Abstract

PURPOSE:To obtain a finished pipe having desired dimensional specifications by correcting and controlling rolls based on the fluctuating patterns of the diameter of a mandrel bar used with respect to a reference mandrel bar in rolling a blank pipe inserted internally with the mandrel bar with mandrel mills. CONSTITUTION:The fluctuating patterns of the diameter of a mandrel bar used with respect to a reference mandrel bar of which the longitudinal distribution of the diameter is known are beforehand inputted to a control part 4. Next, a blank pipe 1 held inserted with a mandrel bar 2 is passed through mandrel mills. Thence, the blank pipe is rolled by the whole of stands 31-38 or by the rolling rolls 31a, 32a,... 38a of which the peripheral speeds and/or roll gaps of specific stands are controlled by said control part 4 based on the correction control patterns having beforehand been inputted.
