H > Product > Metal Expansion Joint > Special Design > High Pressure Type
SummaryExpansion bellows can be designed with reinforcing or equalizing rings which are located around the outside of the convolutions, preventing bellows being forced out from high pressure. The principal purpose of these devices is to reinforce the bellows under internal high pressure, so that bellows does not squirm and equalize movement among all the convolutions.
