    • A permanent reference electrode (10, 10-1) for the potential measurement of buried metallic structures (ST) in order to verify their state of corrosion or cathodic protection including:
      - a zinc element or electrode (11) of elongated shape;
      - a special filling material (12) or backfill, based on gypsum, bentonite, cellulose fibre, sodium chloride and water, surrounding the zinc electrode (11);
      - a containment body (13) created around the backfill (12) and made of cementitious mortar (13') enriched with chloride ions; and
      - an external element or case (14), made of plastic material, that covers the cementitious containment body (13) and serve as the electrode case (10);
      where the cementitious mortar (13') of the containment body (13), in a respective area left uncovered by the outer casing (14), constitute the electrolyte contact with the ground (T) where the zinc reference electrode (10, 10-1) is buried, in a permanent way in proximity of the buried metallic structures (ST), of which the electrochemical potential is measured compared to the same reference electrode (10, 10-1).
      In a further form of realization (10, 10-2) the zinc reference electrode does not include the cementitious containment body, but only the backfill (12) and a porous separator (19) adjacent to the last one, having a porosity likely to realize the electrolyte contact with the ground (T) where the reference electrode (10-2) is buried.
      The zinc permanent reference electrode (10, 101-1; 10-2) of the invention is usefully likely to remain active for a long period of time in soil (T) where is buried and not to be subjected to the passivation phenomenon.

    • 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.
    • 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。
