The real-time pit-detection monitoring for weight-loss coupons is impossible for a long exposure time, and the ER technique can only show uniform corrosion. The real-time corrosion monitoring of pitting corrosion is essential since most pipeline failures are due to pitting corrosion rather than general corrosion.

NexCorr provides a multi-functional probe which is able to monitor pit dete-ction using PDS (pit detection probe) and general corrosion rates using electrical resistance (AI ER (i-ER)).

Advantages :

• Usable in any environmental conditions
• No modification of port is necessary because pit detection probe can be installed at the “existing port for ER or weight loss coupon”.
• Real - time pit detection and general corrosion rate monitoring.
• Pit penetration rate can be easily monitored.
• Any change of field conditions during the monitoring does not have any problems.
