Unit 20-114 with heat reduction mill

This unit intended for production of water-and gas tubes and structural tubes manufactured from carbon steels.

Unit 20-114 combines together the tube electric welding mill and the heat reduction mill without intermediate tube's cutting. The continuity and full automation of the process provide high quality and output at minimal metal consumption. The production of electric-welded tubes after the tube electric welding mill is provided.
