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.

Surface magnetite anode grounders consist of a magnetite electrode manufactured in a tubular shape. A cable of standard length 200 cm is provided for connection. PAZ-MK can be ordered with a longer cable. The cable is equipped with an anti-corrosion protective coating. The cable attachment to the electrode is made with a spring. The entire contact assembly is insulated with a compound based on polymer resins.

The contact assembly is hermetically sealed with a heat-shrinkable sleeve. The number of grounders used is determined by the project. The surface magnetite anode grounder can be positioned vertically or horizontally. The price of surface anode grounders depends on the quantity ordered, cable length, and other options. The standard set includes at least 20 grounders.

Technical Specifications

Delivery of PAZ-MK and additional components is negotiated individually. The standard set includes the necessary consumables, 2 meters of cable, and 20 grounders.

Application Area

The anodes are used in Cathodic Protection (CP) systems for underground structures — main oil and gas pipelines, gas distribution networks, pipelines for transferring hazardous substances, and other similar transport systems.

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. 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 33 units; if necessary, the bandage design can be reinforced to increase the number of AGs in the column (upon request).
