Non-Intrusive Corrosion and Erosion Monitoring

The integrity of process piping is paramount to safe operations. Corrosion and erosion monitoring, especially for processes with challenging fluids, play an important role.

This short 2:10 YouTube video, Permasense ET210 Integrity Monitoring System, shows how piping erosion and corrosion can be monitored with pipe wall thickness measurements with non-intrusive wireless sensors strapped to the pipe. These sensors are yet more building blocks in the Industrial Internet of Things (IIoT) to monitor and provide early warning to improve overall operations.

More than 10,000 of these ultrasonic, wall-thickness measurement sensors have been installed in process applications in temperatures up to 120degC. These sensors communicate via WirelessHART to analytics software, control and/or asset management systems to help spot problems before they lead to unsafe conditions.

The sensors strap on to the piping and are non-intrusive so they can be quickly installed and put into service. There is no need to remove the piping external coating for the sensors to measure pipe thickness. The sensors are installed on a wide range of piping including risers, flow lines, vessels and processing equipment. They are typically located in areas at elevated risk of corrosion and erosion such as piping elbows.

The thickness of the piping can be monitored over time to assess when a problem might develop and need to be addressed.

    Once you have a plant-wide wireless sensor network infrastructure in place you can support both wireless ER/LPR corrosion transmitters as well as wireless UT corrosion transmitters. That is, you can replace ER/LPR data loggers, coupons, as well as portable UT with wireless transmitters that send the data to you automatically. The more frequent updates make you more predictive, the automation makes your plant more productive. Learn more from this essay:
