POCKET CORPAC™
Portable Non-Intrusive Localized Corrosion Testing System

Non-Intrusive Corrosion Testing Capabilities... That Fit in the Palm of Your Hand!

The Pocket CORPAC™ combines an industry staple in non-intrusive corrosion testing with the portable convenience made possible by the latest in Acoustic Emission (AE) technology.

Built on the successful platform of the original CORPAC™ - the industry standard in corrosion detection since the 1990s - the Pocket CORPAC™ detects active localized corrosion as a result of pitting stress corrosion cracking (SCC) without taking industrial structures out of service.


At less than a quarter of the size of its predecessor and with the latest user-guided software, the Pocket CORPAC™ detects localized corrosion, before costly damage and its effects can be seen or felt.

The Pocket CORPAC™ increases operational safety with short periodic, in-service monitoring, while simplifying asset maintenance on a variety of industrial structures and materials, such as:

Industrial Structures
  • Storage tanks
  • Pipe connections
  • Reactors
  • Pressure vessels
  • Pipelines
  • Railroad tank cars
  • Distillation towers
  • And more

Industrial Materials
  • Stainless steel
  • Carbon steel
  • Aluminum alloys
  • Zircaloy
  • And more

The Solution

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.

Key Features/Benefits

Portability
  • Less than a quarter of the size of the original CORPAC™, the Pocket CORPAC™ was designed with portability and ease-of-use in mind. It builds on the original CORPAC's knowledge-based, "expert-system" software, which was developed over six years in a partnership between MISTRAS Group, SA (France), the European chemical industry and a French university, all in conjunction with a European Union Grant. We take full control of the acoustic signal processing and automated corrosion type classification.
  • The sleek, updated design can be used for many applications where portability is important. With a four-hour battery life and added ability to operate the unit from battery belt or AC power, the Pocket CORPAC™ can be used for long-term testing or carried into the field for on-the-spot inspections.
In-service Use
  • Included sensor holder/waveguide allows for testing on high-temperature structures
  • Able to be used in industrial high-noise environments, avoiding asset shutdowns
Simplicity
  • Turn-key Pocket CORPAC™ software is designed for non-AE specialists, guiding the user through the test and providing an output indicative of active, local corrosion. The software allows users to carry out on-site tests, perform diagnosis and create areport in PDF format.
Versatility
  • Pocket CORPAC™ provides fast diagnostics on a wide array of industrial structures.
