Why does the tanker always drag a "tail of iron" that can carry electricity?
Thus, the oil tank will not burn or even explode due to electrostatic sparks
In the same way, the flow of oil in and around the tank will also rub against the tank walls and produce static electricityThe purpose of the iron tail is to move the static electricity as soon as possible, and pour it into the earth
We all know that friction causes sparks, sparks, especially in the winter evenings when we strip
The tanker carries oil that is flammableIt's not just open flames that make the oil burn, it's probably static sparks
