Abstract: PURPOSE:To prevent an indentation flaw by performing a forming by using the roll having the flower making the cross diameter of the forming flower of each stand of a fin pass roll larger according to going to a downstream from an upperstream. CONSTITUTION:A strip steel blank is bitten into a 1st upperstream fin pass roll. The roll is composed of the pair of the upper roll of the vicinity of a fin 6A being a radius Ru and the lower roll of the radius at the center part of a recess being Re and a gap g1 is formed on the upper roll 1 and lower roll 2. An open pipe 3 is then bitten into a 2nd fin pass roll consisting of the upper and lower each roll having a slightly larger forming flower cross diameter W2, subjected to a pressure forming and fed to the suceeding fin pass roll. A flange part is therefore not brought into contact strongly and no indentation flaw is caused. After performing the pressure forming up to the final fin pass roll in other like this a butt part is welded with constraining it by a squeezing roll and a specified electric welded pipe is obtd. by adding a welding by making a round pipe with a sizing roll.
