Standard Specification for MRS-Rated Metric- and Inch-sized Crosslinked Polyethylene (PEX) Pressure Pipe for Oil and Gas Producing Applications 石油和天然气生产用MRS级公制和英制交联聚乙烯(PEX)压力管标准规范
发布日期: 2023-02-01
1.1 本规范涵盖交联聚乙烯(PEX)管,其外径控制在公制管尺寸(DN 16至1000)和英制管尺寸(NPS 3至54)内,且额定压力(参见 附录X1 )使用ISO MRS评级系统。本规范适用于各种工艺制造的PEX管道,只要该工艺制造的聚乙烯管道满足本规范的所有要求。包括材料、工艺、紫外线防护、尺寸、静水压力、耐化学性、最低工作温度、交联度、挤压性的要求和试验方法- 关闭和静水爆破压力。还给出了管道标记的要求。本规范涵盖的管道适用于压力或非压力油气生产应用,如输送油、干气或湿气、集气、多相流体和非饮用油田水。本规范不包括气体分配应用。 注1: 管道尺寸大于NPS 8的集气应用可能需要遵守PHMSA设计、材料和安装要求。 1.2 本规范还包括使用聚乙烯电熔配件制造的合格接头的要求(如规范 第3373页 )和PEX管。与按照本规范制造的PEX管一起使用的管件符合规范 F2829年 。安装注意事项 第2.2页 . 注2: NPS管件不得用于DN尺寸的管道,DN尺寸的管件不得用于NPS管道。 1.3 本规范的正文引用了注释、脚注和附录,提供了解释性材料。这些注释和脚注(不包括表和图中的注释和脚注)不应视为本规范的要求。 1.4 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值。 每个系统中所述的值不一定完全相等;因此,为了确保符合标准,每个系统应独立使用,两个系统的值不得合并。 1.4.1 为了与ISO 9080保持一致,MRS值只能以SI单位转换为管道材料名称(例如,MRS为8MPa的管道形式的PEX材料被指定为PEX 80)。 1.5 本标准并不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建立适当的安全、健康和环境实践,并确定监管限制的适用性。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒(TBT)委员会发布的《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。
1.1 This specification covers crosslinked polyethylene (PEX) pipe that is outside diameter controlled in metric pipe sizes (DN 16 to 1000) and inch pipe sizes (NPS 3 to 54), and pressure rated (see Appendix X1 ) using the ISO MRS rating system. This specification is intended for PEX pipe made by various processes, as long as the PEX pipe made by that process meets all the requirements of this specification. Included are requirements and test methods for material, workmanship, UV protection, dimensions, hydrostatic sustained pressure, chemical resistance, minimum operating temperature, degree of crosslinking, squeeze-off, and hydrostatic burst pressure. Requirements for pipe markings are also given. The pipe covered by this specification is intended for pressure or non-pressure oil and gas producing applications such as conveying oil, dry or wet gas, gas gathering, multiphase fluids, and non-potable oilfield water. This specification does not cover gas distribution applications. Note 1: Gas gathering applications where the pipe size is greater than NPS 8 may be subject to PHMSA design, material, and installation requirements. 1.2 This specification also includes requirements for qualifying joints made using polyethylene electrofusion fittings (such as Specification F3373 ) and PEX pipe. Fittings to be used with PEX pipe manufactured to this specification are in Specification F2829 . Installation considerations are in X2.2 . Note 2: NPS fittings should not be used for DN sized pipe, and DN sized fittings should not be used for NPS pipe. 1.3 The text of this specification references notes, footnotes, and appendixes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) should not be considered as requirements of the specification. 1.4 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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.4.1 For consistency with ISO 9080, MRS values shall only be in SI units for conversion to the pipe material designation (for example PEX material in pipe form with an MRS of 8 MPa is designated a PEX 80. 1.5 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. 1.6 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.
