Orienting the tube’s weld seam on the mill

Tube producers need the weld seam straight up at the 12 o’clock position, but in some cases, after it’s welded they need it move it to some other location along the tube’s circumference. Many use a pair of football-shaped rolls installed in place of the first sizing pass, but another option is to use a seam orientation stand, a unit built specifically for this purpose.
