MRPC Probes Motorized Rotating Probe Coil (MRPC®) solutions are typically comprised of two pieces: a motor unit and a probe head. MRPC probes provide high resolution and inspection accuracy. The MRPC rotating head inspects 100% of the tube circumference, and the surface riding coils ensure minimum lift-off effect and maximum signal-to-noise performance. MRPC probes excel in finding longitudinal and circumferential flaws in critical areas of tube sheets, support plates, and U bends-even in difficult areas, such as deformed tube areas, roll transitions, dents, and regions affected by deposits. MRPC motor units are available in both brush and brushless designs optimized for torque and/or speed. MRPC probe heads are available in a variety of diameter and coil configurations. Modular Probe Heads with Extension Shafts The modular probe concept offers many advantages including faster inspection rates, reduced cost, less rad-waste, and less downtime. Modular probe heads feature interchangeable coil modules, a detachable nose cone assembly, and a detachable extension shaft. Individual components can be easily replaced instead of replacing the entire assembly. Various lengths of extension shafts are available to adapt to specific regions of the steam generator. MRPC Probe Motor Units High-Speed/High-Torque MRPC Motor Units have consistent rotation rates and increased motor torque to easily spin probe heads and shafts through restrictive tube areas and geometries. This includes square bends, ovalized tubes, dents, and tubes with heavy deposits on the inside diameter. |
