The purpose of this standard recommended practice is to provide technical and quality assurance guidelines for the fabrication, welding, and installation of stainless chromium-nickel steel and nickel-alloy roll-bonded and explosion-bonded clad plate in air pollution control and other process equipment. It is intended for use by personnel including architect engineers, designers, fabricators, and personnel from electric utilities and firms in the process industries.

This standard was originally prepared in 1999 by NACE Task Group T-5F-6, a component of Unit Committee T-5F on Corrosion Problems Associated with Pollution Control. It was revised in 2004 by Task Group 199 on the Installation of Stainless Chromium-Nickel Steel and Nickel-Alloy Roll-Bonded and Explosion-Bonded Clad Plate in Air Pollution Control Equipment. This Task Group is administered by Specific Technology Group (STG) 45 on Pollution Control. This standard is issued by NACE International under the auspices of STG 45.

1.1 This standard provides technical and quality assurance guidelines for the fabrication, welding, and installation of stainless chromium-nickel steel and nickel-alloy roll-bonded and explosion-bonded clad plate conforming to ASTM<1l A 2641 or A 2652 in air pollution control equipment. Included are flue gas desulfurization (FGD) absorbers, ducts, stacks, and other process equipment. It is intended to be the basis for preparation of a specification to be agreed on by contracting parties.

1.2 For the purposes of this standard, the term alloy is used to describe either the stainless chromium-nickel steel or nickel-alloy portion of the clad-steel plate as well as the equivalent solid stainless chromium-nickel steel or nickel-alloy material.

1.3 It is the responsibility of users of this standard to determine the suitability of the construction materials specified.
