Astm A213 T11 Seamless Tube - China

ASTM A213 T11 is the part of ASTM A213 Standard Specification for

Seamless Ferritic and Austenitic Alloy- Steel Boiler, Superheater, Heat-

Exchanger Tubes.

These different requirements provide higher creep- rupture strength than normally achievable in similar grades without these different requirements.

ASTM A213 T11 tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified.

Grade TP347HFG shall be cold finished.

Heat treatment shall be done separately and in addition to heating for hot forming.

The ferritic alloy and ferritic stainless steels shall be reheated.

On the other hand, austenitic stainless steel tubes shall be furnished in the heat- treated condition.

Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means.

Tension test, hardness test, flattening test, and flaring test shall be done to each tube.

Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test.
