Q. What is a safety breakaway coupling?

A. A safety breakaway coupling comprises two half couplings that are held together with shear break bolts to form a leak tight coupling. The breakaway coupling is installed between the terminal pipework and the flexible loading hose. The safety breakaway coupling is designed to be the weak-link in the system so that in the event that the road, rail tanker or ship moves off while still connected the coupling separates and instantly shuts down the flow. The safety breakaway coupling is used in an emergency only and is not normally connected or disconnected in the course of normal use.
