General
This standard provides technical and quality assurance guidelines for handling and installing nickel alloy, stainless steel, and titanium linings in air pollution control equipment such as FGD systems, ducts, and stacks.
The guidelines in this standard are also applicable to installation of thin, high-performance metallic linings in a wide variety of other process equipment. However, titanium welding procedures contained herein are only applicable to seal welds in air pollution control equipment.
It is the responsibility of users of this standard to determine the suitability of construction materials specified for particular applications.
This standard is applicable to wallpapering materials of 1.6 to 3.2 mm (0.063 to 0.13 in) thickness applied as linings over new or existing metallic structures. General safety requirements to perform this work are beyond the scope of this standard. It is assumed that users will incorporate specific safety requirements in accordance with their individual needs.
New and improved welding techniques as well as new alloys applicable to wallpaper installation are being developed. References to specific weld designs and techniques in this standard are not intended to preclude the use of newer technology. Use of alternative techniques shall be mutually agreed on by all contractual parties after adequate engineering analysis.
The corresponding ASME(1) material specifications may be used instead of the ASTM(2) material specifications cited in this standard.
While the techniques described in this standard have demonstrated high levels of success, some extreme environmental and/or design conditions encountered in the use of air pollution control equipment can result in corrosive conditions so severe that even the most corrosion-resistant construction material will occasionally fail. Such failures generally affect a relatively small percentage of the total lined surface and may require periodic maintenance.
