Product Description

B16.5 A182 F11 Cl3000 SWRF Flange Alloy 

 Socket Weld flanges were initially developed for use on small-size high pressure piping. Their static strength is equal to Slip On flanges, but their fatigue strength 50% greater than double-welded Slip On flanges.
The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.
Socket weld flange dimensions are covered in ASME B16.5 - which covers Pipe Flanges and Flanged Fittings for size NPS ½" to 24" for above NPS 26" to 60" it should be as per ASME B16.47. Socket weld flanges are available only up to 3″ NPS Size. Working pressure from class 1500 to class 1500.
During a dimensional inspection of the socket weld flange, you should check for
Outer & Inner Diameter of body
Bolt Circle & Bolt Hole Diameter
Depth of the socket
Length of the Hub and
Straightness and alignment of the bolt hole
Available materials in stainless steel, carbon steel, alloy steel and duplex steel.
