1.1 本规范涵盖了用于输送石油、干气或湿气、多相流体和非饮用油田水等流体的压力或非压力油气生产应用的聚酰胺-12（PA12）材料、管道和配件的要求和试验方法。本规范不包括用于气体分配应用的管道。 1.1.1 参见规范 第2785页 用于分配天然气或与液化石油气一起使用的PA12管道和配件。 1.1.2 本规范所涵盖的管道和配件不得使用锥形管螺纹连接。对接熔接应按照实践进行 F3372美元 厂内质量控制程序在 附录X1 。中讨论了设计注意事项 附录X2 . 1.2 单位- 以国际单位制或英寸磅单位表示的数值应单独视为标准。每个系统中规定的值可能不是精确的等效值；因此，每个系统应独立于其他系统使用。将两个系统的值合并可能导致不符合标准 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。

1.1 This specification covers requirements and test methods for polyamide-12 (PA12) materials, pipe and fittings for pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water. This specification does not cover pipe for gas distribution applications. 1.1.1 See Specification F2785 for PA12 pipe and fittings intended for use in the distribution of natural gas, or for use with liquefied petroleum gas. 1.1.2 Pipe and fittings covered by this specification shall not be joined using taper pipe threads. Butt fusion joining shall be done in accordance with Practice F3372 . In-plant quality control programs are described in Appendix X1 . Design considerations are discussed in Appendix X2 . 1.2 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
