Description

ASME B16.5 Socket Weld Flange, ASME/ANSI Socket Weld Raised Face Flange, B16.5 SW Flange, ANSI SWRF Flange, BS 4504 Socket Weld Flange

Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that is inserted to the flange. Socket Weld flanges were initially developed for use on small-size high-pressure piping.
