The pipe diameter range of One High Frequency Welded Tube Mill is limited by its machine design, forming system and tooling configuration. Since different customers have different pipe production requirements, tube mills are available in various models to cover different diameter and wall thickness ranges.

For smaller diameter tubes, the HF20 Model Tube Mill can produce round tubes from 8 to 19 mm with a wall thickness of 0.25 to 0.8 mm. The HF25 Model Tube Mill covers 12.7 to 32 mm with a thickness range of 0.4 to 1.2 mm, while the HF28 Model Tube Mill produces 16 to 50.8 mm round tubes with thicknesses from 0.4 to 1.8 mm.

For medium size applications, the HF32 Model Tube Mill covers 15 to 63.5 mm with a wall thickness of 0.7 to 2.5 mm. The HF50 Model Tube Mill covers 19 to 76 mm and 0.8 to 3.25 mm, while the HF76 Model Tube Mill produces 38.1 to 102 mm round tubes with thicknesses from 1.0 to 3.5 mm.

For larger diameter production, the HF89 Model Tube Mill covers 48 to 114 mm with a wall thickness of 1.2 to 4.0 mm. The HF165 Model Tube Mill covers 89 to 165 mm with thicknesses from 2.0 to 8.0 mm.

In addition to standard models, customized tube mills can be designed according to specific production requirements. For example, the 50K95 Model Tube Mill covers 31.8 to 95 mm with a thickness range of 0.8 to 3.0 mm, while the 76K127 Model Tube Mill covers 50.8 to 127 mm with thicknesses from 1.2 to 3.0 mm.

Choosing the correct tube mill should consider not only the maximum pipe diameter but also the minimum diameter, wall thickness, steel material, production speed and required pipe shapes. Providing the complete product range helps determine the most suitable machine model and tooling configuration.
