Cuni 70/30 Welded Pipe and ASTM B466 C71500 Seamless Pipe supplier in India

The answer to what is Copper Nickel 70/30 Pipe is that they are made up of an alloy that consists of 70% copper and 30% nickel. They also have trace amounts of other elements like manganese and iron. Due to the chemical composition, the UNS C71500 Pipe has enhanced resistance to corrosion and they have improved strength level than the 90/10 copper nickel pipes. Because of its features, the Cuni 70/30 Pipe is highly demanded across several industries, and they are used in highly demanding applications. It is to be noticed that the ASTM B466 C71500 material has improved corrosion resistance in water with high velocity as well as polluted seawater.
The 70/30 Copper Nickel Seamless Pipe can be easily cold worked. They come with high fabricability and weldability, without any special or specific material considerations. The seamless pipes are stronger and less prone to leakage than the Cuni 70/30 Welded Pipe, and thus they are used in more critical applications.
One of the popular equivalents of 70/30 copper nickel pipe is DIN 2.0882 Pipe. They are easily customizable and their shape, size, dimension, and surface finish can be modified according to the application requirements. The key features offered by MIL-T-16420K Alloy 715 Seamless Pipe would include excellent corrosion resistance in marine environments, resistance to biofouling, along with enhanced strength and toughness. Due to these properties, products made with 70/30 material are used in industries like marine, offshore, chemical processing, and so on.

What is UNS C71500 Pipe?

UNS C71500 offers superb corrosion resistance, especially in environments that consist of salt water. The Chemical Composition of Cu-ni 70/30 Pipe is Copper, Cu 70.0 and Nickel, Ni 30.0. WERKSTOFF NR. 2.0882 Pipes has a Density of 8.94 g/cm3 (0.323 lb/in3) and its Melting Point is 1171 °C (2140 °F). Cu 70/30 Seamless Pipes has a Machinability (UNS C36000 (free-cutting brass) = 100%) of 20%. 70/30 Cuni Pipe is used in various applications such as sea water pipe work, fish cages for aquaculture, tubes for power plants and ships and in heat exchangers and condensers.
Other designation equivalent materials to Cu-Ni 70/30 Seamless Pipes are ASME SB395, ASTM B171, ASTM B552, DIN 2.0882, ASME SB171, ASTM B466, ASME SB467, MIL T-15005, ASTM B432, MIL T-22214, ASME SB111, ASME SB543, SAE J461, ASTM B608, MIL T-16420, ASTM B151, ASME SB359, ASTM F467, ASME SB466, ASTM B543, ASTM B395, ASTM F468, SAE J463, ASTM B359, ASTM B111, ASTM B552, MIL C-15726 and ASTM B122. Cu-Ni 70/30 ERW Pipes consists of 70% copper and 30% nickel alloy, to which are added manganese and iron.
UNS C71500 Welded Pipe has a Tensile Strength, (ultimate) of 372-517 MPa (54000-75000 psi) and a Tensile Strength, [yield (depending on temper)] of 88.0-483 MPa (12800-70100 psi). 70/30 Cupro Nickel Welded Pipe is seen to be in big demand in desalination units, sea water services, offshore fire water systems, hydraulic lines and in pumps, sea water condensers, valves, salt water pipe fittings, sheathing and fittings for ship hulls, salt water flanges valve bodies and various salt water applications.
