Abstract
Sacrificial anodes for installing in an ionically conductive medium at an installation site containing metal requiring cathodic protection are formed by locating anode cores in a tray having dividing members defining a row of side by side chambers with each chamber containing a respective one of the anode cores and casting into the receptacle a covering mortar for the anode cores with each anode core receiving a coating at least partly surrounding the anode core with the connecting wire exposed. The mortar is cast to form frangible bridges between each anode and the next. The trays are stacked and transported to the site where the installer separates and individually installs the anodes into the medium.
Claims24
A method for forming sacrificial anodes for installation in an ionically conductive medium at an installation site which medium contains metal requiring cathodic protection comprising:
- locating in a receptacle a plurality of anode bodies each comprising a sacrificial material and at least one connecting component for use in making an electrical connection between the anode body and the metal;
- providing in the receptacle dividing members defining a plurality of chambers with each chamber containing a respective one of the anode bodies;
- and casting into the receptacle a covering material such that the covering material is in contact with at least a portion of each anode body.
A method for forming sacrificial anodes for installation in an ionically conductive medium at an installation site which medium contains metal requiring cathodic protection comprising:
- locating in a casting receptacle at least one anode body comprising a sacrificial material and at least one connecting component for use in making an electrical connection between the anode body and the metal;
- the casting receptacle comprising walls defining at least one chamber;
- inserting said at least one anode body into a respective one of said at least one chamber of said casting receptacle;
- supporting said at least one anode body in said respective one of said at least one chamber of said casting receptacle so as to define a casting space between at least one of said walls and a surface of said at least one anode body;
- casting into the casting space in the receptacle a covering material such that the covering material is in contact with at least said surface of said at least one anode body and such that the covering material is confined and shaped by said at least one wall of the casting receptacle;
- and, after casting, transporting for use at a remote location said at least one anode body and the covering material while said at least one anode body and the covering material remain contained in the casting receptacle;
- wherein the casting receptacle is formed of a flexible material shaped to form said at least one chamber and bendable to release the flexible material from the cast covering material.
A method for forming sacrificial anodes for installation in an ionically conductive medium at an installation site which medium contains metal requiring cathodic protection comprising:
- locating in a receptacle at least one anode body comprising a sacrificial material and at least one connecting component for use in making an electrical connection between the anode body and the metal;
- the receptacle comprising walls defining at least one chamber;
- inserting said at least one anode body into a respective one of said at least one chamber;
- supporting said at least one anode body in said respective one of said at least one chamber so as to define a space between at least one of said walls and a surface of said at least one anode body;
- casting into the space in the receptacle a covering material such that the covering material is in contact with at least said surface of said at least one anode body;
- wherein said at least one connecting component extends outwardly from the anode body;
- wherein said at least one anode body is supported and located in the receptacle during said casting by engagement of said at least one connecting component with at least one wall of said walls;
- and wherein the casting receptacle is formed of a flexible material shaped to form said at least one chamber and bendable to release the flexible material from the cast covering material.
