| Abstract: | Anodic protection ot titanium in the rayon industry A shell and tube exchanger of Ti for preheating spinning baths (47 to 75°C) is operating under an anodic protection potential of 10 to 15 V during two years' operation no measurable thinning has been found. In this connection it is important to prevent crevice corrosion, either by suitable design or by using a tube plate of Ti with 0,2% Pd. Proto-types of exchangers have been used to establish the throwing power of electrodes mounted at different points in the equipment. |
