Cathodic Protection electrode structure of buried piping

摘要

(57) Abstract Objective The corrosion-proof device of external power source mode is used for embedding pipe arrangementBe able to do ru thing, maintaining, inspecting and taking the electrode of the long-term use timeChanging job to become easy, decrease of conservative expense and compaction of term of worksTemporary offer the electric anticorrosion electrode structure of the embedding pipe arrangement which is obtained. Constitution In the electric anticorrosion electrode structure of embedding pipe arrangement, embeddingOutside was welded in the opening which is provided in the wall of pipe arrangement 1 flange 4With, on pipe arrangement side of outside flange 4 it was installed with volt/bolt 7The inside flange to penetrate completely 6 and the inside flange 6, the inside flange 6Insulating, the lead line terminal area 8 which is provided and lead line jointThe electrode 10 which is installed on the inside flange side of section 8 and riSlack one end is jointed to the outside flange side of do wire jointing section 8Way the lead line 13 which, it has and lead line 13 is enclosed outside huTo be installed in ranji 4, at the same time in the other end of lead line 13 connectionThe cover 17 where you can install the connector 14 which continuation is done and,The embedding which connector 14 and terrestrial power source equipment it continues jointsIt features that it has buru 18.
