The energy contained within a pressure hose, in case of disconnection from the fitting, can be very dangerous to anyone or anything in its vicinity.
The patented system STOPFLEX of OP srl, has been designed to arrest the trajectory of the flexible hose, thus avoiding that the energy contained inside may trigger a frightening "whip effect".
The cable secures the hose to the plant protecting both the operators and components.
The bend, equipped with a rubber gasket, remains perfectly secured, simultaneously allowing the hose to swell according to the working pressure, avoiding dangerous oil splashes and breakages.
How does it work?
The Stopflex system does not operate during the step of disengaging the flexible hose, but, if properly applied, it ensures that the hose is fully disengaged from the ferrule that restrains it.
During the release step, the hose gains considerable velocity.
Once the hose has been disengaged and the pressure released, the flexible hose can be restrained. This is where the Stopflex system gets into operation: the stainless steel cable is tensioned and deformed while the plate cuts into the rubber of the hose, preventing the clamp, firmly attached to the hose, from disengaging. The hose clamp and plate start to deform in turn, elastically absorbing the force released from the travel of the flexible hose.
