ANSI B16.5 SWRF Flange, ASTM A182 F304 Stainless Steel Socket Weld
Flanges
A182 F304 SW flange is a type of flange made from A182 F304 stainless steel material.
SW stands for Socket Weld, which means that this type of flange has
a socket that is welded onto a pipe, creating a smooth bore
surface. This flange is commonly used in high-pressure applications
where welding is preferred over threading. It is also known for its
corrosion resistance and durability.

Applications of pipe flanges
Pipe flanges are widely used in pipe fittings of various
industrial, commercial and residential applications. Pipe flanges
can be customized to suit your application with various machining
details. These pipe flanges have been used extensively in:
UHV applications
A. Hydraulic control systems for turbine generators
B. High pressure ground support missile systems
C. Nuclear and conventional power plant applications etc.
