Standard: ASTM A213/ASME SA213
Application of ASTM A213 Alloy Seamless Steel tubes:
Pipe ordered under this specification is for manufacturing wall panel, economizer, superheater and steam pipeline of boilers
Manufacturing Process of ASTM A213 Alloy Seamless Steel Tubes:
ASTM A213 alloy seamless steel tubes are produced either by cold-drawn or hot rolled, 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.
