219 TUBE MILL LINE
The Tube Mill is a combination of equipment installed in a line for the production of High Frequency Induction Welded (HFIW) carbon steel tubes. The process involved is cold forming of carbon steel strip in circular shape, longitudinal welding, sizing, converting into specified shape and cutting to pre determined length.
Technological Flow：
Steel strip → Coil car → Uncoiling →Coil peeler → Pinch & Leveling →Shearing and butt welding → Accumulator → Forming → Welding → Bead remover →Water cooling →Sizing → Turks head → Flying saw cutting →End facing & Chamfering(Option) → Pipe collecting.
