The Anti-corrosion Technology Measures for Petroleum Machinery

Number of visits: Date:Sep 9,2015

1. The use of highly effective anti-corrosion coatings

In order to prevent the corrosion of petroleum machinery, high efficient anti-corrosion coatings should be used. For example, the anti-corrosion coatings with the nature of environmental protection,acid resistance as well as the anti-corrosion coatings with inorganic polymer properties etc., these anti-corrosion coatings are able to play a role in the anti-corrosion of acidic substances in oil, which play an important part in the control and prevention of the corrosion situation of the petroleum machinery. The first is environmental and anti-corrosion coating, the main anti-corrosion principle of which is to reduce the organic acid, hydrochloric acid, hydrogen sulfide and other acidic organic compounds or acid compounds that can cause the corrosion of petroleum machinery . Next is the inorganic polymer coating, the anti-corrosion principle of which is to prevent and control the the dispersed metals and metal oxides in oil, hence the anti-corrosive purpose could be achieved.

2. The novel anti-corrosion materials for petroleum machinery manufacture

In the manufacture of petroleum machinery, some new materials with stronger, higher and more complete anti-corrosion properties can be used to solve the corrosion problems from the source . For the petroleum machinery manufacturing materials, the materials with strong oxidizing, reducing resistance and strong resistance to acid should be selected scientifically and reasonably, thereby providing higher safety for petroleum machinery and equipment manufacturing, higher quality and more reliable material, so as to improve the anti-corrosion performance of the petroleum machinery equipment, to solve the corrosion problem of petroleum machinery, ultimately ensure the smooth completion of the oil production.

3. Electrochemical anti-corrosion

The so-called electrochemical anti-corrosion is to use the electric current to reduce the corrosion speed of the machine. The anti-corrosion principle of this method is the movement of electrons in the process of corrosion. Before the cathodic protection of the current cathodic protection, the corrosion resistance of the material is achieved by the method of sacrificing the packing of the cathode. If there are enough electrons in the metal surface of the machine, then the corrosion phenomena will become slow or stop. Now the electrochemical corrosion prevention method in the case of different objects
