Yesterday only we visited the plant and found that 3 more tubes are leaking. These leakage is just nearby existing tubes. Iam attaching sketch of the tube layout for your reference. These new leakages are all at a height of ~1 feet from top. Problem found is again erosion of tubes. This time I...

We have this heat exchanger installed in our plant. There are two modules. In module-2 saturated steam is entering @200 Deg C and heating the air from 40 to 80 Deg C. Condensate from module-2 is given to module-1 which preheats the air entering in module-2 from ambient temp (30 Deg C) by 10 Deg...
