Dear Friend,
I again need some help. Recently i had repaired one Heat Exchanger ( Air Cooler Type). We found a problem caused by the Thermal Expansion or vibration of the tubes causing the damage of the Tube- Tubesheet weld get worn out and the Tube material has been lost about few mm at the end portion. Finally we had Plugged the tubes to avoid the problem. I have asked to write a report for this work. i do not know whether their is any format or form as per ASME or NBIC, Our company has U, S, & R Stamp.
So my dear Friends, Please help me in this problem, also if some one had any sample please give to me also. Also please suggest any other method of repairing the tubes.
Thanks to everyone.
