Impressed current cathodic protection design, materials, installation and commissioning for a sub-floor stainless steel lube oil drain line encased in controlled low strength material (CLSM). UTRS designed an impressed current linear anode system considering the chromium oxide passivating layer of stainless steel, the high pH environment of CLSM, and possible interference with sub-floor supporting structures. UTRS installed anodes, wiring, test ports, and a rectifier inside the maintenance building.
