Marine Breakaway Couplings

  • Alpha Process Controls International has over 35 years’ experience in the design and manufacture of safety breakaway couplings. Alpha's range of marine breakaway couplings provides safety critical protection from spillage when ships or barges are transferring hazardous cargoes to shore.

    APC's stainless steel marine breakaway couplings come in sizes from 4" to 8" with a wide range of seal trims available to suit specific applications.

    Features of the APC marine breakaway couplings include a unique, simple inbuilt damping system to reduce the effects of pressure spikes, should the coupling be called upon to separate during full flow transfer. The couplings can also be easily reassembled after a drift-away incident.

    With a proven track record in the field, our customers have the peace of mind that comes with knowing that their risk of product spillage in harbours and ports is reduced by installation of these couplings.

  • Reliable operation
    The simple design of the coupling ensures reliable operation even in the most demanding operations.

    Pressure spikes damped
    Damped positive shut-off during coupling shutdown reduces effects of pressure spikes at high flow rates.

    Proven design
    Over 30 years field experience.

    Unique design break bolts
    Break bolts designed to prevent easy substitution of a standard nut and bolt, providing increased safety.

    Supplied to major oil, gas and petrochemical companies throughout the world.

    Rigorously tested
    Hydrostatic testing for each individual coupling.
