ASTM A 213 T22 Pipes,ASTM A 213 T22 tubes,ASME SA213 T22 Alloy Steel Seamless SMLS Tube
We are a professional ASTM A 213 T22 Pipes,ASTM A 213 T22 tubes,ASME SA213 T22 Alloy Steel Seamless SMLS Tube supplier and exporter in China.
ASTM A213 T22 Tube refers to a grade of seamless ferritic alloy steel tubes under the ASTM A213 standard. These tubes are widely used in high-temperature applications due to their excellent mechanical properties, resistance to oxidation, and ability to withstand high pressures. The Grade T22 is a chromium-molybdenum alloy steel specifically formulated for applications such as boilers, superheaters, and heat exchangers in the power and petrochemical industries.
We can supply both ASME SA213 T22 Straight tube and SA213 T22 U bend tube ,SA213 T22 Condenser and Boiler Tube
