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).

In the standard configuration, the cable lead length is 2 m. The protective casing prevents backfill loss during storage. It shields the backfill from adverse impacts and helps ensure uniform distribution along the active element.

Once the PAZ.KMG.M magnetite anode grounding device, which can be ordered from us, is ready for operation and placed in soil, the protective casing dissolves rapidly, allowing the backfill to disperse and begin interacting with the surrounding medium to provide effective corrosion protection.

The mounting handle enables quick and safe placement at the required location, as well as easy repositioning when necessary. It ensures secure and reliable handling during transportation and installation.

Application

The purpose of anodes is to prevent corrosion (cathodic protection). They are used in cathodic protection systems on main gas and oil pipelines, gas distribution networks, and other pipeline systems transporting hazardous media. PAZ.KMG.M magnetite surface anode grounding devices may be installed vertically or horizontally.

Technical description

A magnetite grounding device is a specialized unit containing a magnetite electrode inside a thin galvanized steel shell. KMA coke-mineral backfill fills the remaining internal space. The housing ensures uniform distribution of the backfill around the electrode and simplifies transportation and installation. The shell dissolves shortly after placement in soil. To facilitate installation, the upper part of the design is equipped with a bracket.

In the standard configuration, the connection cable of PAZ.KMG.M magnetite surface anode grounding devices has a length of 200 cm. The cathodic protection design determines the number of grounding devices to be installed and their spacing.

The anode cable is connected to the pipeline using thermite welding or cable clamps. Cable joints are insulated using heat-shrink sleeves.

• uses a special KGN-XL-EHZ-U connecting cable of own production with reinforced insulation and sheath;
• reduced current spread resistance due to improved formula of in-house produced KMA.KMG coxo-mineral activator;
• dissolution rate reduced to 0.15 kg/A·year by adding chromium and other modifiers during production of the working element to achieve a unique alloy composition;
• uniform dissolution of the anode grounder achieved through an improved geometric design, ensuring exponential current distribution across the entire working element surface.

Products are used in cathodic protection systems for:

• main, field, and other pipelines, and multi-line pipeline systems in any soils, including rocky, arid, desert, and permafrost soils;
• branched communications of compressor stations, gas distribution, oil pumping stations, thermal power plants, and other industrial sites;
• technological tanks of any purpose;
• port and berth structures, offshore platforms, and other hydraulic engineering structures.

The standard cable lead length is 2 meters.

The protective casing used for the AZP-P prevents the activator from spilling during storage, ensures uniform distribution of the backfill along the working element, provides reliability during transportation and installation, and reduces the transition resistance to current spreading of the anode grounding system. When installed directly in the soil, the casing quickly dissolves.

For convenient installation and handling operations, the anode ground electrode is equipped with a transport handle.

The length of the anode cable is determined according to the Customer’s technical specification.
