Break-aways
MannTek Safety Break-away Couplings - Marine Version
Application:
•
typically for ship-to-offshore platform and ship-to-ship product transfer operations
Features:
• designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
•
minimizes spillage and damage associated with pull-away incidents
•
coupling automatically senses excessive load, closes the valves and disconnects, release is executed when force causes bolts
to break
•
working pressure:
360 PSI
at ambient temperature
70°F (21°C)
•
FKM (FPM) O-rings, additional seal materials are available
•
optional non-closure design available, contact Dixon

How it Works
Safety break-away couplings have three external break bolts. In the case of axial tension all of the bolts take up the force
corresponding to the break force on the hose with a safety margin. Non-axial forces concentrate the tension forces more strongly
on one bolt, so that the safety break-away coupling reacts in a natural way to the reduction of the hose break forces.
The safety break-away valve consists of two halves, each with
a valve that has a O-ring seal.
BEFORE emergency disconnect
When the safety break-away couplings separate, it allows
the valves to close. The two valves close rapidly, minimizing
exposure to personnel and the environment.
