A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. There are various types of flanges being manufactured, export, and supply by the Fitwell India. But few specific types of flanges we do export in the domestic and international markets. The key types of flanges are the weld neck (WNRF), long welding neck, slip-on(SORF), socket weld(SWRF), lap joint, screwed(SERF), Weld Neck Ring Joint(WNRTJ) and blind(BLRF) flanges, In addition to these standard flanges, some special ones exist, called Weldoflange/Nipoflange and Elbow Flange, swivel flange, expander/reducer flange, and orifice flanges.
We also do manufacture, supply and export different material grade based flanges such as stainless steel flanges, carbon steel flanges, steel alloy flanges, nickel alloy flanges, inconel flanges, monel flanges, hastelloy flanges, cupro-nickel flanges, titanium flanges, duplex flanges, super duplex flanges.
