摘要： The deterioration of reinforced concrete structures by galvanic corrosion adversely affects roads, bridges, parking garages and buildings that use reinforcing steel in their construction. Galvanic cathodic protection is typically provided for such reinforced concrete structures using embedded sacrificial anodes, such as zinc, aluminum, and alloys thereof. Disclosed herein is an anode assembly (10) for cathodic protection of a reinforced concrete structure. The assembly comprises at least one sacrificial anode member (12). The anode member is covered with an ionically-conductive covering material (14) into which is bound an electrochemical activating agent at least partly covering the sacrificial anode member. One side (26) of the ionically-conductive covering material is configured to conform closely to a steel reinforcing bar. The conforming side has a non-conductive barrier (16) as an integral part of the covering material. Electrical connectivity is established between the anode member and a ferrous reinforcing bar (20) using conductive wires (18).

摘要： A pipeline comprising one or more pipes, the pipeline having:
one or more sacrificial anodes (20) thereon to provide cathodic protection;
one or more one-piece metallic rings (12) around at least one pipe; and one or more electrical connections (14) attached to the or each metallic ring and to at least one sacrificial anode to allow an electrical current to flow between the pipeline and one or more of the sacrificial anodes.
Because the or each metallic ring has a 'one-piece' form, it can be fitted to the pipe without welding, avoiding the problems associated with welding discussed above. A one-piece ring also has no obvious weaknesses, so that there is greater assurance of its fixing to or with the pipe, and the ring is more compliant with any working on the pipe, in particular bending, compared with sleeves or other types of long sections.
摘要翻译：一种管道，包括一个或多个管道，该管道具有：一个或多个牺牲阳极（20），用于提供阴极保护; 围绕至少一个管道的一个或多个单件金属环（12）; 以及连接到该金属环或每个金属环以及至少一个牺牲阳极的一个或多个电连接（14），以允许电流在管线与一个或多个牺牲阳极之间流动。由于该金属环或每个金属环具有“一体式”形式，因此可以将其安装到管道上而不进行焊接，从而避免了上述与焊接有关的问题。一体式环也没有明显的弱点，因此与管子的固定有更大的保证，并且与套管或其他类型的管相比，环更适合管道上的任何工作，特别是弯曲长节。

摘要： Control of lead contamination in residential water supplies is accomplished by cathodic protection of lead-containing piping and lead-containing fixtures. Specifically, a partially insulated wire (3) is inserted into lead-containing service lateral piping (2). Application 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： Apparatus, compositions and methods provide cathodic protection to a structure by placing an anode layer (10) directly between the structure (22) and its underlying foundation (30). Structures contemplated to be protected in this manner include especially very large structures such as above ground storage tanks. In one aspect of preferred embodiments, the anode layer (10) comprises sheets of at least 85 % aluminum with other alloying elements such as magnesium (0.05 to 6 %), zinc (0.1 to 8 %), indium (0.005 to 0.03 %) and tin (0.05 to 0.2 %) added for the purposes of optimizing current yield, polarization and ease of manufacturing the sheet. In another aspect of preferred embodiments, the anode layer (10) comprises at least two overlapping sheets.

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).
