Dual-element transducers
10/06/2021
Olympus’s new DC series (DC1 to DC5) dual-element transducers provide inspectors with a complete corrosion monitoring toolbox for pipeline and tank integrity. Optimised for corrosion and thin materials, the transducers work with the non-destructive testing instruments and ultrasonic inspection procedures used in the oil & gas, energy and mining industries.Depending on the application, any one of these transducers, or a combination of them, offers improved corrosion monitoring and defect sizing. As field inspections change, inspectors can benefit from having the complete set of transducers with a total combined thickness range of
0 to 50.8 mm, as well as the extra pipe weld inspection tool with the DC3 model.
All models provide a cleaner signal than single-element transducers and offer less ring down than comparable models, which is helpful for resolving smaller defects, inspecting close to the surface and differentiating between two indications.
Hard-to-access areas, such as boiler tubes, can be inspected thanks to the low-profile designs and small tip diameters (DC1 and DC2), as well as integrated wedges (DC3).
The DC3 model takes the series beyond corrosion monitoring and thickness measurement to include pipe weld testing and other thin-wall material inspections. Fast and reliable, the transducer performs high-speed manual weld inspections similar to comparable models.
Featuring a thick-walled wear-resistant housing (DC2 model) and replaceable wedges (DC4 and DC5), the transducers are built to last. A heat-resistant delay line up to 150°C on the DC1 and DC2 models helps reduce maintenance time for elevated-temperature pipe and tank inspections.
Pairing the transducers with the Olympus Epoch™ 650 or 6LT flaw detectors or the 38DL Plus™ thickness gauge enables accurate and efficient corrosion mapping.
