ASTM A213 Gr T22 Tubing

Specifications: ASTM A213 T22, ASME SA 213

Dimension: 1/8” to 24”

Wall thickness: SCH10 to 160

Length: 1m to 12m or custom Length

Application: For superheater, reheater pipe, header and steam pipe under 600℃ in high pressure, ultra-high pressure and subcritical power station, nuclear power heat exchanger and oil cracking unit furnace pipe.

Grade T22 steel is a type of 2.25Cr-1Mo low alloy steel, which has high thermal strength, good oxidation resistance, hydrogen corrosion resistance and welding performance. It is widely used in high-temperature equipment such as petrochemical, nuclear power and boilers systems of the power plant.

WIHO metals is a leading seamless alloy steel tube supplier and manufacturer, we supply ASTM A213 Grade T22 alloy steel pipe and their equivalent material for boiler systems in various sizes and specifications. If you are looking for this material, please contact us or get a quotation.

 

Grade T22 and P22 tubing

Grade T22 and P22 steel pipe have a similar chemical composition( 2-1/4 Chromium, 1 Molybdenum alloy )and mechanical property. They have exceptionally high creep properties, has been widely used in high pressure, ultra-high pressure, subcritical power station boiler superheater, header and main steam duct. As for their difference, T22 steel tubing belongs to ASTM A213 which does Ferrite and Austenitic boiler, superheater and heat exchanger seamless steel tube. But for ASTM A335 P22 tubing, they intended for Ferritic and alloy seamless steel tube intended for high-temperature service, we can say that they have been substituted for another one when the same purpose.
