2 Type of Marine Breakaway Coupling that Usually Used
In the last few decades, marine pollution from oil spills has become a very serious problem. The impact of pollution can be seen from the number of marine living creatures that died from oil spills. The birds that used to swim at sea level, their whole body covered by oil and to clean it they must lick the contaminated fur. In the long run, the birds will lose their appetite and die. To help overcome this, MBC is made as hardware in oil hose transfer lines.
The working system of MBC is to stop the flow of oil when the oil transfer hose is cut off. MBC is claimed to be able to reduce oil leak during the transfer process. MBC is passive, so it does not require power to operate, no need to monitor continuously to find problems, and no operator action is required.
MBC is made for endurance for fifteen to twenty years. For that, it is necessary to pay attention to the components needed when you want to install MBC so that the specifications appropriate and as needed. In choosing MBC, need to be analyzed carefully, because this device is not included cheap. Of course, you do not want to be disappointed after installing MBC because it does not suit your needs. If necessary, you can consult the MBC manufacturer to find out what model is required.
Although there are many variations on MBC, there are two main types that are usually recommended by the manufacturer. This selection is certainly tailored to the type of fluid being transferred and other parameters. The first type is the Petal Valve Type MBCs. This type is designed with full-sized holes and is suitable for higher viscosity liquids, one of which is crude oil. The benefits offered by this type of MBC are fully piggable and have zero headloss.
The second type is the Flip-Flap Type MBCs. In this type does show some headloss though still at a very low level. This type is more suited to low viscosity liquids such as kerosene and petroleum gas liquid.
