90/10 Copper-Nickel seamless pipe is a pipe made of 90% copper and 10% nickel alloy. This material combination provides excellent corrosion resistance and good resistance to seawater corrosion. There are no welds or seams in the manufacturing process of this seamless pipe, ensuring the overall uniformity and strength of the pipe.
Due to its excellent corrosion resistance, 90/10 Copper-Nickel pipe is widely used in shipbuilding, marine engineering, oil and gas industries, etc. They are particularly suitable for use in seawater cooling systems, heat exchangers and other applications requiring long-term exposure to the marine environment.
In addition, 90/10 Copper-Nickel pipe also has good anti-bioadhesion properties, which can reduce the adhesion of marine organisms such as shellfish, thereby maintaining the cleanliness and efficiency of the pipeline. This kind of pipe is not only corrosion-resistant, but can also withstand certain mechanical pressure and thermal stress, making it a very reliable and economical choice.
