PROLINE Pipe Bending Mandrels are a vital piece of equipment for any pipe bending operation. Using the latest technologies and materials, PROLINE mandrels are guaranteed to withstand the extreme forces of bending. Our unique wedge design allows smooth bends to be made while preventing pipe buckling and shape distortion of higher grades of pipe. PROLINE’s self-centering / no-roll technology insures that the mandrel will always stay centered in the pipe. Designed and engineered for a one-man operation, PROLINE mandrels come in hydraulic or pneumatic wedge styles. Comes in a variety of sizes for different pipe diameters. Features: Extremely powerful large diameter cylinders. Polyurethane-coated backing bars, pads and wheels for the protection of internal coated pipes. Can be used with X65 to X80+ grade pipe. Conversion kits available to adjust for different pipe size in range. Self propelled air motor (some hydraulic motor driven) – 20″ and larger. Fast Action – retracts, expands and travels quickly. Rugged and built for long life. Very low maintenance.
