GE Krautkramer ROTA Ultrasonic Testing Machine Series
GE supplies the Krautkramer ROTA systems which, depending on the client’s requirements, can be configured for individual manual, central or motor adjustment, and are notable for highly repeatable results. A probe revolution rate of 6000-8000 rpm provides highest productivity rates.
In addition to defect detection, Krautkramer ROTA systems can also be used for geometry checking. The systems are well known for high test accuracy, repeatability of results, and test speed. Flaw-type defects throughout the material cross-section, and divergences in the dimensions for internal and external diameter, wall thickness, ovality and eccentricity can all be detected in a single inspection cycle. A manual probe fine-adjustment system is installed as standard. It enables fast and repetitive adjustment. The equipment is fitted with single or multiple probes, depending on the particular test application. Single or multi-channel, manual or computer-controlled, parallel scanned inspection electronics systems are used, depending on the equipment configuration. Many test standards require a second, independent physical test procedure. GE fulfils this specification via the integration of Eddy Current test systems.
Nonferrous tube testing
GE Krautkramer ROTA test systems have their origins in high-precision testing of tubes and heat-exchanger tubes for nuclear applications. Krautkramer ROTA 25 and Krautkramer ROTA 45 Z inspection systems are designed for this dimension range. The Krautkramer ROTA Z is a derivate from the standard Krautkramer ROTA line with central probe adjustment capabilities for fast changeover times. The Krautkramer ROTA and ROTA Z systems are conform to the extremely strict inspection requirements for nuclear specifications and permit not only defect detection but also complete geometrical checking of the tube cross-section, including internal and external diameter quality and eccentricity. These systems are in use with virtually all manufacturers of nuclear piping around the world.
Testing of hot-processed tubes and bars
Hot-processed tubes and bars necessitate special design features for test and inspection systems, in terms of surface quality, fouling, coarse manufacturing tolerances, test throughputs and test speeds. GE meets these requirements with its Krautkramer ROTA S systems, a special water routing and cleaning system reliably removes particles from the probes.The Krautkramer ROTA S series was specially developed for hot processed tube with rough surfaces, bend tolerance greater than standard API specification and including tubes with upset ends. Unlike the conventional Krautkramer ROTA systems, the Krautkramer ROTA S features a central probe distance adjustment system providing extremely fast change of material dimensions.
