Benefits of Socket Weld Flange

Strong and reliable seal
Firstly fitted weld is used to make connections between socket bore and pipe. This joint is strong and reliable enough to withstand severe pressure and vibrations conditions produced at the area.

Compact design
Socket weld flange has a smaller design as compared with other types available in the market. Hence, this compact design is useful for installation in constrained space in industries.

Clean aesthetics
The socket weld after installation provides a smooth connecting surface between flange and pipe. Hence, it reduces the chances of contamination from the outer environment to fluid or gas flowing via pipe. This ultimately also makes the aesthetic pleasant appearance of the system in industries.
Application of Socket Weld Flange
Petrochemical industry
Along with petrochemical socket weld flanges are used in chemical processing plants, refineries etc. These industries have the need to transport hazardous and noxious substances which need reliable sealing of the system. Hence, Socket weld flanges are frequently used to achieve integrity in connecting pipe and flange.
Power generation plants
Power generation plants need to connect systems in steam lines, turbines and boiler systems. All of these areas are superheated and have high pressure. Socket weld flanges are installed here which can withstand such arduous conditions also.
Water treatment industries
Water treatment needs use of many different chemicals and more. All of this needs corrosive resistance material to withstand adverse environmental circumstances. Again, socket weld is chosen here as it is able to withstand all such conditions giving a sturdy seal.
Installation Steps Of Socket Welding Flange
Prepare the pipe
Clean the pipe and ensure to remove all the debris and burrs. After this, cut this for required length according to the particular area.
Prepare the flange
Surface of the flange and socket needs proper cleaning to enable proper fit and sealing. This will increase the longevity and reliability of connection.
Fit the pipe into flange
Insert and push the pipe into the socket of flange till it strikes the bottom surface. Check alignment of the pipe before moving further.
Tack weld
Weld the pipe with a flange around the circumference at different points. These points will help to hold the pipe in place to ensure proper final welding.
Weld the flange
Make a continuous weld around the joining portion of socket flange and pipe. This will ensure a dependable seal which is proven leak proof.
Inspect the weld
Once you finish up with welding, again inspect the weld to look for any irregularities or defects.
Post weld treatment
Sometimes you might need to add post weld treatments like surface finishing or stress relieving on juncture of pipe and flange. But the selection of this treatment depends upon material and application of flange pipes.
Testing
Perform the pressure or leak test to ensure the integrity of the seal with socket weld flange.
