防渗膜在埋地LPG储罐阴极保护的应用OA

This study proposes a sacrificial anode cathodic protection method for buried LPG storage tanks integrated with an impermeable membrane,ana-lyzing its technical feasibility,construction complexity,and economic viability,supported by practical case studies.The impermeable membrane,an effective elec-trical insulator,is installed along the inner walls of the tank pit for buried LPG storage tanks to prevent cathodic protection current from leaking into the sur-rounding soil or grounding grids.This method signifi-cantly reduces current leakage,extends the service life of the sacrificial anodes,and offers advantages such as straightforward installation and cost controllability.
