  • Abstract:
  • Bellows are one of the most efficient energy absorbing elements for engineering system. Bellows have a function to absorb regular or irregular expansion and contraction in piping system. Bellows are special structures that require high strength as well as good flexibility. The failure of bellows expansion joints made of SS 304 has been analyzed. Over pressure, Vibration of steam in piping are responsible for the failure. After complete observation of the bellows we found that wrong design data are assumed at the time of bellows manufacturing and finally these bellows are fail within 1 year of service. Based on these design data we have improve the design and its re-design the metal expansion bellows by using EJMA code and FEA simulation. To prevent the bellows failure chances we have provide internal liner in the bellows which has many advantages such as: to ensure smooth flow of media, minimize friction losses, minimize resonant vibration caused by high flow velocity, reduce the effect of turbulent flow upstream of the expansion joint, prevent erosion of the bellows wall from chemical and abrasive attack, reduce the temperature of the bellows in high temperature application. In this work A finite element analysis (FEA) of bellows proposed.
