ASME SA213 T22 Seamless Boiler Tubes
ASME SA213 T22 seamless boiler tube is a steel grade in the ASME SA213/SA213M standard. It is a 2.25Cr-1Mo chromium-molybdenum high-temperature ferrite steel tube for boilers and superheaters.
ASME SA213 T22 alloy steel pipe has good processing performance and welding performance, good durable plasticity, and can operate in high temperature and high pressure environments for a long time, ensuring the stable and safe operation of equipment. Therefore, it has been widely used in harsh working environments, such as various heated pipes and high-pressure vessels in thermal power, nuclear power and some hydrogen-facing equipment.
SA-213T22 alloy boiler tubes are mainly used in superheaters of large-capacity power station boilers such as 300 and 600MW with tube wall temperatures ≤580°C and steam pipes and headers with tube wall temperatures ≤540°C
