How can high-temperature heat exchangers be prevented from leaking?
Thread Content
High-temperature heat exchangers are used for heat exchange between heat transfer oil and the material being processed; the temperature of the heat transfer oil is 330°C. There have been several instances of leakage, and I would like to ask if anyone has any methods to reduce such leakage. Which brand of heat exchanger do you use, and what is the performance of those exchangers? Which heat exchanger manufacturers are good? Thank you.
What is the structure of the heat exchanger, and where is it leaking? Please describe it in detail, or send a picture

There are many reasons for heater leaks: improper material selection, unsuitable design, inadequate sealing performance due to poor matching of gaskets and fasteners, differences in pressure between the tube side and shell side, and even manufacturing issues. As for the leaks you mentioned, where do they usually occur?
There are generally several reasons for leaks: 1. Design: Selection of components, as well as detailed design for high temperatures 2. Manufacturing: Manufacturing experience, process level 3. Inspection: 4. Run:
Since it keeps leaking, it is recommended to scrap it and purchase a new one.
First, from the perspective of design; second, from the perspective of operations during production
During operation, care should be taken to ensure that there are no significant fluctuations in pressure, temperature, and flow rate. I’m not sure what type of heat exchanger is being used
Is it because the temperature fluctuates frequently?
