Alloy Steel Tube ASTM A213 T22 Seamless Boiler Tube For Fired Heaters And Heat Exchangers
ASTM A213 T22 is a specification for seamless ferritic and austenitic alloy steel boiler, superheater, and heat-exchanger tubes. These tubes are commonly used in high-temperature applications in power plants, refineries, and other industrial settings. The T22 designation indicates that the alloy steel tube is made from a material that contains 2.25% chromium and 1% molybdenum, which gives it improved corrosion resistance and high-temperature strength. This alloy steel tube is suitable for operating temperatures up to 600°C (1112°F).
ASTM A213 T22 seamless alloy steel tubes are available in various sizes and thicknesses to meet specific application requirements. They are typically used in high-pressure and high-temperature environments where resistance to corrosion and thermal stress is crucial. These tubes are usually supplied in the normalized and tempered condition, which ensures high strength and toughness. There are many good qualities like high tensile strength, high durability, flexibility, non-corrosive, longevity, tough construction, hardness. Also, ASTM A213 T22 seamless alloy steel tubes have excellent resistant ability against general corrosion, stresses corrosion cracking, crevice corrosion, pitting and oxidations.
