EMI1.1
Es ist bekannt, dass Eisen ein Schutzmittel für Kupfer und Kupferlegierungen gegen die zerstörende Einwirkung des Seowassers bildet Man wendet dabei den Eisenschutz in Form von Eisenspiralen, Drahtuetzen und dgl Drahtgebilden an, die zur Herstellung gut leitender Verbindung an die zu schützenden Flächen dicht angelegt werden. Das Eisen scheidet infolge der entstehenden eluktrolytischen Wirkung kräftig Eisenoxyd ab und es bildet sich nach einiger Zeit auf der Kupferfläche eine Eisenoxydschicht, welzhe die Kupferfläche isoliert und so ais Schutzschicht für dieselbe wirkt (s. Ö. P. Nr. 21795 und 26004 sowie Zeitschrift des nVereines deutscher Ingenieure", Jahrgang 1905, Seite 735).
Die Eisenspiralen, Drahtnetze und anderen Drahtgebilde lassen sich mit der zu schützenden Schicht nicht durchaus fest verbinden, verringern den freien Strömung- querschnitt bei Rohrleitungen erheblich, schlitzen nur lokal, lassen sich schwer einbringen und ersetzen und verstopfen durch Abbröckeln in grösseren Stücken die Absperrorgane, wodurch die Betriebssicherheit gefährdet wird.

EMI1.1
It is known that iron forms a protective agent for copper and copper alloys against the destructive effects of the seawater. Iron protection is used in the form of iron spirals, wire meshes and similar wire structures that are tightly attached to the surfaces to be protected to create a conductive connection. As a result of the resulting eluctrolytic effect, the iron separates vigorously iron oxide and after some time an iron oxide layer forms on the copper surface, which isolates the copper surface and thus acts as a protective layer for the same (see Ö.P. No. 21795 and 26004 as well as the magazine des nVereines deutscher Ingenieure ", born 1905, page 735).
The iron spirals, wire nets and other wire structures cannot be firmly connected to the layer to be protected, reduce the free flow cross-section in pipelines considerably, only slit locally, are difficult to insert and replace and clog the shut-off devices by crumbling off in larger pieces, thereby operational safety is endangered. If they get into the machine, they can

Wire nets and the like. Wire structures form a more uniform coverage of the surfaces to be protected than the spirals with their easily movable turns, but are not generally used for this purpose, e.g.

Can be found.
The sheet metal sleeves reinforced in this way are either used directly or pipes can be manufactured from them in the usual way. The finished pipes can also be supplied already finished oxydurt by the manufacturer, so that there is no risk of iron oxide contamination of the water after installation. As experiments have shown, the iron or steel chips adhere extremely firmly to the
