'''Folded Spiral-seam Tubing''' can process a round duct with maximum diameter 1.4m. Both of its intensity and airproofing are good. All diameter rounds change drastically. With constant high-speed cutting equipment, the strip speed is fast, the capability is stable. | '''Folded Spiral-seam Tubing''' can process a round duct with maximum diameter 1.4m.

Folded Spiral-seam Tubing is a round duct manufacturing machine. It processes a maximum diameter round duct up to 1.4m. with a strong seal. It is easy to change the diameter for different duct sizes. It works quickly and with a constant high-speed cutting unit. The size of the diameter for round duct can be quickly changed. | |||
The processing capablity of bow round duct machine is strong, and the construction is simple, fast. It's easy to operate and requires little attention on circumstance and electric appliances. | |||
