Uses of Alloy 20 Pipe

Alloy 20 is one of the super stainless steels designed for maximum acid attack resistance. The nickel, chromium, molybdenum, and copper composition contributes to its overall resistance to the cracking and general pitting assault of chloride on stress corrosion. The alloy is stabilized with columbium to prevent carbide precipitation during welding.

Alloy 20 pipe has high mechanical properties and is quite simple to make. While the alloy was designed for use in industries using sulfuric acid, it is most usually seen in the chemical processing industry. Manufacturing also involves the use of pharmaceuticals, foods, petroleum, chemicals, polymers, explosives, synthetic materials, and a variety of other materials

Furthermore, this exceptional alloy is required in high-temperature exchangers, combining tanks, metal washing, dissolving equipment, and pipes. When compared to higher nickel-based alloys, Alloy 20 Pipe may offer cost benefits when making standard stainless steel.

To begin with, Alloy 20 pipes are commonly used in chemical and related industries, heat exchangers, food and dye manufacturing, SO 2 scrubbers and other harsh environments, pickling racks, tanks, and valves.

Alloy 20 Pipes are used in a variety of industrial applications, including food manufacture, construction, the chemical industry, petrochemicals, pharmaceuticals, oil exploration, power generation, the pulp and paper industry, condensers, heat exchangers, and so on.

Chemical production, petrochemical and refining, maritime, pharmaceutical, and food processing are all applications for alloy 20 pipes. End-use applications include storage facilities, mixing tanks, agitators, pump and regulator modules, food processing equipment, fasteners, and fittings. According to ASME, applications are limited to a maximum temperature of 1000 degrees F. It is also necessary to determine if the desired corrosion resistance can be attained within the given environment. 

What are the distinguishing characteristics of Alloy 20 Pipes?

  • Alloy 20 pipes offer several excellent features that you should be aware of. These are their names:
  • In boiling 20 to 40% sulfuric acid, they show higher resistance to stress-corrosion cracking.
  • Alloy 20 pipes are also resistant to chloride stress corrosion cracking and have high overall corrosion resistance to sulfuric acid.
  • They also have excellent mechanical qualities, are extremely fabricable, and have very little carbide precipitation during welding.
