A pipe straightener employs parabolic-shaped upper and lower rollers in conjunction with hydraulic cylinders to exert pressure between alternating parabolic rollers. This process eliminates any bends and twists in the pipe as it is fed through the rollers. The machine offers flexibility in straightening pipes by allowing the adjustment of the top and bottom rollers. They can be set anywhere from a right angle with respect to the pipe, up to approximately 45 degrees. The upper rollers can be adjusted in the opposite angular direction compared to the lower rollers.
