Do you need to disassemble the titanium heat exchanger when cleaning it?

If the dirt is serious, the blockage is complicated, or the structure of the heat exchanger is easy to disassemble and can be cleaned and inspected more effectively after disassembly, then disassembly cleaning may be a better choice.
However, if the dirt is relatively light, the heat exchanger structure is complex and difficult to disassemble, or the disassembly cost is high and may affect the sealing and stability of the equipment, then you can consider using online cleaning (i.e., no disassembly) methods, such as chemical cleaning, high-pressure water washing, etc.
