Purohit Pipe Industries exports and distributes CS Socket Weld Fittings with excellent impact strength. The same is also available in different grades and specifications, including ASTM A234 Carbon Steel Forged Socket Weld Fittings, ASTM A105 Carbon Steel Forged Socket Weld Fittings, and ASTM A106 Gr. B Carbon Steel Forged Socket Weld Fittings. In addition to process, seawater, firewater, and subsea pipework systems, socket weld pipe fittings are commonly used as risers, manifolds, pressure vessels, valves, and heat exchangers in oil and gas applications. Other industries that use socket weld pipe fittings include pollution control equipment such as flue gas desulfurization equipment (FGD), pulp and paper, power generation, chemical, pharmaceutical, desalination, mining, metallurgical and marine. Forged Carbon Steel Socket Weld Cap Fittings do not undergo a true ductile-brittle transition, just a gradual decrease in impact energy with lowering temperature. Carbon Steel Forged Socket Coupling Fittings have varying impact energies depending on the type and production process. Carbon Steel Forged Socket Weld Cross Fittings have a slightly lower impact strength than their parent metal counterparts.. A suitable acceptance criterion for Carbon Steel Forged Socket Weld Union Fittings is that it can be achieved with all product forms down to very low temperatures. In Carbon Steel Forged Socket Weld Plug Fittings, copper is added to enhance their resistance to sulfuric acid.

Depending on the pipe diameters and orientations allowed by socket weld fittings, wide pipes can be joined to narrower ones, and a pipe network can have branches or change directions. Listed below are various coupling thread arrangements for socket weld fittings:
Using this socket, two pipes can be connected together, with threads at both ends.
With half couplings, the non-threaded end is usually welded or fastened to piping in a similar way to full couplings.
Using different width sockets at either end, these fittings connect two pipes of different diameters.
Socket Weld Reducer Insert
It is also possible to connect pipes with different diameters with this reducing fitting.
Socket Weld Union
Three-part fittings with two internal threads each side of an interconnected centrepiece bring pipe ends closer together by rotating the centrepiece. In order to minimise seat warping, the socket weld union must be tightly screwed before welding the ends.
Socket Weld Elbow
The SW elbows can be either short radius or long radius designs depending on the application. They are available at 90 degree and 45 degree angles.
Socket Weld Tee
In a socket weld tee fitting, a 90-degree branch can be created from a straight pipe, or a smaller diameter pipe can be used to create the same T-junction.
It is similar to the threadolet and weldolet in that it can be used to join smaller diameter pipes to larger ones. The sockolet includes a socket in the olet (hence the name), which makes welding convenient. Besides its ability to create a 90 degree direction change, the sockolet is able to withstand high pressures as well.
Socket Weld Cross
With this cross-formation fitting, two branches traveling in the same direction can change direction by 90 degrees.
A socket weld cap seals the end of a pipe.
There is a recessed shoulder on the inner diameter of socket weld flanges that allows the pipe to be fitted correctly. There is a recessed shoulder on the inner diameter of socket weld flanges that allows the pipe to be fitted correctly.l diameter pipes and can work at higher pressures, offering excellent.
Advantages of Socket Weld Fittings
There are several inherent advantages to socket weld fittings for joining pipes, including:
- To align the pipes for welding, the socket is easy to use, eliminating the need for tack welds
- Fittings with socket welds are less likely to leak than those with threads
- Socket design prevents weld metal from flowing into pipe bores
- The more relaxed dimensional requirements of socket weld fittings make them cheaper to install than butt weld fittings. Because socket weld fittings do not require special machining, they are cheaper to install.
What is the Difference between Socket Welds Pipe Fittings and Butt Welds Pipe Fittings?
Because socket welds and butt welds have different welding specifications (ASME B16.11 for socket welds and ASME B16.9 for butt welds), they are governed by different standards.
The pipe is inserted into a recess at the joint, and no beveling of the pipe ends or preparation of the materials is required.
The fittings must be the same thickness as the pipes in order to be butt welded. However, the joints must also be beveled at the ends in order to be butt welded.
Besides these practical differences, butt weld fittings tend to be stronger, so socket weld fittings are usually reserved for pipes with relatively small diameters, Besides these practical differences, butt weld fittings tend to be stronger, so socket weld fittings are usually reserved for pipes with relatively small diameters.
Why to use Socket Weld Fittings?
Fittings with socket welds join small diameter pipes used to convey flammable, toxic, or expensive materials that cannot leak. Fittings with socket welds can also be used for steam with a pressure of 300-600 psi. By using these connectors, a strong union can be created with a high flow characteristic and a reduced chance of leaks.
How Socket Welding Works
Socket welding refers to the fittings into which pipes are welded. Pipes are inserted into recessed sockets before they are welded into place in these fittings.
Pipes should be inserted into sockets with a gap between the end of the pipe and the bottom of the socket. When the heat from the welding process expands the pipes against the socket, this gap prevents a stress failure. To ensure the pipe doesn’t bottom out into the socket, a permanent fitment tool can be inserted into the fitting and used to measure and mark the gap. Upon placement, the pipe is fixed in place by fillet welding at the join between the pipe and socket.
Using socket welds, liquids or gases can be transported in sealed, leak-proof, high-pressure pipelines. The pipe ends should be clean to ensure the integrity of the weld, but socket welds do not require any pre-weld machining.
Socket Weld Inspection
In addition to visual inspection, other non-destructive testing methods can also be used to assess socket welds.
A magnetic particle inspection can be used to locate surface and near-surface defects in pipe welds, while a radiographic inspection can locate internal defects.
How do you fit a Socket Weld?
In order to fit a socket weld, a pipe is inserted into the fitting’s recess, with a gap of at least 1/16″ to allow for pipe thermal expansion under welding pressure. Using a series of fillet-type welds, the pipe can be welded in place. The thermal expansion gap prevents the weld from cracking if the pipe expands against the fitting.
