The petrochemical industry has extremely high requirements for the operation of compressors, which is the key to determining the safety of the production process and the quality of the products. AST centrifugal compressors rely on their own advantages to adapt to various complex working conditions, ensure that the equipment always operates stably, have low maintenance costs, maintain high efficiency under high pressure ratio and large flow conditions, and reduce energy consumption. They are widely used in gas boosting and transportation, and run through multiple production links such as oil refining, natural gas processing, and ethylene production to ensure efficient, safe, and environmentally friendly operation of the process.
