<p>PURPOSE:To reduce the corrosion protective current by a structure wherein the inner surfaces at inlet and outlet ends of titanium tubes are insulated. CONSTITUTION:The inner surfaces at the inlet and outlet ends of the titanium tubes 5A extending over a proper length are coated with an electric insulating material 12. Concretely, thin tube made of nylon or polyethylene is adhered by a bonding material such as epoxide resin adhesive or the like. Owing to the structure as mentioned above, the current consumed within the titanium tubes 5A is reduced and as well as the restriction of the kind of the electrode suitable for the corrosion protective current can be eliminated.</p> |
