Present Application Status，Demand Analysis and Thinking Concerning Steel Pipe Used in New Energy Field

Thanks to the Strategy of Double Carbon （carbon dioxide emission peak and neutrality） the development of new energy and related fields has brought the new application prospect of steel pipes，and put forward new requirements for their functions and performances. Focusing on the CO₂ transmission pipe as used in the technology fields of carbon ca- pture，utilization and storage for safety，the hydrogen gas transmission pipe as used in the hydrogen energy field，and the injection production pipe as used for salt cavern compressed air energy storage in the energy storage field，here in the article，the present application status and the research progress of the new energy service steel pipes is summarized，and the demands for the pipes in various fields are analyzed. Furthermore，presented here，under the Double Carbon Strategy background，are relevant thoughts and suggestions about the essential theoretical research，the critical technology development，and the standard system construction of the new energy service steel pipes.
