Method for providing cathodic protection to underground metallic structure using galvanic anodes

摘要: A method of providing cathodic protection to underground metallic structures which comprises creating an excavation spaced from the structure and placing in a hollow casing having perforate section, being adapted hold therein galvanic anode. The further establishing electrical connection between anode structure, then filling with filler material. apparatus invention rigid contain at least one anode, section such that electric current can flow out towards structure. related replacing anodes is also provided.
