5 transmission line
 Part 1:
At the starting end of the production line, to the feeding machine, the steel pipe is conveyed to the feeding machine, and a single steel pipe is connected in series so as to ensure continuous production.
Divided into three sections, each section of the 6m, which has a 2.2KW variable frequency motor
 Part 2:
Is located at the end of the production line, the end of the production line, the finished tube output, and will be connected to a series of steel pipe separation, separation of finished tube off the assembly line
Divided into 3 sections, each section of the 6m, of which 2 sections of the 2.2KW variable frequency speed control motor
