Rim Clamps: High Pressure Pipe Repair & Reforming Out-Of-Round Pipe

The Mathey Dearman Rim Clamp is built for tough reforming jobs with out-of-round pipe. Our industry-leading rim clamps are ideal for high-pressure pipe repair and other applications requiring 100% weld and grind without releasing clamping pressure. Symmetrically placed jackscrews apply pressure on high points to precisely reform and align pipe or shells. All surfaces of the Mathey Dearman Rim Clamp in contact with the pipe are made of stainless steel, enabling this high-pressure pipe repair clamp to be used on a variety of materials.
