Abstract:

To solve the leakage of steam-water corrugated-tube heat exchanger in hydrogen plant, the causes of the leakage of heat exchanger tube bundle were analyzed combined with the specific operating conditions, the analysis results were obtained combined with the actual inspection report based on the corrosion mechanism of corrugated tubes in the environment of chlorine-containing medium, and some specific preventive measures were developed correspondingly based on the cause analysis. The corrosion hazards were completely eliminated through heat exchange tube modification, the operating cycle of the heat exchanger was extended, and the long-term operation of the heat exchanger was ensured.

Key words: steam-water heat exchanger, corrosion, leakage, improvement
