The residue oil water cooler leaks frequently, with a leak occurring every two months. Dear experts, please provide an analysis

Frequent leaks are affecting production. Give it some analysis, offer some suggestions
The cause of the leak should be investigated, such as corrosion, impact wear, overpressure use, and others. For chemical corrosion issues, heat exchangers made of corrosion-resistant materials should be chosen. For physical impact wear, filtering before the cooler or adding parallel heat exchangers can be considered to reduce the impact wear on the equipment caused by high flow rates. The equipment should be used within the permitted limits; do not attempt to use it beyond these limits, as this may cause damage to the equipment. Another possibility is that the equipment is in service beyond its intended lifespan. For reference.
Is it the type that generates steam from a boiler, or just a simple water cooler?
Where was the leak? The tube bundle usually lasts for three years; has it exceeded its service life?
Leakage in the residue oil water cooler – I’ve never encountered that before. Generally, water coolers aren’t used in such applications; since the temperature of residue oil is high, water coolers suffer from severe scaling problems
If it’s convenient, please send some pictures of the leaks and describe the exact locations, etc.; this will also help everyone analyze them better.
If the specific process, medium temperature and pressure, as well as the specifications and material of the water cooler can be provided, it will likely help everyone to offer feasible opinions or suggestions.
Large temperature difference between heat exchange media； The crude oil has a high sulfur content.
Process changes have been made; let’s observe for the coming year. Feel free to ask if you have any more questions
