Application area

Shallow magnetite groundbed Mendeleevets–MTP / Mendeleevets- MPP are meant to be used 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

Shallow magnetite grounbed is an electrode with a corrosion-proof cable 2 m length.

Magnetite electrode of tube form is used as a working element. A contact between a cable and an internal surface of the electrode is carried out by means of a contact spring. For isolation of contact junction a specially developed chemically resistant solution on the basis of polymeric compound is used. An additional isolation of the place of cable outlet is made by 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 control equipment by means of main cable. Joining of an anodic cable to the main 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.
