Definitions
- the invention relates to the field of electrochemical protection, namely to corrosion protection of underground and underwater metal pipelines and structures.
- electrochemical (cathodic) protection the basis of which is the anode [1, 2, 3, 4, 5].
- An analysis of the reasons for the failure of electrochemical protection plants indicates that most failures occur due to damage to their anodes.
- Anodes are the most critical element of the cathodic protection system, therefore their reliability is one of the determining factors in the reliability of electrochemical protection as a whole.
- a metal anode was adopted as an analog.
- a relatively large mass of electrodes for example, 1 pc. EGT 2500 "weighs 19.2 kg. For anodes operating under a current of 50 Amps for 10 years, their need is ⁇ 25 pieces. Their total weight is 480 kg).
- thermostyrene which is used as a heat insulating material [7].
- the objective of this utility model is to use a well-known product, namely flexible thermally expanded graphite as a material for an anode with a long shelf life.
- SUBSTITUTE SHEET (RULE 26) The task is achieved by using flexible thermally expanded graphite (thermogrenite) as the anode body, which provides the anode with properties that distinguish the proposed anode from analogues:
- the total mass of a flexible thermally expanded graphite sheet rolled 1 mm thick is 25 kg;
- Thermographit is produced in the form of flexible sheets, foil, tape, and other products. This entire class of materials, regardless of shape, is suitable for the manufacture of anodes.
- the anode of a flexible graphite sheet - rolled (thermally expanded) graphite (thermogenite) can be used in any soil, as well as for the cathodic protection of offshore structures. It is also possible to use the anode from Thermogrenite as grounding for power consumers, direct and alternating current power lines, lightning rods and earth drainage devices. Assembled into a single unit, in an extended design, the anodes under the action of soil movement bend at large boundaries and maintain their operability.
