Nickel Alloy Tubing

Nickel-based alloys are very useful materials for the manufacture of high-quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high-temperature applications.

In addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. They can be electroplated and are easily welded, making them suitable for use in industries where very high and low temperatures come into play.

Nickel-based alloys have a higher ability to accept alloying elements in solid solutions than other stainless steel or iron-based alloys. They can therefore maintain higher metallurgical stability. The combination of high alloying with multiple elements can provide very good corrosion resistance in a wide range of environments while still maintaining good welding and forming characteristics.

Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industries. They’re used in steam generator tubing in the nuclear power industry, in high-temperature aircraft systems, and in oil and gas extraction programs where corrosion-, pressure- and temperature-resistant tubing is required. Their corrosion resistance also makes them useful in desalination equipment.
