The electrification process of the materials and technical equipment-s, especially the external parts of them, frequently occur during their use, being sometimes an intrinsic process, such as for example flowing of a flammable liquid through a pipe. The electrification process of materials and technical equipment-s is responsible for generating, through specific mechanisms, significant quantities of electrostatic charges. The presence of electrostatic charges on materials and technical equipment-s, used in areas w...

Flammable liquids in motion when is transporting by pipes, is mixing, pumping, filtering, agitating or by pouring them from one vessel to another can generate static charges even if the respective pipes or vessels are bonded and earthed. Also, loads may occur if the liquid is splashes and forms a mist inside the vessel (tank, container). Accumulation of static electricity can, under certain conditions, be discharge and ignite the explosive atmosphere. In the paper are presented some aspects regarding the technical...
