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 metalic linings.

1.3 This specification represents the minimum requirements for lining work. In cases where the manufacturer's instructions and recommendations differ from this specification, these differences must be resolved before fabrication is started.

1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
