Abstract: An apparatus for straightening associated heavy wall tube provided in a coiled configuration at a worksite. The apparatus includes a frame that rotatably receives associated heavy wall tube in a coiled configuration. A straightener device has multiple rollers arranged so that tangents of the rollers receive the associated tube in a linear fashion between the rollers, none of the rollers being powered to rotate. A tube puller engages the tube adjacent a first end thereof, the tube puller moving relative to the frame for advancing the tube from the coiled configuration through the rollers of the straightener device. A truing device rounds the tube after the tube has left the straightener device, the truing device including multiple rollers and none of the rollers are powered.
