In the petrochemical industry, due to the long-term operation of equipment in harsh environments, it is easy to cause corrosion and rust of equipment, which seriously affects the performance of equipment. However, using solvents and emulsions to clean the surface of pipelines can only remove oil, grease, dust and other pollution, but cannot remove the rust layer, oxide scale, fouling and other dirt on the surface of pipelines. Using tools such as wire brushes to polish the surface of pipelines can easily damage the surface of pipelines, and it is labor-intensive, polluting the environment and inefficient. However, using laser cleaning technology can solve the above problems very well.

　　Compared with traditional cleaning methods such as mechanical friction cleaning, chemical corrosion cleaning, liquid-solid strong impact cleaning, and high-frequency ultrasonic cleaning, laser cleaning has the following five obvious advantages:

　　1. Green cleaning: without the use of any chemicals, the cleaned waste is solid and harmless powder, which can completely solve the problem of environmental pollution caused by chemical cleaning.

　　2. Non-destructive cleaning: Laser cleaning is non-abrasive, non-contact, and has no thermal effect. It does not generate mechanical force on the object to be cleaned, does not damage the surface of the object, does not damage the substrate, and does not produce secondary pollution.

　　3. Low-cost cleaning: The laser cleaning system has a high initial investment, but it can be used stably for a long time, with a service life of up to 10 years. It has low operating costs, high speed, high efficiency, and saves time. It can quickly achieve a return on investment. In the long run, the cost is lower than that of traditional cleaning methods.

　　4. Precision and precise cleaning: Laser cleaning can remove various types of contaminants on the surface of various materials, achieving a cleanliness that cannot be achieved by conventional cleaning. And it can also selectively clean the contaminants on the surface of the material without damaging the surface of the material.

　　5. Automated cleaning: Lasers can be transmitted through optical fibers to cooperate with robots to achieve long-distance operation, and can clean complex parts of structures that are not easy to achieve by traditional methods. This feature also makes the safety of operators in some dangerous places more secure. Automated equipment can be used to achieve automated cleaning.

　　Laser cleaning technology meets the cleaning requirements of complex modeling and precise positioning in the field of industrial processing, achieving high cleanliness cleaning effect and low comprehensive cost production efficiency. Mainly used in automobile manufacturing, machining, electronic processing, cultural relics restoration, mold industry, shipbuilding industry, food processing industry, petrochemical and other industries processing, petrochemical and other industries.
