Abstract: Elaborated in the article is the centrifugal casting process for manufacturing dual phase stainless steel tube for drum-making. Compared to the conventional coiling-welding process for the same purpose，the centrifugal casting process has obvious advantages. Relevant operational practice of producing the dual phase stainless steel tube for drum-making with the said centrifugal casting process is also detailed， involving such aspects as material chemical composition，casting speed and determination of the heat treatment process， etc. The results of relevant tests and inspections show that the drum fabricated with the dual phase stainless steel tube as produced with the above mentioned centrifugal casting mould RPM is in possession of such advantages as high density，very few defects like gas hole，trapped-slag and fine mechanical properties，being satisfactory to the requirement for manufacturing the seamless drum which is suitable for special service conditions.
