Industrial Breakaway Couplings
Industrial Breakaway Couplings are typically installed onto Loading arms and hose assemblies where at least one side is attached to a fixed point. Industrial Breakaway couplings are used to prevent pull-away accidents, protect terminal and loading/unloading equipment and eliminate unwanted product release. The breakaway couplings have a diverted breaking point which will break at a determined break-load whereupon the internal valves will automatically close the valves on both sides hence the flow ceases. This will minimize down time, and save money, equipment and the environment.

EWFM Specialise in Swivel Joints, Loading and Unloading Arms, Couplings, Breakaway Couplings, Filling and Emptying Equipment, Hose, Agitators and Mixers, Access Systems, Storage Tank Equipment, and Aircraft and Helicopter Equipment for the Oil & Gas, Food and Drink, Chemical, Pharmaceutical, Power Generation and the Defensive and Aviation Industries.
Main Features
Operates independently of shut-off safety systems and furthermore does not require any external power sources.
These are also easy to reset on-site by one person with minimal tools and training.
In addition to the above they have a very high flow rate / low pressure drop.
Connections
ANSI or Din Flanged
BSP or NPT Threaded
Victaulic connection
Combinations of the above can also be achieved
Sizes
1? to 12?
Materials
Aluminium or Stainless Steel
Seal Materials
FKM, EPDM, FFKM and NBR
Applications
The Industrial Breakaway couplings can be use in a wide range of applications such as:
LPG, Butane, Propane, CO2 and LNG.
They can be also used for Diesel, Acids, Jet A1, Alcohols, bulk loading and un-loading, road tankers and process product transfer.
Working Pressures
16 to 25 Bar (150psi to 300psi) 40 Bar / 600 psi versions available on request.
Safety Breakaway Couplings are used to prevent pull away accidents, protect terminal and loading/unloading equipment and eliminated unwanted product release. The breakaway couplings have a predefined breaking point which will break at a determined break-load where upon the internal valves will automatically close flow on both sides.
Safety Breakaway Couplings (Emergency Release Couplings) with integrated shut-off valves are used to avoid spillage and damage associated with drive and/or pull away incidents when loading and unloading. The couplings are designed to be the weakest link of the hose line or loading arm. This will in a longer time frame minimize down time, save the environment, equipment and the investment. Safety Breakaway Couplings are suitable for a wide range of products including petroleum-based products, chemicals, gases and foodstuffs.
Available in breaking pin version (marine type and industrial type) and cable release version.
Safety Breakaway Couplings for Industrial Applications
Typically installed between a fixed point and a hose line, breakaway couplings prevent the risk of spills, protect your installation and ensure operator safety on a broad range of applications requiring a secure fluid transfer.
This range offers a high flow rate and two types of separation mechanisms to meet the needs of numerous industries including chemical, petrochemical, railway…
Separation occurs when force is applied axial or up to 90° (any direction) to the plane of the coupling and safety is provided thanks to an instantaneous closure of both flows.
The Breakaway Coupling acts as an identified safe parting point in a hose or loading arm product transfer line, separating in the event of excessive forces being applied, and provides an instantaneous mechanical positive closedown, therefore eliminating from both sides involved, the possibility of human danger, explosion, fire or environmental pollution damage.
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 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.
Breakaway Coupling. This actuates when sufficient side load is imposed on three radial break studs on the coupler. Once the first (waisted) stud is stretched, the internal poppets will close before the seal is breached and then the two halves of the coupler will part. The result is an almost zero displacement of liquid. The key to success in this type of coupler comes from the shear angle being in the optimum range to allow the studs to break cleanly. If it is a direct pull force, because of positioning, the arm could fail first.
Emergency Release Coupling. Essentially the same internal design, but the two halves of the coupler are held together by a clamp, wihich, in turn, is held together by a system with a break pin. The pin is connected to a Bowden cable and that is fixed to a bracket that tracks the rotation of a loading arm swivel. A pre-determined range of movement is set up and if the arm is pulled outside of that range, the cable will break the pin and the clamp will open. Releasing the two halves and closing the poppets.
