What Is Socket Weld Flange?


ASME B16.5 socket weld flange is the specification of socket weld flanges from ½ inches to 24 inches in diameter. They can come in different pressure classes. class 150 socket weld flange dimensions differ depending on the nominal size. SWRF Flanges with a nominal size of 8 can have a hub at bevel diameter as 8.63. Socket weld Raised Face Flanges are the ones that come with a raised face for easy installation. Socket weld flange a105 is made up of the alloy a105 material. Any socket weld pipe flange produces flanges with a socket attached to them in an annealed condition. This allows for extra grip where the pipes are sent into the socket and fillet welded at both ends.

Do Socket Weld Flanges Have A Schedule?

asme b16.5 socket weld flange is comparatively light weight and corrosion resistant to other type of steel flanges. swrf flange weight varies with the material, size and the shape of the flange. ANSI B16.5 Class 150 Socket weld Flanges range from NPS ½ to NPS 24 specification and belong to the pressure class 150. Stainless Steel Socket weld Flanges are widely used in different applications. Socket weld raised face flange offers more surface to work on and thus providing extra grip on the welding side. Flat Face Socket weld Flanges are applied in conditions where there is no space or need for a raised face.


What Is The Difference Between A Weld Neck Flange And A Slip On Flange?

  • asme b16.5 socket weld flange is used to connect different diameters of pipes socket weld rtj flange with the ring type joint is used for tight sealing of systems. socket weld sae flange is made up of a nickel chromium molybdenum alloy. There are more specifications and applications of the Stainless Steel Socket Weld Flange in the market.

  • Slip on Flanges are used in applications where the two pipes have to be held together with bolt and nut. The raised face helps bolting. They have to be welded on either side with fillet welding as well.
