If a simple bellows is designed without limit rods (for operating cases), under a hydro test, do you recommend adding limit rods?
|Yes, if they are testing just the expansion joint or if they are testing when installed, they have to make sure that the pipe line is anchored or have limit rods added to the expansion joint to absorb the pressure thrust.
