The problem of internal electrical discharges and the subsequent ignition of the vapours inside tanks containing flammable or combustible liquids is becoming more widespread as the use of non-metal and lined tanks proliferates. These types of tanks are often used to store highly corrosive substances, therefore the tanks are often made of either corrosion resistant materials, such as fibreglass or PVC, or internally-lined steel, where the lining is a non-conductive material such as epoxy.
During normal operation, the tanks accumulate flammable or combustible vapors inside the tank above the fluid level. These vapors may then be ignited by an electrical discharge inside of the tank. The discharge can be caused by an accumulation of static electricity inside the tank or by a direct or nearby lightning strike.
The IPE is made specifically for non-metal and lined tanks. When the IPE is inserted into a tank and externally grounded, it will discharge any static electricity within the tank’s contents and also keep the potential of the tank’s contents equal to ground potential.
- Anchored design: maximises surface exposure and minimises movement
