Copper Nickel (CuNi) alloys are famous for its excellent resistance to seawater corrosion and biofouling. To make it even more ductile and optimise the alloy\’s corrosion resistance in seawater, a few amount of iron and manganese are often added to CuNi alloys. Given these qualities, CuNi alloys are widely used in several marine applications such as offshore fire water system, heat exchangers and condensers, hydraulic lines, sheathing of legs and risers on offshore platforms desalination units, and many more.
These metal alloys are also used in building piping systems that are exposed to harsh conditions. It took years of careful study and research before this alloy became the standard material for the marine building industry. Those who work in the field of marine engineering and ship building are expected to be familiar with these set of standards.
When CuNi was first developed during the 1920s the alloy was composed of 70% copper and 30% nickel. A few years after, researchers and engineers added 2% manganese and 2% iron to the mixture. This combination allows for an alloy that is more resistant to corrosion, which is great for making piping systems that are submerged under water. Today, these two types of alloys are widely used in the industry. The 70/30 CuNi alloy is more resistant to corrosion, while the 90/10 is more affordable and can be used in most marine applications.
In order to optimise its full potential, a great amount of thought should be given to the composition of alloys. Each composition should be in accordance with the world standard. For instance, the alloy must not be exposed to pollution. Limitations in terms of velocity and turbulence were also placed to to ensure that the piping systems will perform to its fullest and promote safety.
This alloy can only be made by people who the right knowledge, skills, and experience in this field. If you use Copper nickel in your endeavours, you can look for a marine engineering company. They will not only answer for your material requirements but they\’ll also help fulfil your needs for piping systems. Hiring professionals for fabrication and pipe laying installations will not only save you money, but it will also bring you security and peace of mind.
