24、 4 Introduction This International Standard is based on API Spec 7, Specification for 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 inhi
25、bit a vendor from offering, or the purchaser from accepting, alternative equipment 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 variatio
26、ns from this International Standard and provide details. DIN EN ISO 10424-2:2008-07 EN ISO 10424-2:2007 (E) 5 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 threads and thre
27、ad 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 interested parties for spe
28、cial 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 internationally suppor
29、ted 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 are given in the bo
30、dy 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 and USC units used
31、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 compliance with requir
32、ements 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 separator. In the text,
33、data in SI units are followed by data in USC units in brackets. 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 documen
