ASTM A213 T22 seamless steel boiler tube 5" XS 12M length
ASTM A213/ASME SA213 Standard: Seamless Ferritic And Austenitic Alloy-Steel Boiler, Superheater And Heat-Exchanger Tubes
ASTM A213 or ASME SA213 seamless tube is applicable to seamless ferritic and austenitic pipes with the minimum thickness in boiler and superheater. It is typically used as heating surface pipe, boiler header (collection box) and steam pipe in low and medium pressure boilers (The working pressure is not additional than 9.8 MPa and the running temperature is between 450℃ and 650℃.), economizer, superheater, reheater, etc. This seamless steel pipe is widely applied in heat exchanger, condenser and heat transfer equipment.
