1. Preparation of finned tubes before production

     1. According to the external dimensions, structural parameters and material parameters of the finned tube, determine the processing technology of the finned tube;

     2. According to the material characteristics of the finned tube, determine the suitable processing tool;

     3. Determine the appropriate processing mold according to the shape and size of the finned tube;

     4. Determine the appropriate welding process according to the structural parameters of the finned tube;

     5. Determine the appropriate processing equipment according to the shape and size of the finned tube;

2. Finned tube production process

     1. Cutting: According to the shape and size of the finned tube, use a cutting machine to cut the material to ensure the shape of the finned tube;

     2. Bending: According to the structural parameters of the finned tube, the bending machine is used to bend the material to ensure the structural parameters of the finned tube;

     3. Welding: Use appropriate welding process to weld each part of the finned tube according to the structural parameters of the finned tube;

     4. Polishing: use a polishing machine to polish the finned tubes to ensure the surface finish of the finned tubes;

     5. Inspection: Check the external dimensions, structural parameters and surface quality of the finned tubes to ensure that the finned tubes meet the quality requirements.
