A bund is a structure designed to stop flooding no matter what the source is. These can be used as a protection in warfare, to provide further defence to soldiers.
Moreover, a containment bund can also serve as a control system that restricts any spilt material from its primary container to a particular space that can be contained.
Here are more pieces of information about them.
Functions during Spillage
In general, containment bunds are low walls that stop leaking tanks and pipes from getting to wider areas. This is quite beneficial when the liquid stored is actually toxic and in situations where spills can cause losses.
These bunds function as walls that confine the spilt liquid from flowing. It can even aid in its retrieval if necessary. You can typically find these around massive storage tanks. Otherwise, these run along the pipes utilised to transport or store flammable or toxic liquids.
You can also find these set up around vessels or reactors used for reaction and processing. This way, the material will still be contained in a defined space in case of possible leakage and damage. These can even be utilised for refrigerated gases, but not as much for gases kept under pressure.
People usually define tank farm sizes by the ability of the bunds to restrict liquids kept in an area. Manufacturers recommend using varied bunds in situations where tanks already hold plenty of diverse materials.
The majority of bund capacities carry 110 percent of the capacity of the biggest tank. And manufacturers designed and made them to be effective in their function, and the rate of constructing this is quite reasonable.
Containments bunds have varied functions, purposes and capabilities. With the info above, you will be able to determine if it is perfect for your particular usage.
