Does anyone have experience or data on steam jacketed carbon steel rundown lines for molten sulfur? In particular, have you identified a predictable failure mechanism in the piping, either in the steam side or the sulfur side? Do you have an assumed/ measured corrosion rate? What proactive means to do you employ to keep the line from failing? If anyone has an active reliabiltiy strategy and is willing to share it, it would be a great help. This seems to be one of those failures whose consequence is enormous by probability is slim. Thoughts?
