Localized corrosion damage is tough to detect because its causes - pitting and/or SCC - may be long in initiation and unpredictable in terms of propagation. But the Pocket CORPAC™ detects active, localized corrosion without external loading or relaxation of stress from existing damage. In essence, the problem is discovered before it causes damage.
Real-time corrosion monitoring can identify areas of concern in a variety of industrial structures, which in turn can not only prevent leaks or damage, but also the propagation of localized corrosion like pitting and/or SCC.
Spot monitoring with the Pocket CORPAC™ provides users with the option to schedule full inspections based on the presence of active corrosion. Pocket CORPAC™ is at the center of any predictive maintenance and inspection program aiming to identify potential degradation as early as possible.
Technology Behind It
The detection of localized corrosion is difficult because its processes (cracking and pitting) have unknown times of initiation coupled with unpredictable speeds of propagation. Yet the AE technology in the Pocket CORPAC™ is able to "listen" to the subtle signals SCC and pitting emit. The Pocket CORPAC™ hardware is capable of high-speed data acquisition and waveform processing thanks to its 16-bit A/D converter and parallel DSP processor.
