RE: Failure of heat exchanger twisted tubes
If twisted Hx tubing you mean damage caused by a circumferential rupture or failure where the tube whips around. This this could be caused by mechanical fatigue, stress corrosion cracking, fretting, etc.

I consider that the biggest factor for not using a twisted tube. If you have a process and MOC combination you know does not corrode the tube, then a twisted tube exchanger can be a suitable method to get more heat transfer out of a smaller foot print.
