The application discloses a production process and a production device of a high-pressure-resistant, low-temperature-resistant and corrosion-resistant austenitic seamless stainless pipe for aerospace, and the production process comprises the following steps: raw material preparation, cutting, heating treatment, rolling forming, heat treatment, cooling treatment, straightening treatment, surface treatment, quality detection and packaging and warehousing, and the production equipment used in the cooling treatment step comprises a comprehensive billet cooling box, a load driving hydraulic cylinder, a billet air cooling conveyor and a medium cooling conveying claw. The application has four cooling treatments of water quenching, oil quenching, gas quenching and air cooling, the cooling conveying assembly mechanism makes the billet have two conveying routes, can better make the billet synchronously cooled in two cooling modes of liquid medium cooling and gas medium cooling in different modes, prevents the cooling treatment of the latter billet from being affected by the former billet, and improves the free flexibility of the cooling process operation.
