Structurally, the polymer anode grounding device consists of an electrode made of polymers resistant to oil, petroleum products, anode dissolution products, and gases, with a low specific electrical resistance not exceeding 1.0 Ω·m, containing a tinned flexible copper conductor placed along the central axis. The ends of the electrode are connected to a KGN-KHL EHZ-U cable through a contact assembly that includes a sealing element and polyolefin heat-shrink sleeves resistant to ultraviolet radiation and aggressive environmental conditions.

Improved operational reliability of the polymer anode grounding device within cathodic protection systems for buried metal structures is achieved through the use of electrodes with low specific electrical resistance, providing exponential distribution of protective current across the entire surface of the active element.

Repairability of the polymer anode grounding device is ensured by the use of an installation casing filled with conductive gel.

Two installation configurations of the repairable anode grounding device are available: horizontal and vertical.

In addition to enhanced performance characteristics, the service life is extended to not less than 50 years.

The project for establishing the production of repairable anode grounding devices using conductive polymers with reduced resistance was implemented with the support of the Foundation for Assistance to Small Innovative Enterprises in the Scientific and Technical Sphere (Innovation Support Fund), grant agreement No. 759ГКС4/70981 dated 17.11.2021.

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).

It performs two critical functions: ensuring high reliability during transportation and installation, and promoting efficient distribution of the anode current. The mounting handle is an integral part of the grounding device, providing convenience during work in soil and facilitating handling operations. The casing of this device degrades during direct operation in soil.

Applications

The active element made of titanium with MMO coating is placed inside a titanium protective casing (PAZ.KMG.T) with a diameter of 16 cm and a length of up to 220 cm. The standard configuration of PAZ.KMG.T includes a cable lead with a length of 2 m.

To prevent backfill loss during storage, the backfill is evenly distributed along and across the active element to ensure reliability during transportation and installation, as well as unrestricted current distribution from the active surface.

The casing dissolves rapidly when placed in any type of soil, which facilitates installation and handling operations due to the presence of a special mounting handle made of cotton material. The length is determined according to specific customer requirements specified in the technical documentation.

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.
