Protection of fuel storages with floating roof from static electricity

Protection of fuel storages with floating roof from static electricity

When storing fuels and lubricants, a major problem is expansion and contraction of the fluid depending on the temperature of the environment. In case when a storage represents itself a rigid metal tank, then some space filled with air is left in it so that, due to compression-expansion, there is no deformation of the container. Fuel and lubricants evaporate into this space. When the storage is ...
