The composition and key points of spiral duct machine

Spiral ducting is made from a strip of coiled material. It is rolled into a round tube using a tweezer along an involute track. It is then cut to length according to demand and released to market. Its excellent performance and low cost make it suitable for applications in shipbuilding, ventilation, air conditioning, air transportation, tunnel construction, and other industries. Spiral ducting can withstand high pressures, with a wall thickness four times the body thickness, resulting in high duct rigidity. It can withstand high pressure loads and deform without damage, while reducing the wood thickness by 15%, thus reducing production costs.

As a result, low-frequency noise-induced duct vibration is minimized, airflow performance is improved, system pressure drop is minimized, and power consumption is reduced during normal operation. Currently, flat oval ducting can also be used to reduce the height of the duct footprint. Flat oval ducting uses specialized equipment to process round tubes into flat ovals by stretching.
