1.1 本规范涵盖镍（UNS N02200）、低碳镍（UNS N02201）和镍铜合金（UNS N04400），其形式为焊接和退火或焊接和应力消除管，用于一般腐蚀服务和机械应用。 1.2 本规范涵盖附表5S、10S和40S至30英寸中的外径和标称壁管。ANSI B36.19中所示的标称管道尺寸（见 表1 )和规格 B775 （参见 表1 ). 可提供其他尺寸的管道，前提是此类管道符合本规范的所有其他要求。 1.3 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.4 以下预防性警告仅适用于试验方法部分第节 13 ，本规范: 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。 1.5 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 covers nickel (UNS N02200), low carbon nickel (UNS N02201) and nickel copper alloy (UNS N04400) in the form of welded and annealed or welded and stress relieved pipe intended for general corrosive service and for mechanical applications. 1.2 This specification covers outside diameter and nominal wall pipe in Schedules 5S, 10S, and 40S through 30-in. nominal pipe size shown in ANSI B36.19 (see Table 1 ) and Specification B775 (see Table 1 ). Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 The following precautionary caveat pertains only to the test methods portion, Section 13 , of this specification: This standard does not purport to address all of the safety problems, 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. 1.5 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.
