Cold drawn seamless steel pipe production method

- Feb 11, 2019-


Cold drawn seamless steel pipe production methodology


No spindle drawing (no mandrel is required for tube drawing only);


Drawing of short spindle (pipe drawing die and short mandrel with fastened axial length for drawing);


Draw-out of long spindle (draw-out die and long mandrel that moves slightly longer than the length of pipe along side the drawn pipe)


Drawing of moving spindle (drawing with tube drawing die and short mandrel which may keep stable in deformation zone while not axial fixation).During the primary 2 sorts of production on the applying is especially pervasive;Non-mandrel drawing is employed to scale back the skin diameter of the steel pipe;The alternative 3 kinds of drawing with spindle is primarily wont to tighten the thickness of the steel pipe wall, at the side of an exact reduction deformation.
