HEUBACH INTERNATIONAL offers a wide array of 254 SMO
Flanges, which is used in varied industrial and
commercial sectors and is quality assured. SMO 254 Slip
On Flanges (UNS S31254) is often used
in Flue gas desulfurization scrubbers, Components used in
petroleum production, Food processing equipment and more. In some
applications, SMO 254 Spectacle Blind Flanges has been found to
be a more cost effective substitute for high nickel and titanium
alloys. SMO 254 Weld Neck Flanges is compatible
with the common austenitic stainless steels. SMO 254 Lap Joint
Flanges is developed for use in halide – containing environment
such as seawater, hydrochloric acid and contaminated sulphuric
acid. Meanwhile, these SMO 254 Socket Weld
Flanges are also being offered in different sizes and
shapes to our customers.
