1.1 本规范涵盖了烟气脱硫（FGD）设备金属部件的设计和制造，包括吸收器、储罐、烟囱衬里、管道系统和相关设备，这些设备将进行衬里以防腐蚀或耐磨，或两者兼而有之。 1.2 限制: 1.2.1 本规范旨在定义烟气脱硫系统部件保护衬里成功应用和性能的设计考虑因素。 1.2.2 它不包括烟气脱硫部件的结构性能。 1.2.3 它不包括金属衬里的使用。 1.3 本规范规定了衬砌工程的最低要求。 如果制造商的说明和建议与本规范不同，则应在开始制造之前解决这些差异。 1.4 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。 1.5 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。 1.6 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 the design and fabrication of metal components for flue gas desulfurization (FGD) equipment, including absorbers, tanks, chimney liners, ductwork and associated equipment that are to be lined for corrosion or abrasion resistance, or both. 1.2 Limitations: 1.2.1 This specification is intended only to define the design considerations for successful application and performance of protective linings for FGD system components. 1.2.2 It does not cover structural performance of FGD components. 1.2.3 It does not cover use of metallic linings. 1.3 This specification represents the minimum requirements for lining work. In cases in which the manufacturer's instructions and recommendations differ from this specification, these differences shall be resolved before fabrication is started. 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 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.
