Inconel Long Butt Weld Flanges have a hub that extends out of the flange plane, making it easier to accommodate pipes. These flanges are made of alloys of nickel, chromium and molybdenum with other elements. This long weld neck flange alloy offers increased toughness, durability and general corrosion resistance compared to other flange grades. Long neck butt weld flanges have an extended neck welded to the flange. The extended neck guides the pipe into the flange and has additional mounting and gripping surfaces. This type of flange provides additional reinforcement for the connection.
