HRDAULIC MANDREL

Mandrel is a very important part in cold bending processing of long distance pipeline construction. It is matched with outer die in the working procedure to reduce the ovality of bending pipe while the mandrel lied on the inner of pipe. That can avoid breaking pipes. Our staffs have nearly 10 years' experiences; they optimally deign the new mandrel by testing the CRC, GR,DMI,VIETZ, etc cold bending machine mandrel on the construction spots. The characters are as following:

1. International famous components, ensures working reliability.

2. Big diameter cylinder assures the strength of tension.

3. Optimal design polyurethane support block, reduce ovality of cold bending pipe to avoid the wrinkle.

4. Structure is made of high elasticity alloy steel to ensure the resilience of equipment structure after bending.

5. Spring steel plate uses cold working to improve the service life  and avoid crack of it.

6. Mode design, easily remove and repair.

7. Working type: hydraulic
