ASME SA213 tubing

ASME SA213 is the standard of American Society of Mechanical Engineers; while ASTM A213 is the standard of American Association of Materials and Test.
ASME SA213 tubing is mainly used in boiler tube and superheater. The boiler general adopts the minimum wall thickness seamless ferritic and austenitic steel tube; superheater adopts austenitic steel pipe. The grades Of ASME SA213: A213T11、A213T12、A213T22 etc.
