1.1 本规范涵盖了标称壁厚和最小壁厚的焊管，以及由中列出的镍合金制成的焊接管和冷加工管 表1 . 预期用途包括强度和高温强度为预期属性的应用。例如液压控制管路、锅炉、热交换器和太阳能吸收器。 1.2 管子应在以下条件之一下供应:；冷加工、冷加工和沉淀硬化、固溶退火加沉淀硬化或固溶退火和除垢条件。当使用大气控制时，不需要除垢。 1.3 本规范涵盖管道 1. / 8. 至6英寸。外径为（3.2至152.4 mm），0.015至0.148 in。（0.41至3.7 mm），包括壁厚。 1.4 以英寸表示的值- 磅单位应视为标准单位。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。 1.5 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。 1.6 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《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 nominal and minimum wall-thickness welded tubes and welded and cold worked tubes made from the nickel alloys listed in Table 1 . Anticipated uses cover applications where strength and strength at elevated temperatures are desired attributes. Some examples are hydraulic control lines, boilers, heat exchangers, and solar absorbers. 1.2 Tube shall be supplied in one of the following conditions; cold worked, cold worked and precipitation hardened, solution annealed plus precipitation hardened, or solution annealed and descaled conditions. When atmosphere control is used, descaling is not necessary. 1.3 This specification covers tube 1 / 8 to 6 in. (3.2 to 152.4 mm) in outside diameter and 0.015 to 0.148 in. (0.41 to 3.7 mm) inclusive in wall thickness. 1.4 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. 1.5 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 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. 1.6 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.
