We offer immediate delivery programs for standard size of carbon steel Socket Weld Flanges and stainless steel socket weld flanges. Socket welding flanges manufactured in special stainless steel grades, nickel alloy and alloy steel can be supplied with just in time programs from stock.Socket weld flange is similar to the slip-on flange in outline, but the bore is counter-bored to accept pipe. Socket welding pipe flanges are typically used on smaller sizes of high pressure pipes. Socket weld flanges are widely used in high pressure systems such as hydraulic equipment and steam lines. Socket weld pipe flanges are attached by inserting the pipe into the socket end and then applying fillet weld around the hub of the flange. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. An optional internal weld may be applied in high stress applications.

Being a renowned organization, we are offering a huge spectrum of Socket Weld Flanges. The offered weld flange is high pressure systems such as hydraulic equipment and steam lines. This weld flange is manufactured as per the set industry norms using superior quality material. The provided weld flange is examined on several quality parameters for delivering a defect free range.

  • Corrosion-resistance
  • Highly durable
  • Optimum strength

Other Details:
  • The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid
  • Socket welding flanges work well for smaller sizes and higher pressure temperature conditions
  • They are similar to slip-on flanges, but must specify the schedule of the pipe where they will be used for with socket welds
  • welded both inside and out to provide sufficient strength and prevent leakage
  • They are ideal for low pressure applications

  • They are ideal for small diameter applications
  • They are used for high pressure applications
  • Socket weld flanges have an internal recess on the inside diameter which allow for a smoot flow of the process fluid
  • They create a smooth bore with the proper welding and grinding.Flange dimensions to ANSI B16.5. Dimensions "B" & "D" includes raised face thickness
  • Bore (SCH) "C" purchasess to Specity
  • Larger outlet sizes are avilable on applications
  • ANSI 150# / 300# 2mm Raised Face
  • ANSI 600# / 2500# 7mm Raised Face
