The use of Nickel alloy pipe in different industries


Blog / Tuesday, October 15th, 2019

Nickel, in elementary form, as well as when alloyed with other metals, has made significant contributions to our society. It is a versatile element and can be alloyed with most of the metals. Nickel alloyed products are used in various industrial applications due to excellent physical properties. This post discusses the physical properties and applications of nickel alloys.

Physical Properties of Nickel Alloys

The physical properties of Nickel alloys are as follows-

1. Heat-Resistant: Nickel alloys are majorly used in applications, where they are exposed to high temperatures. Nickel-Chromium alloys are used to offer both carburization resistance and oxidation at temperatures beyond 760°C.

2. Corrosion Resistant: Nickel alloys provide Corrosion resistance when used with corrosive media. As with other corrosion types, there are several aspects that impact the rate of attack. A corrosive medium is a key factor that governs the corrosion of a metal.

3. Low-Expansion: It is observed that Nickel has an intense influence on the thermal expansion of iron. Nickel- iron alloys are designed for a very low thermal expansion or exhibit constant and predictable expansion over a certain temperature range. Iron-36% Ni alloy, which has the lowest expansion of the Fe-Ni alloys, retains almost constant dimensions, even in the case of normal variations in the atmospheric temperature. If you add cobalt to the nickel-iron matrix, it produces alloys having high strength, a constant modulus of elasticity, and a low coefficient of expansion.

4. Electrical Resistance: Several nickel alloys or those containing high nickel contents find application in control equipment and instruments to measure electrical characteristics. They are also used in furnaces and appliances to generate heat.

Applications of Nickel Alloys

Nickel alloys are used for a wide variety of applications, some of which are as follows-

1. Nuclear power systems
2. Aircraft gas turbines
3. Medical applications
4. Steam turbine power plants
5. Chemical and petrochemical industries

Apart from the other uses, the nickel alloy steel pipe is widely used in the shipbuilding industry. The lightweight feature and properties are the best element for offshore piping. Those who want to use it on a large scale can get it at a very reasonable price. However, this specific type of piping requires additional care for transporting and expert welder to finish the task.

Above mentioned properties and applications of nickel alloys will help you understand why nickel alloys are the first choice in various industrial applications.
