Application area

Anodes Mendeleevets-MM / Mendeleevets-FPP are meant to be applied as poorly soluble elements of shallow anode groundbeds in the sets of cathodic protection from corrosion of pipelines and other underground metal constructions. Type of groundbed disposition may be horizontal or vertical.

Technical details

silicon iron electrode;
thermocontracting coupler;
connecting cable.

Anode groundbed is an electrode made from silicon iron (corrosionresistant iron-siliceous alloy) with connecting cable. Length of the cable is 2 m in the standard option.

There are two modifications of groundbeds different in weight and dimensions: MM/FPP(23) and MM/FPP(43).

Electrodes have a core-sand mold and the molding is of circular section. In the head part of an electrode there is a contact junction filled with specially developed chemically-resistant solution on the base of polymeric compound and firmly isolated from the outside with thermocontracting couplers.

Quantity of anode groundbeds, distance between them and the type of disposition are determined by the project of cathodic protection.

Grounbeds are assembled into the electric circuit. Connection to the feeding cable of CP station is made through the monitor by means of backbone cable. Joining of anodic cable and backbone cable is carried out by using thermit welding or cord fasteners. We use thermocontracting couplers for isolation of cable joinings.

The hollow space around the anode should be filled with a coke-mineral activator (KMA) produced by Chemservice in order to reduce spreading resistance of anodic current and to slow down anodic dissolution.
