Socket Weld Flanges Description

Other Name: B16.5 CLASS 150 300 600 900 SOCKET WELD FLANGES RF, SWRF FLANGES, ASTM A105, SCH40, SCH80, STD

Socket-weld pipe flanges are typically used on smaller sizes of high pressure pipes. These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top.

Standard: B16.5 SOCKET WELD FLANGES RF
Model: SWRF FLANGES SCH40 SCH80 STD
Material: ASTM A105, Carbon Steel, High Nickel Alloys
Process: Forged, Forging
Packing: Plywood Pallets

Material:

1) CARBON STEEL ASTM A105

Surface Antirust:
Surface antirust 1: Antirust light oil
Surface antirust 2: Black paint coating
Surface antirust 3: Yellow paint coating
Surface antirust 4: Galnavized (Hot Dipped Galvanized or Cold Galvanized or Electro Galvanized)

Surface Finish:
Surface finish 1: Stock finish
Surface finish 2: Sprial serrated

Surface finish 4: Smooth finish

Uses of Socket Weld Flanges:

  1. They are ideal for small diameter applications.
  2. They are used for high pressure applications.
  3. Socket Weld Flanges have an internal recess on the inside diameter which allow for a smoot flow of the process fluid.
  4. They create a smooth bore with the proper welding and grinding.
