An engineer was seriously burned when a thirty-nine inch expansion joint ruptured while workman were performing temporary repairs at a Texas refinery. The ruptured bellows spilled hot catalyst from a fluidizer catalytic cracking unit on the deck – on which the engineer had to cross to reach safety.

We were asked to perform a failure analysis on the bellows. We determined that:

  1. The stainless steel had not been heat-treated properly
  2. The steel was sensitized during fabrication and made susceptible to corrosive attack

 

We perform failure analysis on equipment for clients in industries including energy, mining and petrochemical. Give us a call to discuss your engineering challenges.
