ASME B16.5 A182 F44 / Alloy 254 SMO / 1.4547 / UNS S31254 SS WN RF
Flange
ASTM A182 F44 Flange is Material to F44 Super Austenitic Stainless
Steel is described as a 6% Mo Flanges super austenitic stainless
steel, which is designed for the maximum resistant to crevice
corrosion and pitting. It comes with high levels of molybdenum,
chromium, nitrogen and is great for high chloride environments like
bleach plants and chloride processing streams. There are
different standards for sizing such as ASME, ANSI, DIN and other
international standards.
ASTM A182 F44 are manufactured in various production forms such as
forged, bolted, threaded and flat flanges. There are also different
functional types such as sliding flanges, ring flanges, hole
flanges, Weld Neck Flange and blind flanges. Blind flanges also
come in different varieties, such as the SMO 254 Spectacle blind
flange. Each flange type has a purpose to fulfill in an
application. The face type of the flange is also different.

Various Kinds of Flanges we can supply as below
1. Slip-on Flanges.
Slip-on Flanges have a lower initial cost than welding neck flanges
because they require less accuracy in cutting pipe to length, and
they provide a greater ease of alignment in assembly. However,
their calculated strength under internal pressure is approximately
2/3's the strength of welding neck flanges, and their life under
fatigue is 1/3 shorter. Slip-on Flanges are limited to 1/2" to 2½"
sizes in 1500lbs standard.
2. Threaded Flanges
Threaded Flanges are used for special applications. They can be
assembled without welding and can be used in extremely high
pressure services--at or near atmospheric pressure--where alloy
steel is essential for strength. Threaded flanges are not suited
for conditions involving temperature or bending stresses, or under
cyclic conditions where leakage through the threads may occur.
3. Weld Neck Flanges
Weld Neck Flanges have a long tapered hub and gradual transition of
thickness in the region of the butt weld joining them to the pipe.
The tapered hub provides important reinforcement to the flange and
resistance to dishing. This type of flange is preferred for severe
service conditions resulting from high pressure, sub-zero or high
temperatures.
4. Blind Flanges
Blind Flanges are used to blank off the ends of piping, valves and
pressure vessel openings. Blind Flanges can handle high stress from
internal pressure and bolt loading since the maximum stresses in
the blind flange are bending stresses at the center.
5. Socket Weld Flanges
Socket Weld Flanges were developed for use on small size high
pressure piping. With an internal weld, socket weld flanges are
stronger and have greater fatigue strength than double welding a
slip-on flange. Smooth bore conditions can be easily attained by
grinding the internal weld. This flange is commonly used in
chemical process piping.
6. Lap Joint Flanges
Lap Joint Flanges are used with lap joint stubs. Lap joint flanges
are commonly used in carbon or low alloy steel piping systems that
need to be frequently dismantled for inspection and cleaning. They
should not be used at any points where severe bending stresses
occur.
Application
254 SMO Weld Neck Flanges 254 SMO WN Flanges are widely used in high-pressure piping systems and can be easily recognised by the
long tapered hub. The size of the bore hole is usually equal to the size of the pipe. Alloy 254 SMO Weld Neck Flanges and A182 F44 S31254
Weld Neck Flanges is in ready stock with Siddhagiri Metals and Tubes.
