Ferrosilicon anode grounding devices of the PAZ.KMG.F type are available with a 2-m cable lead. A key feature is the protective casing, which keeps the backfill inside the grounding device. The backfill containing the activator is evenly distributed along the entire length of the active element.

Uniform and controlled distribution of the backfill ensures effective operation of the anode grounding device and its surface grounding function.

The casing facilitates safe transportation and installation of ferrosilicon anode grounding devices of the PAZ.KMG.F type. It also contributes to the distribution of anode current from the surface of the active element. The design includes a mounting handle.

Application

Complete ferrosilicon anode grounding devices of the PAZ.KMG.F type are used in highly aggressive soils. They exhibit high chemical resistance and corrosion resistance, allowing them to maintain their properties over extended periods. They are suitable for installations requiring durability and operational stability.

During the operation of deep anode grounding systems, electrochemical reactions occur and lead to gas formation. To prevent gas accumulation and maintain operability of the element, gas removal must be ensured.

A gas vent tube is used for this purpose. It is manufactured from material resistant to reaction products of anode dissolution and to harsh operating conditions, including groundwater, brines, and weak acidic or alkaline solutions.

The customer’s technical specification determines the required number of active electrodes in the column, as well as the length of the cable and the gas vent tube.

The active electrode is manufactured in accordance with the following regulatory documents:

• OTT 29.100.99-KTN161-12 RD-91.020.00KTN-170-17
• GOST R 51164

Climatic conditions are a determining factor in the production of active electrodes. The choice of climatic version ensures effective operation in various environmental conditions. The classification and manufacturing of electrodes directly depend on climatic characteristics. Climatic version “O” (general climate, −20°C…+60°C) and version “V” (universal, −4°C…+60°C) are the main options ensuring operability and durability of electrodes under different temperature conditions (GOST 15150).

The ferrosilicon working element is available in two shapes: round and clover-shaped cross-section. The cable from each working element is made of KGN-XL EHZ-U cable, crimped with a cable terminal, and brought to the surface. The casing used for the anode grounder prevents the activator from spilling during storage, evenly distributes the fill along the working element, ensures reliability during transportation and installation, and promotes the distribution of anode current from the working element surface. When used directly in soil, the casing material dissolves quickly. The mechanical strength of the bandage and fastening components (tensile strength) during assembly of complete deep anode grounders into a column is at least 35 kN. The calculated number of anode grounders (AG) per column (at maximum allowable working element weight) is at least 22 units; if necessary, the bandage design can be reinforced to increase the number of AGs in the column (upon request).

Application Area

The GAZ.KMG.F type ferrosilicon deep anode grounders available from us provide effective cathodic protection against corrosion, based on anodic and cathodic reactions, for main pipelines, port and dock hydraulic structures, as well as oilfield and linear gas distribution stations.

They consist of a ferrosilicon metal rod inserted into the ground at a specified depth near the protected object. The grounder is connected to a cathodic station, forming an electrical circuit through soil or water. The ferrosilicon anode becomes passive, maintaining the required potential at a relatively low level and significantly reducing the corrosion rate.

The casing used for GAZ.KMG.F ferrosilicon deep anode grounders prevents the activator from spilling during storage and ensures even distribution of the fill along the working element.

It does not obstruct the distribution of anode current from the working electrode surface and dissolves quickly in soil. For convenience, the GAZ.KMG.F anode grounders are equipped with a cotton transport handle.

To remove gases generated during operation of the working electrodes, a special gas outlet tube is used. It is chemically resistant to anode solutions and operational conditions such as groundwater, brines, or weak acid and alkali solutions.

The permissible number of anode grounders in a column, as well as the length of cables and gas outlet tubes, is determined according to the customer’s technical specification (questionnaire).

GAZ.KMG products are manufactured in accordance with regulatory documentation:

• OTT 29.100.99-KTN161-12;
• RD-91.020.00KTN-170-17;
• GOST R 51164.

They are produced in climate version “O” (general climate version), corresponding to placement category 5 according to GOST 15150. The nominal operating temperature is from -20°C to +60°C. GAZ and PAZ are suitable for operation in seawater, produced in general climate version “B,” and correspond to placement category 5 per GOST 15150. The operating temperature range for these units is -4°C to +60°C.

They are manufactured in climate version O (general climate), placement category 5 per GOST 15150, with a temperature range from -20°C to +60°C.

Ordering GAZ.KMG.F type magnetite deep anode grounders from our website provides a ready-to-use set without additional modifications. It is suitable for insertion into soils with high electrical conductivity. When installed in a borehole, the element should take a vertical position.

Technical Description

The design of magnetite deep anode grounders GAZ.KMG.F includes a special casing that serves as a container for the magnetite electrode surrounded by a coxo-mineral activator. The casing ensures safe transportation and installation. During operation, the container dissolves.

The casing is securely fixed with guide brackets. This is necessary to connect complete deep grounders into a chain to increase current capacity and reduce transition resistance. No more than 24 blocks can be included in a chain.

The venting of gases generated during operation of GAZ.KMG.F magnetite deep anode grounders is managed using a gas outlet tube. Together with the cable system, it is brought to the surface. The gas outlet tube is perforated along its length and manufactured to order, with one tube per working element installed in a single borehole.

The customer determines the number and components of the deep grounding system, specifying how many blocks will be installed and the length of connection cables and drainage tubes. The equipment is selected according to the prepared cathodic protection project.

The complete grounders reach operational mode and low current dispersion resistance in minimal time. The equipment does not require additional modifications, significantly simplifying installation of the anode grounders.

Each block is equipped with a connection cable. The cable length depends on borehole depth and installation height of the element. The cable has no joints and is brought to the surface for connection to the anode line cable. Pricing and delivery terms can be obtained by contacting our manager.

The cable from each working element is made of KGN-XL EHZ-U cable, crimped with a cable terminal, and brought to the surface. The casing used for the anode grounder prevents the activator from spilling during storage, evenly distributes the fill along the working element, ensures reliability during transportation and installation, and promotes the distribution of anode current from the working element surface.
