This NACE International standard represents a consensus of those individual members

who have reviewed this document, its scope, and provisions. Its acceptance does not in

any respect preclude anyone, whether he or she has adopted the standard or not, from

manufacturing, marketing, purchasing, or using products, processes, or procedures not

ABSTRACT

This standard practice provides technical

and quality assurance guidelines for the fab-

rication, welding, and installation of clad

plate bonded in air pollution control or other

equipment such as ue gas desulfurization

(FGD) systems, ducts, and stacks. Also in-

cluded are procedures for the qualication of

welders and the inspection and repair of

welds, as well as an appendix on handling

clad plate components. Detailed gures on

weld joint design are included.

This standard is intended for use by archi-

tect-engineers, designers, fabricators, and

personnel from electric utilities.

Foreword

The purpose of this standard 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

equipment. It is intended for use by personnel including architect-engineers, designers,

fabricators, and personnel from electric utilities.

This standard was originally prepared in 1999 by NACE Task Group T-5F-6, a component

of Unit Committee T-5F, “Corrosion Problems Associated with Pollution Control.” It was

revised in 2004, 2009, and 2018 by Task Group (TG) 199, “Stainless Chromium-Nickel

Steel and Nickel-Alloy Roll-Bonded and Explosion-Bonded Clad Plate for Air Pollution

Control Equipment, Installation: Review of NACE SP0199.” TG 199 is administered by

Specic Technology Group (STG) 45, “Pollution Control, Waste Incineration, and Process

Waste.” This standard is issued by NACE International under the auspices of STG 45.

In NACE standards, the terms “shall,”

“must,” “should,” and “may” are used

in accordance with the denitions of

these terms in the NACE Publications

Style Manual. The terms “shall” and

“must” are used to state a requirement,

and are considered mandatory. The

term “should” is used to state some-

thing good and is recommended, but is

not considered mandatory. The term

“may” is used to state something con-

sidered optional.
