stainless steel butt-weld pipe fittings (butt-weld fittings). Butt-weld
pipe fittings are under 14 inches in outside diameter (based on nominal
pipe size), whether finished or unfinished. The product encompasses all
grades of stainless steel and ``commodity'' and ``specialty'' fittings.
Specifically excluded from the definition are threaded, grooved, and bolted fittings, and fittings
made from any material other than stainless steel.
The butt-weld fittings subject to this order are generally

specification for Wrought Austenitic Stainless Steel Piping Fittings,
or its foreign equivalents (e.g., DIN or JIS specifications). This
specification covers two general classes of fittings, WP and CR, of
wrought austenitic stainless steel fittings of seamless and welded
construction covered by the latest revision of ANSI B16.9, ANSI B16.11,
and ANSI B16.28. Butt-weld fittings manufactured to specification ASTM
A774, or its foreign equivalents, are also covered by this order.
This order does not apply to cast fittings. Cast austenitic
stainless steel pipe fittings are covered by specifications A351/A351M,
A743/743M, and A744/A744M.
The butt-weld fittings subject to this order are currently
