What is the cause of the inner-leakage between the two media in the heat exchanger?
（1）Perforation and cracking of heat exchange tubes due to corrosion
（2）The expansion mouth of the heat exchange tube and tube plate is cracked.
（3）Sealing leakage of float head flange of heat exchangers
（4）Seal leakage of threaded tight-ring type heat exchanger tube plates

How to deal with the internal leakage of two media in the heat exchanger?
（1）Replace or block the leaky tube.
（2）Expand again (repair welding) or make some blockage.
（3）Fasten bolts or replace sealing gaskets.
（4）Tighten inner ring compression bolt or replace the packing (gasket).
