Yes. One High Frequency Welded Tube Mill can produce round square and rectangular tubes within its designed production range. By changing the appropriate forming and sizing tooling, manufacturers can produce different tube shapes on the same production line, providing greater flexibility for different market requirements.

For example, HF 28 model High Frequency Welded Tube Mill can be configured to produce round tubes from 12.7 to 50.8 mm, square tubes from 10 × 10 to 40 × 40 mm, and rectangular tubes from 10 × 10 to 20 × 60 mm. The actual production range depends on the machine configuration, tooling design, material and required wall thickness.

One important feature of a tube mill is the round to square and rectangular forming process. During production, the steel strip is first formed and welded into a round tube. The round welded tube then passes through the downstream sizing section, where additional forming rolls gradually change the tube into a square or rectangular profile.

Therefore, when changing from a round tube to a square or rectangular tube, it is not always necessary to replace the complete set of tooling. For tube sizes that are within the corresponding production range, the downstream sizing and forming tooling can be changed or adjusted according to the required profile.

This design can significantly reduce tooling changeover time and improve production flexibility. Manufacturers can use one High Frequency Welded Tube Mill to serve different applications such as furniture tubes, construction tubes, scaffolding, fencing and structural profiles.

However, the compatible square and rectangular sizes depend on the machine's round tube range and tooling design. When selecting a tube mill, customers should provide their required round square and rectangular tube sizes so that the forming and sizing sections can be properly configured.

In summary, one High Frequency Welded Tube Mill can produce round square and rectangular tubes within its designed range. With a suitable round to square forming system and properly designed tooling, manufacturers can switch between different tube profiles without replacing the complete tooling set.
