this International Standard, data are expressed in both the International System (SI) of units and the United States Customary (USC) system of units. Separate tables for data expressed in SI units and USC units are in Annex A and Annex C, respectively. Figures are in Annex B and express data in bot
47、h SI and USC units. For a specific order item, it is intended that only one system of units be used, without combining data expressed in the other system. Products manufactured to specifications expressed in either of these unit systems shall be considered equivalent and totally interchangeable. Con
48、sequently, compliance with the requirements of this International Standard as expressed in one system provides compliance with requirements expressed in the other system. For data expressed in the SI system, a comma is used as the decimal separator and a space as the thousands separator. For data ex
49、pressed in the USC system, a dot (on the line) is used as the decimal separator and a space as the thousands separator. In the text, data in SI units are followed by data in USC units in brackets. NOTE The procedures used to convert from USC units to SI units are given in informative Annex F. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendment) applies. ISO 6506-1, Met
