Pipeline corrosion control cathodic protection use prepacked magnesium alloy anode

Environment-friendly
Bare Mg anodes are assembled with cable and the joints aresealed with epoxy resin, packed in cotton bag and filled withbackfill
Prepackaged anodes are buried under the ground, backfill ofprepackaged anode will escape to the earth and groundwater,therefore any harmful element inside the backfill will pollute theenvironment
Made of recyclable materials or easily decomposable materialsand the content of harmful elements in the backfill is lower thanany safety standards
Available cable types (insulation/sheath):
PVC/PVC, XLPE/PVC, HMWPE with cable size: 4, 6, 10 and16mm²
