1.1 本规范 2. 镍和镍钴合金焊接管盖（UNS N10001；UNS N10242；UNS N10665；UNS N12160；UNS N10624；UNS N10629；UNS N10675；UNS N10276；UNS N06455；UNS N06007；UNS N06975；UNS N08320；UNS N06002；UNS N06022；UNS N06035；UNS N06044；UNS N06058；UNS N06059；UNS N06200；UNS N06235；UNS N10362；UNS N06985；UNS N06030；UNS UNS R30556；UNS N08031；UNS N08034；UNS N06230；UNS N06686；UNS N06210；和UNS R20033） 3. 如所示 表1 . 1.2 本规范涵盖附表5S、10S、40S和80S至8-in中的管道。ANSI B36.19中规定的标称管道尺寸和更大尺寸（见 表2 ). 1.3 管道包括以下两类: 1.3.1 I类- 焊接和固溶退火或焊接和定尺寸和固溶退火。 1.3.2 II类- 焊接、冷加工和固溶退火。 1.4 所有管道应在固溶退火和除垢条件下提供。当使用大气控制时，不需要除垢。 1.5 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。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任熟悉所有危险，包括制造商提供的本产品/材料的适当安全数据表（SDS）中确定的危险，建立适当的安全、健康和环境实践，并在使用前确定监管限制的适用性。 1.7 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《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification 2 covers welded pipe of nickel and nickel-cobalt alloys (UNS N10001; UNS N10242; UNS N10665; UNS N12160; UNS N10624; UNS N10629; UNS N10675; UNS N10276; UNS N06455; UNS N06007; UNS N06975; UNS N08320; UNS N06002; UNS N06022; UNS N06035; UNS N06044; UNS N06058; UNS N06059; UNS N06200; UNS N06235; UNS N10362; UNS N06985; UNS N06030; UNS R30556; UNS N08031; UNS N08034; UNS N06230; UNS N06686; UNS N06210; and UNS R20033) 3 as shown in Table 1 . 1.2 This specification covers pipe in Schedules 5S, 10S, 40S, and 80S through 8-in. nominal pipe size and larger as set forth in ANSI B36.19 (see Table 2 ). 1.3 Two classes of pipe are covered as follows: 1.3.1 Class I— As welded and solution annealed or welded and sized and solution annealed. 1.3.2 Class II— Welded, cold worked, and solution annealed. 1.4 All pipe shall be furnished in the solution annealed and descaled condition. When atmosphere control is used, descaling is not necessary. 1.5 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. 1.6 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.7 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.
