Nickel alloy Pipe fittings used in piping systems to connect straight sections of pipe, to adapt different sizes or shapes, and for other purposes. consists alloys with nickel as principal element. Complete solid resolvability exists between nickel and copper. This wide resolvability ranges between iron, chromium, and nickel which make it possible many alloy combinations. nickel alloy forged fittings is also useful in cryogenic temperatures because of its very low thermal expansion rates. It has more fine and softer looking finish and has a slightly brushed appearance with a semi satin finish. brushed nickel fittings are thicker, heavier and are intended for heavy industrial use.
Nickel Fittings this is available in grade such as Nickel 200 (UNS N02200), Nickel 201 (UNS N02201).A pipe fitting which installed between two lengths of pipe to allow a change of direction, usually at 90° or 45° angle. include union, elbow, couplings, bends, tees, reducer, caps, nipple, stub ends, etc. It is used in diverse industries for pipe connection, assembly of machines, auto mobiles parts, it is very resistant to corrosion and oxidation and when heated form a thick, stable, passivating oxide layer which protect from further attack
