Filiform Corrosion - an overview ScienceDirect Topics

Filiform corrosion is a variation of a differential aeration cell. A filiform track has an active head, which is deaerated and acidic, and a filamentous tail, which is aerated and alkaline. Separation of anode and cathode is essential for filiform corrosion to occur. As the filiform track proceeds, the coating and metal are disbonded and the sp.info [DOC]HRSD HRSD · Web viewThermite welds to ductile pipe shall be coated with a minimum of 10-mils of a brush-applied mastic.
