Regeneration of worn-out rolling mandrels for seamless tubes

The chrome-plated mandrels are used to create the initial hole in the billet that will later become a seamless tube. During the process, these tools undergo significant friction and harsh process conditions. Therefore, constant maintenance of the involved equipment is required.

Officine Meccaniche Barni has an internal department dedicated to the regeneration of worn-out mandrels.

Specifically, the machine shop consists of:

- mandrel screwing/unscrewing machine;
- automatic press for mandrel straightening;
- mandrel rolling and repair systems.

Officine Meccaniche Barni is also capable of providing complementary machines to the regeneration aisle, offering the convenience of relying on a single supplier. The range of complementary machines includes the regenerator lathe, the chrome-plating machine, and the mandrel heating furnace. Barni's machine range covers dimensions from 7 to 18 inches.
