Reliance industries had experienced problem of leakages of tubes and tube to tube sheet joint (TTSJ) in E-699 and E-555 propylene condensers. These condensers are shell and tube type heat exchangers. E-699 is used for condensation of propylene, which is further used as refrigerant in various systems. Recommendations were given to minimize these leakages and consequently increasing the efficiency of condenser.
