The rise of China's petrochemical industry in the 1960s, now has more than 100 medium-sized petrochemical enterprises, almost all over the country. Annually for the state to provide a large number of petroleum products, synthetic fibers, plastics and fertilizers, as well as some basic chemical raw materials, to improve the rapid development of national economy and people's life has made a great contribution. At the same time, fires and explosions caused by the petrochemical industry due to unsafe cutting also occur frequently, cause serious damage to state property and people's lives and safety.(water jet cutting machine)
According to the China Petrochemical Corporation from 1983 to 1993 statistics, in 1143 the statistics from all kinds of accidents, fire and explosion accidents accounted for 23.64 percent, the loss accounted for 40 percent, and some destroyed dozens or even hundreds equipment, a full set of production equipment to destroy some or all of the plant, resulting in a full plant shutdown, seriously affected the production and economic efficiency, very profound lesson.
Because of the special nature of the working environment and equipment Petrochemical industry needs strict management and control, the device is running media are flammable substances, so job security has become the biggest focus of attention. Especially in equipment maintenance, installation and construction, the construction process of cutting security issues have become the most important issue of concern enterprises. The water cutting / waterjet is a cold cutting technology, water and abrasive cutting, cutting temperature low. In the process does not produce heat (or produce very little heat), this will not produce security risk, ensure the safety of petrochemical enterprises in the construction process of cutting installation and construction.
