Forming and Sizing Machine 

1.The forming and sizing mill is the core equipment in the line. It feeds strips of a certain specification into tube blank and welds them into pipes with HF current. When the gradually rolling strip leading by the guiding device reaches the HF welder, the FF forming mode and induction welding adopted in this mill line works. The two sides of the strip are heated to the welding point and are squeezed together. The next procedures are de-burring, cooling, sizing and roughly straightening. Then comes the pipes needed.
