Alloy 20 Tube / Tubing / U-Bend Tube is made up of a nickel chromium molybdenum alloy. It has high nickel content of 32-38%. It is used mostly for applications that involve sulfuric acid. We are a leading supplier and manufacturer of alloy 20 tubing. Alloy 20 Nickel Tubing has nickel, chromium, carbon, copper, molybdenum, manganese, silicon, niobium and other elements in its chemical composition. The copper content is mostly responsible for the sulfuric acid resistance. There are seamless and welded tubes. The UNS N08020 Seamless tube can range from 0.375 inches to 1 inches in outer diameter where the welded tube can range from 0.125 inches to 1 inches. Also the wall thickness varies to seamless and welded pipes.

 

High Pressure Alloy 20 Nickel Tubing Supplier, Check Weight Chart of UNS N08020 Seamless tube

The welded tubes can have from 0.35 inches to 0.109 inches of wall thickness while the seamless ones have only up to 0.065 inches. The ASTM B729 alloy 20 tubes are of the welded pipe specification. With annealing, the minimum tensile strength of the material is at 551MPa and the minimum yield strength is at 241MPa. The alloy 20 seamless tubing has a high melting point of 1443 degrees Celsius. This allows the tubes to be used in high temperature applications. The ASME SB729 Tube is meant for high temperature, high pressure tubing. The copper content along with the high nickel content allows the tubes to operate under high temperatures with high acidic contents. Sometimes, the heat exchanger tubes of this grade are called the Alloy 20 U Tube because they are manufactured in the U shape.
