Solitaire Overseas is a trusted manufacturer, exporter, supplier, and stockist of Copper Nickel Pipes, known for their exceptional corrosion resistance, strength, and machinability. These pipes, made from copper-nickel alloys, are especially well-suited for marine applications due to their durability and ability to withstand harsh seawater conditions. They are also ideal for cryogenic applications because of their high performance in low-temperature environments.
Copper Nickel Pipes are available in various types, including seamless and welded forms, and are offered in multiple specifications to meet diverse requirements. Common grades like Copper Nickel 90/10 Pipes and Tubes are widely used in seawater systems, heat exchangers, hydraulic lines, and marine oil and gas applications. Additionally, these products are found in evaporators, chillers, and industrial heat exchangers.
Cupro nickel, also known as copper-nickel alloy, combines copper with nickel and other strengthening elements. Despite its high copper content, the alloy has a silvery appearance. Its excellent resistance to seawater corrosion and other environmental factors makes it highly sought after for marine and industrial applications, driving the demand for products like Cupro Nickel Pipes across various sectors.
With the inclusion of the proportionate amount of iron and manganese inhibits superior resistance to generalized corrosive media and stress cracking properties. In accordance with the inclusion of nickel-copper alloys their certain properties makes it best suited for working in marine or turbulent water applications.
For high fabricability, high resistance to oxidation in a moist atmosphere has become high in demand. Also, it has good thermal stability in addition to moderate strength with high resistance to SSC. With regards to several product quality standards, the product to the esteemed patrons is supplied at different specifications. The Cupro Nickel Pipes can be collected at specified wall thickness, sizes, length etc as per buyer’s demands. To the esteemed patrons, the product is supplied at market leading rates.
