1. It should be ensured that the bending direction of the steel strip rolled into the steel pipe is consistent with the natural bending direction of the steel coil. That is, the upper disassembly type is suitable for the lower coil forming method, and the lower disassembly type is suitable for the upper coil forming method, so that the influence of steel strip deformation on the mechanical properties of the steel pipe can be minimized, and the steel strip deformation bending moment during the forming process can also be reduced, thereby reducing the equipment load;

2. The unwinding machine must apply a certain amount of tension to the advancing steel belt to prevent loosening of the coil;
3. In the front pendulum unit, the unwinding machine plays a key role in centering and correcting the deviation of the steel belt delivery. Therefore, the unwinding machine must have the process performance of ensuring the horizontal steel coil position stably and accurately and correcting the deviation of the steel belt at any time.
