ASTM D 4618:1992

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 and health practices and determine the applicability of regulatory limitations prior to use.
