MSI Fittings has been formed in 1990 as a Copper Nickel Pipe Fittings manufacturers in India and since then has developed its b reputation in supplying the right ASME B16.9 Copper Nickel Fittings. Ask for our Copper Nickel Pipe Fittings catalogue can help you to choose the ideal thing when seeking all kinds of Cuni pipe fittings made in India. This catalogue will cover specifications, weights and sizes of the Cupro Nickel Fitting that are available. The Machinability of Cuni Fittings (based on free-cutting brass = 100) is 20. MSI Fittings stock a wide range of butt-weld fittings that conform to ANSI and military standards. We carry Copper Nickel Tee, Copper Nickel Reducer etc in Class 200 and Class 700. for high pressure.

The Tensile Strength of Copper Nickel Fitting (rolled-H04 for flat products/ hard drawn-H80 for tubing) is 78000 psi (538 MPa). Copper Nickel EEMUA 146 Pipe Fittings has a Tensile Strength (annealed) of 52000 psi (359 MPa). Copper-Nickel Pipe Fittings are used in various application areas such as pipelines in shipbuilding, oil coolers, electrical resistors, steam turbine condensers, sprung contacts in relays, plug connectors and switches, auxiliary cooling systems and in a large number of cryogenic applications. The Chemical Composition of Copper Nickel Pipe Bend is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. The Molecular Formula of Copper nickel is ‎CuNi. Wall thickness chart help to select the various specifications and thickness of the various types of Cupro Nickel Long Stub that are available. The Thermal Expansion Co-efficient of Copper Nickel Pipe Fittings (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). ANSI B16.9 Cu-Ni Welded Buttweld Fittings has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). Cupro Nickel 5D Bend are also used in conveying brackish water, clean seawaters and fresh water. Copper Nickel Bellmouth Fittings are also used in fasteners, boat hulls and in heat exchangers. Such Cuni Pipe Fittings also find use in high pressure pre-heaters at fossil fuel power plants and nuclear power plants and Copper Nickel Fuel Pipe Fittings for fuel systems.
