The application and development of thermal spray processing technology in the petroleum and petrochemical industry should not be underestimated

       The biggest advantage of using thermal spray processing technology is that it can prepare a surface functional thin layer that is superior to the bulk material in a variety of ways. Wear resistance, corrosion resistance and high temperature resistance. Commonly used thermal spraying processing methods include flame spraying, arc spraying, plasma spraying, explosive spraying, and supersonic flame spraying. Among them, plasma spraying, supersonic flame spraying, and arc spraying have an increasing market share. Thermal spray processing technology is mainly used in the petroleum and petrochemical industry to repair petroleum machinery, improve the wear resistance of mechanical parts and the corrosion resistance of containers, pipes and towers. It is imperative to further popularize thermal spray processing technology in the petroleum and petrochemical industry and take the road of low-cost development.
