ASTM P22 Seamless Steel Alloy Pipe

P22 A335P22 is a grade in ASTM A335/A335M standard, which is 2.25Cr-1Mo chromium molybdenum high temperature ferritic steel for boilers and superheaters. Alloy steel material ASTM-A335P22, high temperature and high pressure pipeline material for power plants. The chemical composition and performance of T22 and P22 are similar. T22 is used for the heating surface of the boiler and is in direct contact with the flue gas. P22 is used for connecting pipes. T/P22 is equivalent to German 10CrMo910. T22 belongs to ASTM SA213. Ferritic and austenitic alloy steel pipe (Tube), P22 belongs to ASTM SA335 seamless ferritic alloy steel pipe for high temperature.

Alloy Steel pipes have hollow sections and are widely used as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, alloy steel tube is lighter in weight when the bending and torsional strength is the same. Alloy steel pipe is an economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission Axles, bicycle racks and steel scaffolding used in building construction, etc.
