How to Repair Leaking Heat Exchange Tubes?
What are the leaking situations of the heat exchanger?
The heat exchanger leaks due to cracks and perforations caused by fluid medium corrosion, wear, scouring, assembly strain, defects in the tube itself, or large wall thickness deviations.
How to repair leaking heat exchange tubes?
(1) The leakage of the tube at the nozzle is generally repairable, but it cannot be repaired on the inside of the tube sheet.
(2) If there are not so many leaking pipes, and the blocked pipes can meet the production requirements, then the two ends of the pipe mouth can be plugged with a conical metal plugging head. If the pressure of the pipe pass is high, the end of the pipe mouth should be plugged and welded to avoid the plug head rushing off.
