COPPER NICKEL PIPE FITTINGS MANUFACTURER IN INDIA

Cuni Stub End, Reducer and Cupro Nickel Fittings manufacturer as per ASME B16.9/ B16.25

copper nickel pipe fittings

A copper nickel pipe fitting is a moderate strength grade that plays an important role in characterizing the flow of media. Copper Nickel Pipe Fittings are employed to join dissimilar size items, route, and branch connections. These fittings are designed with primary constituents of nickel, copper, and ferrous with other constituting alloys. The Cupro Nickel Fittings have good corrosion resistance properties and work well in marine environments. The versatile fittings thereby have enhanced tolerance to pitting and crevice corrosion. Cuni Pipe Fittings have a crystalline structure and have lower internal stress. These fittings have excellent mechanical and physical properties. The ASME B16.9 Cuni Fittings are factory-made wrought fittings that are available in different dimensions to suit several project requirements. Cupro Nickel Pipe Fittings have lower macrofouling rates and possess good fabricability. These fittings are designed in either seamless or welded configurations. The Cupro Nickel Seamless Fittings are a single piece of metal that is produced via an extrusion process. The absence of welds allows for an even flow in the system. Cupro Nickel Welded Fittings are a reliable cost-effective alternative to seamless fittings that is produced as metal is rolled and subsequently welded in place. The Cunifer Buttweld Fittings are common welded fittings that are seen widely across different industries. These fittings can handle fluids and gases of a wide range of pressures or temperatures. We are a Copper Nickel Pipe Fittings manufacturer in India who have a vast stock of products of different sizes and shapes.

The Copper Nickel Tee is a common fitting that has three channels of which two are outlets, and one is an inlet. They can be availed in  either equal or reducing sizes. A Cupro Nickel Reducer is employed to reduce the size of large-bore size to a smaller one. These reducers ensure that there is no failure in the system due to uneven flow conditions. Cupro Nickel Cap seals the ends of the hydraulic system and prevents any natural contaminants from entering the grade. A Copper Nickel Collar is an adapter that helps connect one pipe to a system without requiring to punch or drill holes in the item. The Copper Nickel Stub End is a short piece of a pipe that is flared on one side, with the other one exhibiting a square-cut end. The Cupro Nickel Saddles are devices that support and transfer a load of pipe onto the support base. This prevents any vibration or bouncing. Sunflex Metal is a Copper Nickel Fittings manufacturer in India that utilize the best raw materials and cutting-edge technology to produce all our products.

Sunflex Metal has been formed in 1990 as a Copper Nickel Pipe Fittings manufacturers in India and since then has developed its strong 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. Sunflex Metals stock a wide range of butt-weld fittings that conform to ANSI and military standards. We carry Copper Nickel Tee, Saddles, Reducer etc in Class 200 and Class 700 for high pressure.

WHAT IS CUPRO NICKEL FITTINGS?

The Tensile Strength of Cupro Nickel Fittings (rolled-H04 for flat products/ hard drawn-H80 for tubing) is 78000 psi (538 MPa). These Cuni 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.
