The ASTM A213 T22 seamless boiler tubes are commonly used in high-temperature applications such as power generation, chemical processing, and oil and gas refining. They are designed to withstand high-pressure and high-temperature environments, making them suitable for use in boilers, superheaters, and heat exchangers.The T22 alloy steel used in the tubes contains elements such as chromium, molybdenum, and tungsten, which provide high-temperature strength, corrosion resistance, and wear resistance. The tubes are manufactured by a seamless process and are typically heat treated to enhance their mechanical properties.
