Flanges

We manufacture export quality flanges in all desired standards. All of are flanges are manufactured taking in to account customers pressure and application requirement. Flanges are custom built to suit the clients specification the best . Our flanges are also used in industry where pipe lines require high pressure flanges and we use quality SS grade materials for our flanges in highly corrosive areas thus ensuring durability in long run. Whether it be Blind, Threaded, Weldneck, Socketweld, Slipon, Lapjoint or orifice, We have sizes ranging from ½” to 48”. Classes like ASA 150 to 2500, BS Table E to K, DIN from ND6 to ND64 and Grades like A105, A304L, A181, A350-LF2, A181-F1, F5, F9, F11, F22 etc. Like ASA 150 to 2500, BS Table E to K, DIN from ND6 to ND64 and Grades like A105, A304L, A181, A350-LF2, A181-F1, F5, F9, F11, F22 etc.
