About Socket weld flanges SWRF flanges
The second most type of fitting used to join piping equipment is flanges. They can also be exercised in dismantling. It offers maintenance flexibility. Flanges connect equipment and valves. They are added in the mainline system during plant operation if maintained regularly.
They got connected to pipes using single fillet on the outer side. They are first inserted into the socket of the flange and lifted and welded at last. The gap is lifted for proper positioning after solidification of the weld. It is mainly exercised for high-pressure and small-size piping that don’t deliver corrosive fluids.
The joint is composed of 3 independent and separate components namely, the gaskets, the flanges, and then bolting. Special control in application and selection of elements is considered to attain desired joint type with acceptable leak tightness. However, it is recommended not to use in undergrounding piping system. Thus mostly used in fire and leak process plant. Plenty of flange types are in the market depending on the connection, facing type, pressure-temperature rating, and material type.
Common types are threaded flanges, socket weld flanges, slip-on flanges, and lap joint flanges. Out of all, the socket weld flanges SWRF flanges are mostly used.
