Socket Welding Flanges, SW Flange

Socket Weld Pipe Fitting,Socket-Weld Flanges is type of  Forged Steel Pipe Fitting, 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.

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.

Forged steel Flange are perfectly finished with precision using the latest machinery.

Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.
Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

                                      Forged stainless steel flange

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard. Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.

The flanges are suitable for connection of steel pipes conveying mediums such as steam, oil, air and water. They are widely used in Chemical industry and Shipbuilding . And the flanges are suitable for welding.The flanges mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket,Reducing and Plate type.

Size available: 1/2"--72"(DN15-DN1800).

Forged steel flanges are made in seven primary ratings:

Asme B 16.5 Class 150 lb 400 lb 900lb 2500lb 300lb 600lb 1500lbcutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.
