Electrochemical Hydrogen Patch Probe Correlated to Corrosion Rate in a Slightly Sour Water Flood

Source

An externally mounted electrochemical cell has recently been developed that can be patched onto the outside of steel pipes and vessels. This probe monitors the amount of hydrogen diffusing through the steel walls.

The hydrogen patch probe was mounted on a slightly sour water flood line 9.1440 m (30 ft) upstream of a corrosion coupon rack. Real time hydrogen current levels are compared to weekly weight loss corrosion measurements for a period of six months. Areas of agreement and disagreement are discussed.
