Titanium Steam Coil: Important Galvanic Risk in Anodic Tanks

Summary for titanium steam coil Discussion

Titanium steam coil in lead lined anodic tank is the core concern here: Mark Lees asks whether a titanium steam coil touching the tank in a live anodising bath could create galvanic effects in 15% v/v sulfuric acid at about 20 °C. He explains that a previous lead-clad steel steam pipe cracked, letting steam into the tank and forcing a major cleanup and tank removal. No answer text is included in the excerpt, so the thread provides only the question and the operating conditions, not a confirmed solution. The practical issue is whether titanium is compatible with the lead-lined, electrically live environment and whether direct contact with the tank in solution should be avoided or isolated.
