PROBLEM TO BE SOLVED: To provide an electric corrosion protection structure preventing crevice corrosion between piping flanges. SOLUTION: The electric corrosion protection structure for piping flanges is composed in such a manner that wiry, strip or ring this sheet-shaped insoluble anode is inserted into the space between the mutual joined faces of each piping flange made of stainless steel, each piping flange made of Ni base alloy or a piping flange made of stainless steel and a piping flange made of Ni base alloy by clipping wiry, strip, or ring thin sheet-shaped insoluble amode with a ring plate shaped insulating gastet and is insulated from the piping flange, and furthermore, the inside edge part is exposed to the inside face of the piping and fitted thereto. |
