In April this year BHDT Service has performed a Digital Radiography corrosion inspection at Nitrogénmuvek Zrt. in Hungary while the plant was in operation. The corrosion analysis technique applied was a worldwide first time application of such a technique in a urea plant. This technique was very attractive for Nitrogénmuvek Zrt. as the internal corrosion phenomena could be analyzed while the plant remained in operation. The results were fit for purpose and provided Nitrogénmuvek Zrt. with the necessary information for the decision which piping needed to be replaced. Accordingly Nitrogénmuvek Zrt. could order the required material in time and replace the critical High Pressure piping in the scheduled turnaround of July 2010.
