Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, in particular to an intelligent expanding machine for corrosion-resistant and high-performance stainless steel pipes. Background Art

[0002] A diameter expander, also known as a belling machine, is a mechanical device used to expand the ends of steel materials.
