Brief Introduction:
This steel pipe expander machine can straighten the roundness of pipe.
The working principle of expanding machine is to have the pipe, after forming and qualified internal and external welding, set outside the expansion head of the Expander, and to expand the internal wall of the pipe section by section through the expansion of the moulds, causing the material flow along the pipe wall, thus eliminating strange internal stress developed during forming and welding.
The moulds:
Precision:
| Tubular Product Diameter(mm) | ¢80-¢200 | ¢200-¢400 |
| Roundness Error(mm) | ±0.05 | ±0.25 |
Parameters:
| Tubular Product Diameter(mm) | Tubular Product Thickness(mm) | Tubular Product Length(mm) |
| ¢80-¢400 | 1-2 | 100-1000 |
Last but not the least, the moulds or the machine can be designed according to your requirements. It is customizable :)
