Testing sealing surfaces for cracks and determining the crack depth are also included in DELTA TESTS range of services. To perform the tests, it is vital to guide the probe system coplanar to the test surface and at always the same distance. For this, flange diameters from DN 50mm up to DN 750mm, whose orientation and position is arbitrary, are tested. This diversity of tasks was achieved through combination of a probe bracket and guide principle with a very effective sensor guide: with the superposition of translational and rotatory movement of the sensor, faults oriented in any direction are detected.
The same equiment can also be used for the inspection of bores and threads.
