The Benefits of Cupro Nickel 90-10 Seamless Pipe
Whether you are looking for a seamless pipe for your construction project or just a simple piece of equipment, there are many factors to consider when selecting a pipe material. For example, you need to know how the material is made, what applications it's used for, and what its packaging and mechanical properties are.
Applications
Initially, 90-10 copper-nickel alloys were used in naval condensers. Today, these pipes are widely used in seawater piping and heat transfer applications. They are renowned for their excellent resistance to corrosion and biofouling in seawater. They also exhibit excellent welding properties.
The applications of Cupro Nickel 90/10 Seamless Pipe include thermal and sanitary desalination, marine condensers, seawater piping, evaporator tubes, and heat exchangers. These pipes also offer good resistance to hydrogen embrittlement. In addition, they display excellent corrosion and biofouling resistance in brackish water. They are highly resistant to stress corrosion cracking. In addition to its corrosion and biofouling resistance, this alloy offers high flexibility. Its resistance to hydrogen embrittlement is instrumental in seawater. It is also a good choice for heat exchangers and pumps.
Corrosion resistance
Developed for applications in the marine industry, 90-10 copper-nickel alloy is one of the most common alloys for seawater applications. It provides excellent corrosion resistance in salt, high-speed, and polluted waters. In addition to its corrosion resistance, this alloy also offers flexibility and stress resistance. It is also resistant to hydrogen embrittlement. Aside from its corrosion resistance, the material is also highly suited for cryogenic temperatures. This metal's superior machinability, strength, and corrosion resistance make it a suitable choice for various industrial and marine applications. In particular, its antimicrobial properties are particularly useful in healthcare environments. It is also ideal for brake tubing. Besides, it can withstand temperatures up to 760 degrees Celsius. In the chemical processing industry, it is also used for evaporator and distiller tubes.
Resistance to biofouling in brackish water and seawater
Among the many alloys available for marine applications, Cupro Nickel 90-10 Seamless Pipe displays excellent welding properties and excellent resistance to corrosion, erosion, and stress corrosion. Suitable for hygienic environments, it is also known to be immune to chloride stress corrosion cracking.
When exposed to open seawater, a protective surface film forms naturally. This thin film is made of cuprous oxide and iron oxide. Although this film's presence was initially considered insufficient to prevent fouling, it proved effective in providing a sterile surface. The protective film can be wiped away or brushed to remove microfouling. However, the surface film must be free from cathodic protection or other corrosive agents to ensure its integrity.
