@ Habib,
Yes, I got your point. Tied bellows are meaningless when used for axial movement, they are best used for lateral movements. For me even control/limit rod is not advisable, its better to use untied bellow. Anyway, I have a 8.5 kg/sq.cm system pressure in a 20" line (imagine the thrust force), based on your experience, is it advisable to use EJ? What do you think?;)
@ Learner2011,
It's a metallic expansion joint. Any thoughts?
@ Carter,
The system has 3 pumps, and ofcourse it is combined in one system, is there something to do with EJ? interesting.
Thank you all guys. Have a nice day.
