Application of ASTM A213 Alloy Seamless Steel tubes
Pipe ordered under this specification is for manufacturing wall panel,economizer,superheater and steam pipeline of boilersDetails of ASTM A213 Alloy Seamless Steel Tubes We can supply
Manufacture: Seamless process, cold drawn or hot rolled Size: O.D.: 15.0～200mm W.T.: 2～25mm Grade: T11,T12,T13 Length: 6M or specified length as required. Ends: Plain End, Beveled End.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.Chemical Composition and machenical properties of ASTM A213 Seamless Alloy Boiler tubes
