![]() “If you’re at a site in Florida, for instance, and you’re dealing with an ambient temperature of nearly 100-degrees Fahrenheit and then within minutes you start pumping a liquid at a temperature of -260 degrees Fahrenheit, the breakaway needs to be able to survive that extreme change,” says Andersen. The breakaways are constructed from 316L stainless steel and fitted with specialized PTFE (Teflon™) seals, which can handle the extreme cold as well as drastic changes in temperature. The marine breakaway is designed not to respond to the normal rocking of the boat on the waves, but if the boat were to start drifting away from the platform in a horizontal direction, stressing the hose, the breakaway would activate, protecting the assembly while the stopping the flow of liquid.Ĭryogenic breakaways are based on industrial breakaway designs but are specifically made to handle ultra-cold cryogenic fluids, such as liquid nitrogen, oxygen, and liquid natural gas (LNG). You’ll usually find marine breakaways employed on offshore oil platforms, in line between the platform and hose to the supply vessel, pumping fuel, drilling mud, or chemicals for the operation. Marine breakaways, on the other hand, only release at a straight pull-not at an angular pull-and are installed between two runs of hose. They are designed to release at any angle from 0 to 90 degrees and are always installed to a fixed point. Industrial breakaway couplings are by far the most common and can be used in myriad different applications. Three of the most common types of breakaway couplings include industrial, marine, and cryogenic. Where else do you typically find breakaway couplings? At the same time, a poppet valve within the coupling, automatically seals off the system, preventing a spill and potential fire from the spilled gasoline. What would happen at a gas station if a driver unexpectedly pulled away from the pump without disconnecting the fill nozzle? A breakaway coupling ensures that damage to the gas pump remains minimal. Its function is primarily to protect the hose and the piping from more permanent damage.”īreakaway couplings are used in a variety of industrial, marine, and even consumer-oriented applications. “They are designed to separate when either a force load is applied to it or when a hose reaches its end of travel. “They are essentially an engineered fail point,” says Sean Andersen, a product manager at Dixon. ![]() They protect terminal and loading/unloading equipment and eliminate unwanted product release. Breakaway couplings are used to minimize damage associated with pull-away accidents. And that’s where a breakaway coupling comes in. Under many circumstances, you wouldn’t want a hose to suddenly detach from its connection. Hose couplings are designed to keep connections secure. ![]()
