Institute for petroleum, chemical, machinery, engineering, electronics, instruments, ships, pipelines, coal, power plants and other related materials corrosion and related inspection, evaluation, design, research and development of application technology, services, and transfer as the main business scope, such as in anticorrosion materials research and development, production, sales and engineering construction as the main business, such as continuous state, serve the society.

. It can be seen that the protection of metals is of great significance. It is closely related to industrial and agricultural production, scientific experiments and daily life. According to this calculation, the erosion loss of China last year about more than 500 billion yuan, far far from the natural disaster and all kinds of accident losses combined. The United States, The United Kingdom, the former Soviet Union, the former West Germany and other countries from 1969 to 1970 showed that the direct loss caused by erosion accounted for 2.0% to 4.2% of the total national economic income. More and more people are aware that erosion is a severe erosion phenomenon, it is everywhere, all the time, the loss is huge. Research projects of the institute: anode protection, cathodic protection, crude oil electric dehydration instrument, potentiostat, sacrificial anode, cathodic protection construction, electrochemical corrosion protection

With the development of industrialization, the annual loss caused by erosion accounts for about 3-5% of each country's GDP. Now this is familiar with the erroneous area is gradually reversed. Moreover, erosion has the characteristics of universality, concealment, gradual progress and sudden onset, which is not only epidemic, but also a chronic disease, so that most people turn a blind eye to erosion, so that it is common, so that they do not face up to it. From 1964 to 1973, Japan Metal industry Corporation dealt with 1009 equipment damage accidents, 985 of which were related to erosion, accounting for 97.62%.

For a long time, people thought that erosion was a certain phenomenon, a natural law, without hindering the overall situation; Erosion is everywhere, but its harm is not everywhere, nor as terrible as earthquake, fire and other sudden accidents. Auto accidents cost the United States $30 billion a year, fires $11 billion, floods $430 million, winds $1.7 billion, earthquakes $400 million, and erosion costs $70 billion, far more than the rest of these combined.
