introduction
A335 P22 alloy pipe is ASTM A335/A335M standard seamless steel pipe, which is a 2.25Cr-1Mo chromium pipe for boilers and superheaters.
A335 P22 alloy steel pipe is 2.25Cr-1Mo chromium-molybdenum high-temperature ferritic steel for boilers and superheaters. It is a high-temperature and high-pressure pipeline material used in power plants.

What is the difference between A213 T22 tube and A335 P22 tube?
The chemical composition and properties of T22 and P22 alloy steel pipes are similar. T22 is used on the heating surface of the boiler and is in direct contact with the flue gas. Seamless steel pipes are used to connect pipes. T/P22 is equivalent to German 10CrMo910. T22 belongs to ASTMSA213 boilers, superheaters and heat exchangers. Seamless ferritic and austenitic alloy steel pipes for appliances, P22 belongs to ASTM SA335 seamless ferritic alloy steel pipes for high temperature.

What material is the A335-P22 made of?
A335-P22 implementation standard: American standard ASTM A335/A335M-2003
Chemical composition of A335-P22: C 0.05~0.15 Mn 0.30~0.60 Si ≤0.50 P ≤0.25 S ≤0.025 Cr 1.9~2.6 Mo 0.87~1.13.
Purpose: Working temperature 540-750 degrees, high temperature working environment, high pressure, ultra-high pressure, subcritical power station boilers, superheaters, headers and main steam pipelines, etc.
