PM-20 is a special magnesium alloy that can be packaged in a cotton bag with an activator composition. Two modifications of the model are available for sale. One is supplied in a bag, the other without it. Each is equipped with a terminal for cable connection. PM-20 can be ordered with any cable length.

Installation of PM is performed in a trench or borehole. The anode is then covered with soil and compacted. Models with a bag and activator must be additionally moistened with water. Some types of PM can be installed under tank bottoms. The activator contains:

• Bentonite clay – 50% of the composition;
• Construction gypsum – 25% of the composition;
• Epsomite – 25% of the composition.

The magnesium anode is suitable for use in soil with a specific resistance of no more than 50 Ohm/m. The service life depends on the type of soil, size, and weight of the PM. On average, it is about 5–10 years of continuous use. The price of PM-20 depends on the product modification and additional components.

Product Specifications

The potential of the magnesium anodes is 1600 mV, and the current output reaches 2200 A·h.

Magnesium anodes consist of a magnesium alloy placed in a cotton bag, supplemented with a special activator. The anode has a terminal for cable connection, with the cable length specified when ordering. The customer can select the required cable length and order PM-15 in one of the available modifications.

PM installation is performed in a borehole or trench. To ensure good contact, the surrounding space is compacted. The activator is activated by adding water during installation. Magnesium anodes are used when laying pipelines in locations that are difficult to access for maintenance, such as under water, in swampy areas, or beneath railways.

The final order price depends on the selected product model, additional cable parameters, and other customer requirements. The service life of the anode depends on the aggressiveness of the soil in which it is placed, averaging around 15 years. The protection level of the bottoms of various tanks buried in soil reaches 95%.

Product Specifications

PM-10 is made of a magnesium alloy with a steel core inside. The anode is packaged in a cotton bag. The connecting cable is led outside. The product package includes a standard-length cable. PM-10 with a longer cable can be ordered at the customer’s discretion.

Stable operation of PM is ensured by an activator located in the cotton bag together with the magnesium alloy. This prevents the formation of insoluble films on the anode during use. The customer can choose one of two product modifications – PM-10 and PM-10(U). The abbreviation U indicates that the anode is supplied in a bag.

Installation of the anodes is performed into the soil. Along the pipeline, they are installed at a rate of 1 unit per 1–2 km. This is an average rate, depending on pipe diameter and route length. Group installation of 5–15 anodes at a time is also possible. The price of PM-10 depends on the selected modification and cable length.

Product Specifications

PM-10 is designed for use in soils with resistance not less than 50 Ohm/m. The device provides effective current output of 2200 A·h. The electrode with a potential of 1600 mV is placed in a special activator, which prevents the formation of poorly soluble films during use. The activator contains bentonite clay, construction gypsum, and epsomite.

PM-type protectors consist of a magnesium alloy packaged in cotton bags. Inside the magnesium casting is a steel core. Its lead is connected to a cable. Magnesium protectors PM-5 can be ordered in several modifications. The metal protection functions are provided by generating a protective potential.

PM-5 is installed directly into a borehole that must be drilled in advance. The bag with the magnesium casting is lowered to the required depth, covered with soil, and compacted around it. To activate the reaction, water must be added to the trench or borehole. The lead wire is connected via terminals to the control measurement point. A separate terminal is provided for connecting the drainage cable.

The price of PM-5 depends on the selected product modification. Each protector has several advantages. The main ones include the ability to use in soils with resistance up to 50 Ohm·m. The cotton bag contains a powder activator, which allows achieving a high potential.
