摘要： An apparatus for protection of metallic materials from corrosion comprising an electrical power source (5) and a conductor (7) coupled to the power source. An anode (11) is electrically coupled to the conductor. The anode is configured to be secured proximal to the metallic materials to be protected from corrosion and has an exterior surface (13) formed predominantly of electrically conductive polymer and an interior filled with particulate carbonaceous material. The anode comprises a hollow cylinder (13) formed of electrically conductive polymer, the cylinder having an interior. A metallic tube (15) is secured to and in electrical communication with the interior of the cylinder. An anode conductor (17) is electrically coupled to the metallic tube and extends from the interior of the cylinder to the exterior of the cylinder for connection to the conductor coupled to the power source.

摘要： Cathodic protection of a structure including a steel member at least partly buried in a covering layer, such as steel rebar in a concrete structure, is provided by embedding sacrificial anodes into the concrete layer at spaced positions over the layer and connecting the anodes to the rebar. Each anode is inserted into a drilled hole in the layer and is electrically attached to the rebar in the same or an adjacent hole by a steel pin which is attached to the reinforcement by arc welding or by impact. In the arrangement where the anode and the attachment are in the same hole, the pin passes through a bore in the anode so as to hold the anode rigidly within the hole. The hole is filled by a settable filler material. In order to maintain effective current conduction from the anode to the reinforcement through the filler and the concrete over an extended period to maintain the required protection, there is added to the filler, to a covering layer on the anode body or to the anode body itself a first material to hold the pH at the anode in a preferred range of the order of 12 to 14 and a second deliquescent material to absorb moisture.

摘要： Cathodic protection of an existing concrete structure, including a steel member at least partly buried, such as steel rebar, in the concrete structure, is provided by embedding anodes into a fresh concrete layer applied over an excavated patch and/or as a covering overlay. The anodes are embedded at spaced positions or as an array in the layer and connected to the rebar. A corrosion inhibitor is added into the fresh concrete at least at the interface and more preferably in admixture with the fresh concrete which acts to reduce the flow of ionic current to the steel or between the anode member and the steel in the fresh covering material without significantly increasing the resistivity of the fresh covering material and without inhibiting the ionic current between the anode member and the fresh covering material. In this way the current to the steel in the existing concrete is maximized to maximize the cathodic protection to the existing steel which is the primary target.

摘要： This invention falls into the field of devices designed to guarantee the cathodic protection, using a non consumable electrode, of tanks containing liquid, in particular boilers. A tubular element (4), which also has other functional roles within a boiler to be protected against corrosion, is made, at least partially, of titanium or a material with the equivalent anti-corrosion characteristics. The said tubular element fulfils the function of a non-consumable electrode. The surface of the said tubular element may have one or more active and passive sections.

摘要： Control of lead contamination in residential water supplies is accomplished by cathodic protection of lead-containg piping and lead-containing fixtures. Specifically, a partially insulated wire (3) is inserted into lead-containing service lateral piping (2). A pplication of a DC current to the partially insulated wire (3) causes the wire (3) to act as an anode and transforms the walls of the pipe (2) into the cathode, thereby protecting against corrosion. Alternatively, a sacrificial anode (14) is inserted into a lead-containing fixture (12). The electrical potential generated by corrosion of this sacrificial anode (14) transforms the walls of the fixture (12) into a cathode, thereby preventing corrosion. Carbonate scaling built-up prior to the initiation of cathodic protection may be removed by temporarily blocking the water pipe and introducing cleaning chemicals.

摘要： A device for treating water that circulates in a closed conduit system, said device comprising a combination of a degasifier, on the one hand, and a corrosion inhibitor, on the other hand. The degasifier includes a tubular member (10) which is horizontal in its use position and which is intended to be connected in series with a conduit (13, 14) forming part of the conduit system. The tubular member is surrounded between its upstream and downstream ends (11, 12) by a housing (17) which includes an openable upper gas outlet (16). The tubular member communicates with the surrounding housing space through the medium of at least one aperture (15) provided therein. The corrosion inhibitor includes a sacrificial anode (20) which is positioned in the housing space outside the tubular member (10). The housing (17) also includes an openable bottom drain or outlet (28).
