Pipes and tubes are required in our day-to-day life. They are made up of different materials. One such type of pipe is Alloy 20 Seamless Pipe which is an iron, chromium, and nickel base austenitic material. It can resist acid attacks mainly in sulfuric acid. It also resists general corrosion. These pipes are also known as Carpenter 20 pipes and are said to resist crevice corrosion and pitting in a chemical containing environment. Furthermore, they also resist phosphoric and nitric acid corrosion very well. Alloy 2.4660 Round Pipe also offers resistance to stress corrosion cracking in boiling 20% - 40% sulfuric acid.
ASME SB 729 UNS N08020 material displays excellent mechanical properties and is easy to fabricate. This alloy can be stabilized by the addition of an element called niobium which helps in resisting intergranular corrosion. Werkstoff 2.4660 Alloy 20 Welded Pipe also displays low carbide precipitation during the welding process. These pipes are widely used in heat exchangers, pickling equipment, and mixing tanks. Furthermore, Incoloy Alloy 20 ERW Pipe can also be used in plastic, petroleum, food, and pharmaceutical industries. Alloy 20 tube displays excellent chemical properties at ambient and high temperatures up to 930 degrees F.
