This sounds a bit of a nightmare to me. AN EJ in the jacket and the core ??
I guess you are dealing with a highly viscous or solidifying fluid in the core. What will happen if the core cools, solidifies and sticks in the EJ convolutions. Then you up the heating in the jacket. The jacket will expand and the internal bellows may tear. What about initial testing / inspection of welds and convolutions ? And the need for regular inspection of the internal EJ ?
There are jacket heated, flanged flexible hoses on the market, I've seen them used in sulphur service. Worth a thought ?
Dear All,
Which one do you think work best in case of jacketed sulphur line:
EXJ or Flexible hose?
I beleive a flexible hose can handle it better as there is no convolutions inside it.
My system consists of a header and 5 branches. I think of 2 possibilities as follows:
1- Using EXJ on stright header to reduce longitudinal expansion so that I won't need much flexibility on branches.
2- Uning flexible joints on branches to handle the stright header expansion.
Please advise me if you have any points regarding this and also let me know your ideas about jacketing a flexible joint?
By the way how do you model a flesible hose in CAESARII?
