The pulsewise method for controlling corrosion and mechanical destruction of equipment

Abstract. Since the advent of the first technological objects, the problem one number in Chemical and Petrochemical industry is corrosion and premature corrosion-mechanical destruction of the equipment. Despite scales of damages, mass replacement of constructions in production takes to the minimum, and therefore, prevail reconstruction works. Installation of the systems of the corrosion monitoring and control in the most vulnerable parts of technological objects remains the major method of prevention to the premature output of equipment from the working state. This can be done by means of the corrosion monitoring which could use for any materials and environments to identify of character and corrosion rate. Therefore, it is important to select the most effective combination of methods of corrosion control. There are four electrochemical methods of corrosive control: linear polarizationresistance; the alternating current impedance; measurement of electrical noise; measurement of electrode potential. The new electrochemical impulsive method for monitoring of corrosion-mechanical damage of metal is developed. It estimates the damage degree by the general amount of the registered impulses and dynamics of their appearance during corrosion-mechanical destruction.The offered method allows us to control of corrosion-mechanical damage of technological equipment by the change of two parameters: difference potential of equipment in time and dynamics of appearing of impulses of destruction.
