Static electricity problems in pipelines of flammable and explosive chemicals
The hazard of static electricity is a major security threat to units using flammable and explosive chemicals, and the state attaches great importance to the prevention of static electricity. Non-metallic pipes such as rubber and plastic pipes are more likely to generate static electricity than metal pipes. Therefore, units using plastic lined pipes should consider the static electricity problem of such pipes. Especially when transporting non-conductive fluids such as toluene, xylene, the build-up of static charge creates the potential for sparks, so any build-up of static electricity inside the pipe must be considered.
One is grounding, which is to guide static electricity to the ground; the other is electrostatic shielding, which is to use electrostatic shielding to weaken the influence of external static electricity on components; the third is ion neutralization, which is to use ions of opposite polarity to neutralize static electricity. Use these three methods to continuously introduce electrostatic charge into the ground, shield or neutralize it, and control the electrostatic potential within a safe range. This is a preventive approach.
