Learn About The Applications Of Alloy 20 Pipes

One of the “Super” stainless steels, Alloy 20, was designed for the best acid attack resistance. The presence of nickel, chromium, molybdenum, and copper increases the material’s resistance against chloride attack by stress corrosion, which can cause cracking and general pitting. The alloy is stabilized with columbium to prevent carbide precipitation when welding.

It can be made quite easily and has strong mechanical properties. Although the alloy was created for use in sectors related to sulfuric acid, it is most frequently employed in the chemical processing sector. Additionally, used in manufacturing include pharmaceuticals, meats, oils, plastics, explosives, synthetic fibers, and many more.

This excellent alloy is also necessary for high-temperature exchangers, combining tanks, metal cleaning, pickling equipment, and pipes. Alloy 20 Pipe might save costs when producing standard stainless steel compared to higher nickel-based alloys.

What distinguishing qualities do Alloy 20 pipes have?

You should be aware of several excellent characteristics that the pipes made of alloy 20 feature. These are what they are:

  • They are more resistant to stress-corrosion cracking in boiling sulfuric acid (20–40%).
  • Alloy 20 pipes have excellent overall corrosion resistance to sulfuric acid and resistance to chloride stress corrosion cracking.
  • They also have excellent fabricability and mechanical properties, as well as low carbide precipitation when welding.

What is the use of Alloy 20 Pipes?

Alloy 20 pipes are frequently used in pickling racks, tanks, valves, SO2 scrubbers, food and dye manufacturing, chemical and related industries, heat exchangers, and other harsh conditions.

Numerous industrial applications, including those in the production of food, building, chemistry, petrochemistry, pharmaceuticals, oil exploration, power generation, pulp and paper sectors, condensers, heat exchangers, etc., employ alloy 20 pipes.

Chemical production, petrochemical and refining, maritime, pharmaceutical, and food processing are just a few industries that employ alloy 20 pipes. End-use applications include storage tanks, mixing tanks, agitators, pump and valve modules, food processing machinery, fasteners, and fittings. Applications are restricted to a maximum temperature per ASME of 1000 degrees F. It’s crucial to determine if the needed corrosion resistance can be attained in the environment at hand.
