As the name suggests, cuni fittings or Copper-Nickel fittings are made using an alloy of Copper and Nickel. These fittings are known for their use in underwater and marine applications. This is because they have strong general resistance to corrosion that usually occurs due to seawater. Due to the high concentration of Copper and Nickel, cuni fittings are extensively used in the power plants and the shipbuilding industry for connecting pipes.
Copper is very well known for its high electrical conductivity, high ductility, high heat conduction, good machinability, and corrosion resistance. This makes it one of the most widely used materials in the industrial space.
Nickel, on the other hand, possesses better corrosion resistance, greater toughness, and strength at both high and low temperatures. Though it is not normally used as a stand alone material in the industries, it can be combined effectively with another material to form an alloy.
Benefits of cuni fittings
Some of the common benefits offered by these Copper Nickel fittings are:
- High resistance to corrosion in seawater.
- High resistance to SCC ( Stress Corrosion Cracking ) underwater.
- High resistance to pittance and corrosion due to chlorides
- High resistance to pitting
- Easy to weld and fabricate
Besides these, Copper-Nickel fittings are extensively used in areas requiring high tensile strength. This ensures that the pipes can endure the high temperatures which might otherwise create residual stresses and strains. Thus enabling them to work under high pressures without showing any signs of fatigue.
Types Of Copper Nickel Fittings
Copper Nickel fittings can be used in various forms, some of which are:
- 90-degree elbows
- 45-degree elbows
- Forged tees
- Forged cross
- Forged plug
- Street Elbows
- Pipe Nipples
Generally, all the Copper-Nickel fittings can be forged as per the demand of the customer and can be made to suit the requirements. These can also be ordered in various size ranges so that you can utilize the fittings at various parts of the plants. They are designed to withstand different levels of pressure such as 2000 lbs, 3000 lbs, 6000 lbs, 9000 lbs, etc.
Since these fittings are ultimately to be used in pipelines, it is important to know the type and size of the pipes in which they are to be used. Hence, the type of pipes plays an important role in the final decision of buying the fittings.
