Expansion Joints are provided on the shell side of the heat exchanger. It allows the free expansion of shell relieving tubesheet & tube to tubesheet weld junction. Thus preventing its failure.
Process equipment manufacturer from India & Abroad approached ANALYZER to seek assistance in evaluating the design of their newly developed heat exchangers for their expansion joint & provide the solution in case of any observed failure.
The expansion joint was analyzed for different loading conditions as per TEMA standards using Finite Element Analysis in ANSYS APDL Solver. Stress Linearization has been carried out at various locations as per the guidelines. The results showed that the induced stresses were well within the acceptable limits. Hence, the structure’s design was predicted to behave safely during operation without premature failure.
