Petrochemical industry is the pillar industry of our country. The petrochemical industry has a long production line and involves a wide range of areas. Sinopec alone has nearly 6,000km oil and gas transmission pipelines for crude oil, refined oil and natural gas, and petrochemical enterprises have oilfields, oil production plants, refineries, chemical plants, oil detanks, gas stations and oil (gas) transmission pipelines throughout the country.

China's three major petroleum and petrochemical groups - Sinopec, China National Petroleum corporation and China National Offshore Oil Corporation

The fixed assets have reached more than 600 billion yuan, and the number of employees has reached more than 2 million. The petrochemical industry plays a decisive role in the development of China's national economy. The petrochemical industry is a high-risk industry, with its own industry characteristics: (1) petrochemical production involved in the material risk, fire, explosion, group death and injury accident probability is high; (2) Petrochemical production technology is complex, operation conditions are harsh, prone to sudden catastrophic accidents; (3) large-scale equipment, large production scale, strong continuity, individual accidents affect the overall situation; (4) Device technology intensive, capital intensive, accident property loss. According to the statistics and analysis of the major accidents in the world petrochemical industry from 1969 to 1997, it is found that the direct economic losses of a single set of accidents are staggering, such as the explosion in the Texas plant of Phillips Oil Company in October 1989, the property losses are as high as 812 million DOLLARS. The direct economic loss of occidental Petroleum's North Sea oil platform accident in 1998 amounted to us $300 million. An accident involving a semi-submersible offshore Brazil in 2001 cost more than $500m.

High safety and reliability requirements for petrochemical industry equipment, in the case of meet the quality requirements at the lowest cost to achieve the ultimate goal, one of the important measures is to take scientific monitoring and fault diagnosis method for equipment maintenance, so that they can find early equipment hidden trouble, improve the reliability of equipment, reduce the cost of operation and maintenance. Taking the Acrylic fiber Business Division of Shanghai Petrochemical As an example, through strengthening maintenance and condition detection, adopting point inspection management system and optimizing maintenance cycle, the annual maintenance of stopped (on) vehicles reduced 56 times compared with the same period last year, the daily production capacity increased 2.78% compared with the same period last year, the comprehensive energy consumption decreased 8.1% compared with the same period last year, and the cost decreased 21.074 million yuan.
