Finding ASTM A182 compliant socket weld flange producers in India? In addition to carbon steel, stainless steel, low alloy, nickel, inconel, copper, hastelloy, aluminium, and titanium, we also produce SWRF flange.


What is socket weld flange?
The socket weld flanges are utilised on smaller-diameter, high-pressure pipelines. The flanges have a hole through which the pipe is placed before having the top of the pipe fillet-welded. This facilitates a smoother bore, which improves the flow of gas or liquid in the run pipe.
The socket weld flanges are available with a variety of faces, including flat, raised, and ring-type joint facing. Depending on the specific needs, their proportions might be altered. There are several material grades for the socket weld flanges, including carbon steel, alloy steel, stainless steel, etc. It's important to keep in mind that this kind of flange isn't regarded as a high-integrity junction. This is due to how difficult it is to demonstrate the weld. Because of this, socket weld flanges are more frequently seen in low to medium classes with ASME ratings of 600 or below. Due to their low integrity and unsustainability to be used at higher pressures, the socket weld flanges mostly have a raised for flat face. It is to be noted that the mechanical strength of the socket weld flanges is quite similar to that of the slip-on flanges, even though the latter uses double welds.
According to the ASME B31.3 standard, there must be a gap of at least 1.5 mm between the pipe and the socket in order to accommodate any thermal expansion that may occur during the welding process. As a result, there are fewer chances of weld cracks.

How do you install a stainless steel socket weld flange?
The pipe must be inserted through the socket all the way to the bottom of the shoulder region in order to install a stainless steel socket weld flange. After that, the connection is completed by fillet welding. Here, making an expansion gap between the pipe and the flange should be the main objective.

Do carbon steel socket weld flange have a schedule?
The pressure classifications for the carbon steel socket weld flanges start at #150 and increase higher. Their schedule ranges from 40 to 160 hours. The ID of the socket weld flange must match the ID of the pipe in accordance with the pipe schedule regulation.

What are Socket Weld Pipe Flanges Face Types
There are different Socket Weld Pipe Flanges Face Types, like:

  1. Raised face- They are easily recognizable as the surface area of the gasket is positioned above the flange’s bolting line. It helps to concentrate the pressure of two mating flanges into one place, so as to provide a tighter seal.
  2. Flat face- Their contact surface is at the same height as that of the flange’s bolting line.
  3. Ring Type Joint facing- It offers metal to metal sealing between the mating flanges. IIt is perfect for high temperature and high pressure applications.
  4. Lap Joint- It comes with a flat face that helps to host the back of the stub end. The sealing surface can either have a flat or raised face.
  5. Tongue and Groove- A pair of tongue and groove flanges fit with each other perfectly. They can be mated easily, and are available in big and small types.

Advantages and Disadvantages of Flat Face Socket Weld Flange
Socket welding with a flat face The whole surface of the flange mating region is in full contact with the gasket when using a flange. In essence, it aids in preventing any bending moments placed on the flange during bolt torque. They are mainly employed in less crucial applications, such as those that require low pressure and low temperature.
However, it's crucial to keep in mind that flat face flanges can't guarantee a secure connection like raised face flanges can, therefore they should only be used in less crucial circumstances.

RF Type

RF Type: A little part of the RF socket weld flange protrudes from the face and surrounds the flange bore. In this raised location, a gasket seat will be installed.

RTJ Type

RTJ Type: There is an RTJ style groove on the raised face surface where you can add a gasket ring to improve sealing performance.

Pull the inserted pipe back 1.6mm (1/16") and fillet weld after inserting the pipe end into the socket weld flange until the pipe bottom touches the shoulder area. To create an expanding gap between the flange and the pipes or fittings is the objective (1 fillet weld).
