Copper Nickel 70/30 Pipe Fittings

If you want to know What is Copper Nickel 70/30 Pipe Fittings, then here is the answer. It is a pipe fitting made up of an alloy that contains 70% copper, 30% nickel, and trace amounts of other elements like manganese and iron, in its chemical composition. Due to the chemical properties of the UNS C71500 Fittings, they have enhanced strength and corrosion resistance. The 70/30 Copper Nickel Pipe Fittings possess several properties, which is why they are popular across different industries. 

Some features of the CuNi 70/30 Stub End would include good mechanical strength and rugged construction. They also have high toughness and can resist erosion effectively. The Copper Nickel 70/30 Tee is also known for possessing high tensile strength and can effectively resist pitting and oxidation. They also resist cracking due to stress corrosion and crevice corrosion. The 7030 Copper Nickel End Cap shows good high temperature performance and is quite long lasting too. They are well-known for their durability. It is to be noted that the corrosion resisting capabilities of the ASTM B466 UNS C71500 material is improved when there is high velocity water or polluted seawater. The UNS C71500 Reducer is basically cold worked and they come with high weldability and fabricability.

Due to all these properties of the CuNi 70/30 Saddle, they are highly demanded across several industries. The antifouling property of the Cupro Nickel 70/30 Equal Tee makes it perfect for seawater environments. The DIN 2.0882 Tee Fittings creates a thin layer of a protective film which does not allow marine life to grow on the pipe walls. This is why the 7030 Cupro Nickel End Caps are used in different business sectors.

The 70 30 Nickel Copper Alloy Stub End shows moderate performance at elevated temperatures. They are thermally stable and the 70/30 Cu Concentric Reducers show good performance when it comes to corrosion resistance. It does not get affected by seawater and that is why the CW354H Reducing Tee is preferred for various seawater equipment.

As the CuNi30mn1fe Pipe Fittings have high fabricability and hence they can be fabricated using standard procedures. They can also be welded without any special considerations. The Cunifer 70/30 Buttweld Fittings can resist high temperature situations and hence they are used in various drilling type equipment, which are primarily used for extracting marine life from deep within the sea.
