Preferential Weld Corrosion (PWC) susceptibility was studied in a slightly sour wet gas piping system using electrochemical methods based on the “hockey puck” technique. Several corrosion inhibitors were evaluated to assess their performance in suppressing PWC.

Preferential Weld Corrosion (PWC) susceptibility was studied in slightly sour wet gas piping system using electrochemical methods based on the “hockey puck” technique. By establishing a benchmark testing environment that simulates the operating conditions several corrosion inhibitors were evaluated to assess their performance in suppressing PWC in static conditions.The results show that under the testing conditions the Heat Affected Zones (HAZ) from the welds are susceptible to PWC. Also pitting occurs across all the components of the weld independently of the relative cathode / anode relationship. Profilometry assessment of the specimen after exposure supports the findings from the electrochemical measurements. The corrosion inhibitors dosed at 100 ppm concentration in static conditions show reduction of PWC and pitting severity.

The work conducted produced conditions where preferential weld corrosion initiated in uninhibited conditions and was sustained throughout inhibition. Two types of weld metallurgies; one weld consumable with 1% nickel, the second matched the parent pipe.
