Magnesium trade mark protectors of PTM type

Magnesium protectors of PTM type, complete with activator and without activator, consist of a working element representing a galvanic anode (protector) made of magnesium alloy with a steel contact core (armature) and a connecting cable led outside.
Protectors are designed for galvanic electrochemical protection against underground corrosion of the outer surface of steel main pipelines transporting natural gas, oil and petroleum products and branches from them, pipelines of compressor, gas distribution, pumping and pumping stations, as well as oil depots, head structures of oil and gas fields (including tanks and well casings), underground gas storage facilities, gas and oil treatment plants, pipelines of thermal power plants, connected to the main pipelines of gas and oil pipelines.
