The principles of active anticorrosion protection

The corrosion is problem which concerns the economics over the whole world The losses created by corrosion are immense. According to different sources the losses created directly by corrosion are in the interval 2 4 % of the gross domestic product of the developed countries and losses resulted from corrosion indirectly as the interruptions in the production, penalties for not meeting the contracts are even much higher. For this reason there is an interest to reduce the losses related to corrosion.In gas industry is the problem of corrosion multiplied by the working conditions of metal material - the aggressive surrounding environment of soil. For this it is necessary to use the most effective protection techniques and technologies. Besides the classical anticorrosion methods of metals as painting with the corrosion resistant paint the active anticorrosion protection is used today
