To provide a method for rolling a seamless steel pipe capable of suppressing the generation of non-uniform thickness, and rolling high quality hollow pipes in the method which performs, holding a hollow pipe with a holding device, a rolling to form a solid-core or hollow material to be rolled into a hollow pipe with a skew roll and a plug provided on the leading end of a core bar held by a plural holding devices placed in the exit side of the skew roll.

The ratio (PB/dB) between the holding pressure PB (unit: MPa) of the core bar which holds the core bar with the holding device and the outer diameter dB (unit: mm) of the material to be rolled is made 0.020 or more and 0.100 or less and when the ratio (Ps/ds) between the pipe holding pressure Ps (unit: MPa) at the time of holding a hollow pipe by the holding device and the outer diameter ds (unit: mm) of the hollow pipe is 0.002 or more and 0.020 or less when the ratio (ts/ds) between the wall thickness ts of the hollow pipe and the outer diameter ds is 5% or less, 0.004 or more and 0.040 or less when the ratio (ts/ds) is more than 5%.
