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.
