The development and application of corrosion monitoring technology is mainly due to the increasing emphasis on material corrosion and the seriousness of its consequences. Material is the material basis for the survival and development of mankind and the main carrier of material civilization. It is closely related to the national economic construction, national defense construction and people's life. Material is so important, so material damage caused by the disaster and loss are often incalculable. The phenomenon of chemical or electrochemical reaction between the material and the environment (including humidity, temperature, pressure, air pollution, etc.) leading to the decay of performance is called corrosion. Corrosion is a quiet destruction, but the consequences are very serious , Not only cause a lot of material loss, waste, hinder the development of high technology, but also pollute the environment, and even endanger people's lives and property safety.
The serious consequences of a series of corrosion accidents have aroused the concern of all sectors of society and the public at large. People are gradually realizing that it is necessary to know more about corrosion and understand corrosion. If we can take effective corrosion monitoring in advance, all these corrosion accidents in history are Possible to avoid. To carry out corrosion monitoring, for various industries, especially aerospace, petrochemical and other industries, are an important guarantee for the safe operation of enterprises. The significance of carrying out corrosion monitoring is very significant. Here are some major aspects:
Prevent accidents. Corrosion monitoring can be used to monitor the corrosion of the media at any time, and corrosion conditions in excess of the pre-set conditions, the timely investigation of the problem to prevent major accidents. For example, the oil and gas industry can adopt on-line ultrasonic thickness measurement and other methods to monitor pipeline corrosion so as to avoid pipeline leakage caused by corrosion.
Forecast equipment life. By corrosion monitoring can accurately predict the service life of equipment, both to avoid frequent replacement of equipment lead to increased costs, to ensure the safe operation of equipment. Provide the basis for scientific management. Take the petroleum industry as an example. In order to slow down the internal corrosion of process equipment during petroleum refining and processing, managers usually use certain types and dosage of corrosion inhibitors according to their own experience. After the corrosion monitoring technology is adopted, the type or proportion of corrosion inhibitor can be adjusted according to the monitoring result, so as to greatly enhance the effect of using the corrosion inhibitor.
