Flange

Our flanges are manufactured using a forging process to ensure strength and durability. In pipeline systems, flanges serve as essential components for connecting sections of pipe. Based on petrochemical industry standards, flanges can be categorized into various types, including butt weld neck flanges (WN), socket weld flanges (SW), threaded flanges (TH), loose flanges, lap joint flanges (LJ), slip-on flanges (SO), blind flanges (BL), orifice flanges, and spectacle blind flanges
