What Factors Should Be Paid Attention To in The Machining Of Spiral Duct?

The spiral duct machine is a machine that produces spiral ducts. Spiral duct machines, also known as spiral slit thin-walled ducts, were early used in Western military industry, such as warships, platoon (transmission) air systems, etc., and later in civilian facilities such as trains, subways, and mines. The system can handle stainless steel, galvanized steel, aluminum and copper plates, automatic coiling equipment, automatic installation of measuring equipment, and an automatic digital system that can produce different pipes. Many people are not familiar with spiral duct machines.

At present, the spiral duct market is generally divided into three categories according to material: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. Among them, the stainless steel air duct is of good quality and strong applicability, but the price is high. The spiral ducts currently circulating in the market use galvanized sheets. Galvanized spiral duct is basically the characteristic of stainless steel spiral duct.

The spiral tube is made of striped coil material, which is bitten by the tube forming machine, and rolled into a round tube along the involute track. At the same time, the length is cut according to the demand, and it is launched on the market. With excellent performance and low cost, it is used in shipbuilding, ventilation, air conditioning, air transportation, tunnels and other construction industries. Spiral duct can withstand pressure, the wall thickness of the pipe is 4 times that of the pipe body, the pipe has a great rigidity, can withstand pressure load and non-destructive deformation, and the thickness of the wood can be reduced by 15%. This reduces production costs. Therefore, the pipeline vibration caused by low-frequency noise is small, the airflow performance is good, the system pressure drop is small, and the daily operation power consumption of the system is low.
