23、Foreword 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 which a t
24、echnical 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 matters
25、 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 circulate
26、d 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 responsible
27、for identifying any or all such patent rights. ISO 10424-2 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production equipment. ISO 10424 consists of the following pa
28、rts, under the general title Petroleum and natural gas industries Rotary drilling equipment: Part 1: Rotary drill stem elements Part 2: Threading and gauging of rotary shouldered thread connections EN ISO 10424-2:2007vi Introduction This International Standard is based on API Spec 7, Specification f
29、or rotary drill stem elements. 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
30、or engineering solutions for 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. EN ISO 10424-2:20071Petrol
31、eum and natural gas industries Rotary drilling equipment Part 2: Threading and gauging of rotary shouldered thread connections 1 Scope This part of ISO 10424 specifies requirements on rotary shouldered connections for use in petroleum and natural gas industries, including dimensional requirements on
32、 threads and thread gauges, stipulations on gauging practice, gauge specifications, as well as instruments and methods for inspection of thread connections. These connections are intended primarily for use in drill-string components. Other supplementary specifications can be agreed between intereste
33、d parties for special tolerance requirements, qualification, testing, inspection and finishing. This part of ISO 10424 is applicable to the following preferred rotary shouldered connection designs: a) number (NC) style; b) regular (REG) style; c) full hole (FH) style. These are traceable to an inter
34、nationally supported system of gauges and calibration 2 Conformance Units of measurement In this part of ISO 10424, 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 ar
35、e given in the body of this part of ISO 10424 and Annex A, respectively. Figures express data in both 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. Annex G provides the conversion between SI an
36、d USC units used in this part of ISO 10424. Products manufactured to specifications expressed in either of these unit systems shall be considered equivalent and totally interchangeable. Consequently, compliance with the requirements of this part of ISO 10424 as expressed in one system provides compl
37、iance 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 expressed in the USC system, a dot (on the line) is used as the decimal separator and a space as the thousands separat
38、or. In the text, data in SI units are followed by data in USC units in brackets.
