Abstract

PURPOSE: To increase the anticorrosion effect, by winding the joint area or the whole part of the galvanized steel pipe buried under the ground with the zinc long-sized flat bar or wire rod having a lower potential than the steel material.
CONSTITUTION: The area where the galvanized steel pipes 1 is connected with the zinc galvanizing joint 2 is wound over with the zinc long-sized flat bar or wire rod 13 made of the metallic component having negative potential. Thus the partial current flows in the direction of the arrow 12 by the potential difference among the zinc galvanized area of the pipe 1 and joint 2 each and the exposed area 14 of the steel material due to the welding connection and the screw at the joint area each. Thus the galvanized layer elutes to give protection to the steel material with electric anticorrosion.
