| 100kW/32 HIGH-FREQUENCY WELDED PIPE MILL LINE |
| |
| 1 General Introduction |
| 100kW/32 high-frcquency welded pipe production line is designed to produce welded pipes of 12 ~ 32mm in diameter and 0.5 ~ 2.0mm in wall thickness as well as square and rectangular pipes and formed sections of the corresponding size. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the production line is designed with new ideas. The application of Mature high frequency induction heating technology and digital speed regulating unit guarantee that the production line works reliably and operates and main tams easily. Being the best inside the stare, the production line can also rival the advanced ones in the world. |
