What Are The Uses Of Alloy 20 Pipe?

Alloy 20 pipes are created by combining steel and nickel. Nickel-chromium alloys, like alloy 20, have a high melting point since more than 90% of them are nickel and chromium. In the natural gas sector, pipes made of alloy 20 are used to transport hydrocarbons like gas and petroleum. Extreme situations in terms of stress, temperatures, and chemicals makeup are all supported by the alloy 20 pipe. As a result, it can be employed in the riskiest circumstances when other materials would fail.

The exceptionally durable Alloy 20 Pipes is frequently used in pipelines that are buried or submerged in water. This pipe can be used for extended periods of time without disintegrating or degrading because to its strength and endurance.

When alloy 20 pipe is exposed to water or other liquids, like gasoline, it is coated with rust-resistant coating that prevents it from rusting. By contacting water instead of air, these pipes will not corrode and will not leak when shipped or stored at various sites around the world because they won’t corrode if they contact water instead of air.



Many industries make use of alloy 20, including food processing, pharmaceuticals, maritime, petrochemicals, refinery, and chemical processing. Also from pumps, valves, fasteners, kitchen appliances, fittings, agitators, mixing tanks, and storage tanks uses alloy 20.

According to ASME, maximum temperatures are 1000°F for applications. Furthermore, it is crucial that this be verified in order to achieve the necessary corrosion resistance in the specific environment.


A traditional technique for producing Alloy 20 Pipes is by cold-working or hot-working. It is important to carefully control the temperature of hot forged material between 2100°F and 2250°F in order to properly heat it. It ensures that the material does not freeze below 1800°F before it can be forged. An annealing process should follow hot working by heating the materials to 1725°F and 1850°F for at least 30 minutes per inch of thickness, followed by water quenching.

A water quench is followed by heating to a temperature below 1000°F when the temperature needs to be warmed to relieve stress. It may occur after the required time has lapsed after reaching a certain temperature. For an inch of thickness of Alloy 20, annealing must take place at a temperature between 1725°F and 1850°F for 30 minutes.
