The petrochemical industry is my country’s pillar industry. It mainly processes and sells crude oil and natural gas. In the process of petrochemical production, a variety of highly corrosive acids and alkalis are used and produced, such as sulfuric acid, hydrochloric acid, caustic soda, etc. The possibility of equipment and pipeline corrosion problems is high, and it needs to undergo many physical and chemical reactions and mass transfer, Heat transfer unit operation, some process control conditions are extremely harsh, such as high temperature, high pressure, low temperature, vacuum, etc. These harsh conditions impose strict requirements on the manufacture and maintenance of petrochemical production equipment. Therefore, special materials are required for key components of certain equipment and in special environments. Stellite alloys play their role in corrosion resistance, wear resistance and high temperature resistance. , provides solutions for many production links and component processing.
