Vertical Straightener
|
|
|
| Vertical Straightener is a machine that rollers are horizontal crossly disposed and with double travel driving. The die of rollers is elliptical curve, to ensure no defects on the surface of pipe like helical mark and defects and improve section elliplicity. It is used to straighten camber of all kinds of pipes. |
