CuNi 90/10 Forged Fittings and Copper Nickel Threaded Pipe Fittings manufacturer in India

copper nickel socket weld fittings

If you are wondering what is Copper Nickel Socket Weld Fittings, then it is basically made up of an alloy which consists of copper and nickel. There are several other alloying elements present in it as well, including manganese and iron. The Copper Nickel Threaded Pipe Fittings are used by several industries for their cooling units. Generally these units are found in the desalination plants and power generation plants. They use seawater in the units that have Copper Nickel Forged Fittings to make sure that their devices remain below a certain high temperature. The salinity and the seawater corrosion caused by the saline water is tackled efficiently by the Copper Nickel 90/10 Socket Weld Fittings and pipes used in these units. The material is widely known for its power to resist seawater corrosion.

The Copper Nickel 90/10 Threaded Pipe Fittings and pipes are available in customizable shape, size and dimensions, as per the specific application requirements. They are also available in different grades, like Copper Nickel 90/10 Forged Fittings, or 70/30 fittings, etc., and each of them has slightly varying physical properties according to their chemical composition.

The Cuni 70/30 Socket Weld Fittings are a popular grade for various marine, architectural, and industrial applications. They have a high toughness and are known for their ductility. The UNS C70600 Coupling also possesses high resistance to oxidation and good health, even at elevated temperatures. The Cuni 90/10 Union can be fabricated by both hot and cold working procedures and they are readily weldable too. This means that the material can be welded to Copper Nickel Plug and other forms, using standard welding procedures. The material is available in different forms, such as CuNi10Fe1Mn Tee, unions, caps, and other types of fittings.

The CuNi30Mn1Fe Cap is used in a wide range of applications like off-shore oil drilling applications, gas processing, pharmaceuticals, seawater equipment, petrochemicals, etc. The C7060X Bushing shows good performance at high temperature, which includes, heat exchangers, condensers, speciality chemicals, etc. The Cuni 70/30 Hex Nipple comes with a high leakage integrity and they also have good structural strength, which is why they are used for a wide range of applications.

Copper Nickel Forged Fittings is called cupronickel, it is also called Cu-Ni Threaded Pipe Fittings. This is an alloy that consists of copper, as well as nickel and it also has present in it, strengthening elements like manganese and iron. Copper Nickel socket weld fittings has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). The Elongation at Break of Copper Nickel Fuel Fittings (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%.

Copper Nickel Threaded Union are used by a large number of industries in their cooling units. These cooling units are present in their power generation plants and in their desalination plants. But these desalination plants and power generation plants, make use of seawater, to ensure that their devices remain cool. But, the big problem here is the salinity in the seawater. It results in the corrosion of the pipelines. To counter this, these industries make use of Copper Nickel Threaded Fittings that are made from copper nickel, as they are highly resistant to corrosion from seawater. Socket Weld Union corrosion resistance is offered by copper nickel and as such it is highly resistant to corrosion in seawater. The Yield Strength (annealed) of Copper Nickel Forged Union is 15000 psi (103 MPa). The Molecular Formula of Copper nickel Coupling is ‎CuNi. The Machinability of Copper-Nickel Machined Fittings (based on free-cutting brass = 100) is 20. Cuni forged fittings are in big demand in the power generation industry and in the ship building industry, because of their high resistance to salt water.
