Safety Break-away Couplings
Safety Break-away couplings are used to prevent pull away accidents, protect terminal and loading/unloading equipment and eliminated unwanted product release.
The break-away couplings has a diverted breaking point which will break at a determined break-load where upon the internal valves will automatically close on both sides.
This will in a longer time frame minimize down time, save money, equipment and the environment.
The Safety Break-away couplings are available as Industrial and Marine type.
Industrial Break-away coupling :
Industrial Break-away coupling is utilized all industrial product transfer installations.
The industrial Safety Break-away Couplings are specifically designed to be able to activate with a tensile force being applied at an angle to the plane of the coupling housing, up to 90 degrees.
Typically installed into loading arm and hose assemblies, where at least one side of the coupling is attached to a rig and fixed point.

Marine Safety Break-away Couplings :
Marine version of SB Couplings are designed specifically to be installed within a hose string, where the coupling would have a length of hose attached to both sides.
This coupling incorporates the same internal mechanism as our Industrial couplings, but has additional external features that provide increased resistance to torsional and bending moment forces which may be applied to the coupling, preventing premature activation in the unpredictable marine environment.
Typical applications include ship to offshore platform, and ship to ship product transfer opertations.
Marine Safety Break-aways are designed to only release by inline pull and used between two strings of hose.
Release by inline pull only.
