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. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". Bangdong provides Socket Weld pipe flanges in all material grades, specifications and sizes.

Socket Weld pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for socket weld pipe flanges, the standard height is 1/16" for socket weld pipe flanges under 400#. For socket weld pipe flanges of 400# and up, the standard socket weld pipe flange raised face height is 1/4".

Bangdong manufactures socket weld pipe flanges in all steel material grades, including carbon socket weld pipe flanges, stainless steel socket weld pipe flanges and alloy socket weld pipe flanges. Bangdong also has many different socket weld pipe flanges in stock and ready to ship.

Socket-Weld Flanges has a female socket in which pipe is fitted. Fillet welding is done from outside on the pipe.

The socket welding flange is similar to a slip-on flange except it has a bore and a counterbore dimension.

The counterbore is slightly larger than the O.D. of the matching pipe, allowing the pipe to be inserted into the flange similar to a slip-on flange.

The diamter of the smaller bore is the same as the I.D. of the matchine pipe A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on.

Standards, Dimensions & Weight
Socket Welding Flanges, SW FlangeThe Socket Welding Flange is attached to the pipe by a fillet weld around the hub of the flange. An optional internal weld may be applied in high stress applications.
  • ASME/ANSI B16.5 Class 150 SW
  • ASME/ANSI B16.5 Class 300 SW
  • ASME/ANSI B16.5 Class 600 SW
  • ASME/ANSI B16.5 Class 1500 SW
This is eliminates any restriction in flow when using a socket welding flange.
Specifications of Socket Welding Flanges:

This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).

Advantages and disadvantages of Socket Weld fittings

The pipe need not be beveled for weld preparation. Temporary tack welding is no needed for alignment, because in principle the fitting ensures proper alignment.
The weld metal can not penetrate into the bore of the pipe.
They can be used in place of Threaded Fittings, so the risk of leakage is much smaller. Radiography is not practical on the fillet weld; therefore correct fitting and welding is crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods.
Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation.
