1. Polysulfide in petroleum leads to high pressure corrosion of petroleum machinery
Most of China's oil contains more polysulfides, in the process of oil mining, petroleum machinery and equipment in contact with oil is easy to be corroded by polysulfides in oil, and then produce a variety of polysulfides on the surface of petroleum machinery high pressure, in the operation of petroleum machinery high pressure, these polysulfides will bring a lot of instability factors to petroleum machinery. In addition, the mechanical equipment is exposed to the air for a long time, and the carbon dioxide and moisture in the air will react with the corrosion part of the mechanical equipment, and eventually lead to the corrosion degree of the entire petroleum machinery and equipment is more serious.
2. The sulfide in the oil leads to the high pressure rot of the petroleum machinery
This corrosion phenomenon is mainly caused by impurities in petroleum products, the main component of these impurities is sulfide. Sulfides can chemically react with water in petroleum, resulting in the production of a large amount of hydrogen sulfide in petroleum, which is reductive and acidic, resulting in serious corrosion of petroleum machinery and equipment. In addition, there are a large number of chemical impurities in oil, which also cause the corrosion of petroleum machinery and equipment to a large extent.
3. The chloride in oil leads to high pressure corrosion of petroleum machinery
According to the survey, a lot of oil now contains a lot of salt water, if the chemical hydrolysis of salt water, it will be converted into hydrochloric acid, for petroleum machinery, hydrochloric acid is one of the key factors leading to corrosion of petroleum machinery and equipment, resulting in serious corrosion of petroleum machinery and equipment, thereby reducing the quality and safety of petroleum machinery and equipment.
