High Pressure Piping in the High Pressure synthesis section of a urea plant deserves the Best Quality and Maximum Reliability. The integrity of High Pressure Piping can be at risk due to internal and external corrosion phenomena. At regular time intervals corrosion inspections are advisable certainly in older age urea plants.
BHDT has the experience and Know How available to assure you Best Quality and Maximum Reliability. With BHDT Services, BHDT provides added value to its clients by offering Full Life Cycle support for the complete High Pressure Piping system. The activities of BHDT Service include all activities related to High Pressure piping systems during the complete lifetime of a urea plant; from Basic and Detailed Engineering, Installation services, Corrosion Inspections, Troubleshooting, Emergency supply/repair, Spare Parts Management up to Training Programs.
This paper describes the Digital Radiography Corrosion Inspection Services, which BHDT Service has provided to Nitrogenmuvek Zrt. in Hungary in April 2010. The corrosion analysis technique applied was a worldwide first time application of such a technique in a urea plant. This technique was considered by Nitrogenmuvek Zrt. very attractive as the internal corrosion phenomena could be analyzed while the plant remained in operation. The results were fit for purpose and provided Nitrogenmuvek Zrt. with the necessary information for the decision which piping needed to be replaced. Accordingly Nitrogenmuvek Zrt. could order the required material in time and replace the critical High Pressure piping in the scheduled turnaround of July 2010.
