Copper and Copper-Nickel Fittings[INQ. NO. 1910M03] Seamless butt weld fittings are produced from seamless tubes and pipes either by hot or cold extrusion, forming, forging, machining, or by a combination of two or more of these operations.
Seam-welded butt weld fittings are produced from hot or cold rolled, annealed or pickled sheet or plate, formed into half shells or segments and longitudinally seam-welded.

Copper and Copper-Nickel Flanges

Composite weld-neck and composite slip-on flanges are formed from components, an inner flange (welding collar) in Cu-Ni 90/10 or Cu-Ni 70/30 and an outer flange in carbon steel. Composite blind flanges are produced from a carbon steel blind flange welded with a machined disc in Cu-Ni 90/10 or Cu-Ni 70/30.
Solid flanges in Cu-Ni 90/10 or Cu-Ni 70/30 are produced from bar or plate by hot forging and machining. The use of solid silver brazing flanges in corporate integral silver brazing alloy rings means that under normal circumstances there is generally no need for socket feed with additional brazing alloy.
