Dielectric bushings are essential components for STI-P3 tanks, which are double-walled, corrosion-resistant underground storage tanks made from fiberglass and steel. These bushings are designed to prevent electrical current from passing through the tank system, which is crucial for minimizing the risk of corrosion and ensuring the longevity of the tank.
Since STI-P3 tanks are often installed in environments where the risk of electrical interference is significant, using dielectric bushings in all openings helps protect the integrity of the tank against stray currents. This is especially important at the point of entry for piping and wiring, as these areas can be susceptible to electrical faults.
The requirement for dielectric bushings in all openings aligns with best practices in tank installation and maintenance, promoting safety and compliance with regulatory standards. By using dielectric bushings universally in all openings, operators can ensure optimal protection for their storage tank systems, which is a critical aspect of UST management.
