Inconel 718 Pipe Fittings

Besides two conventional forging processes of Inconel 718 Double Ferrule Pipe Fittings, including forging driven by hydraulic presses or hammers, and some advanced forging processes, such as hot die forging, insulation die forging and isothermal forging, have been developed to manufacture fine grains forgings. High tolerance to extremely high and low temperatures allows these Alloy 718 Compression Fittings to be welded and annealed into products that will withstand extreme conditions.
