A Spiral Duct Machine is a specialized piece of equipment used to manufacture spiral air ducts. These ducts are commonly used in various industries, including military, and for ventilation and exhaust systems in trains and subways.
The primary function of the Spiral Duct Machine is to facilitate air circulation between two places, serving as a means of ventilation¹. The machine produces high-quality Spiral Ducts that operate quietly without significant noise, water leakage, or air leakage. Additionally, these ducts exhibit excellent resistance to corrosion.
The Spiral Duct Machine was initially developed and produced in Switzerland. However, with the introduction of advanced technology, many countries, including China, have begun to develop their own Spiral Duct Machines.
The Spiral Duct Machine is a high-end round tube processing equipment. Compared to other round tube manufacturing equipment, this machine boasts versatility and flexibility, capable of processing circular tubes with diameters ranging from Φ80mm to 1500mm.
The Spiral Duct is typically coated with a layer of zinc on the iron duct to protect it. The innovative spiral pressing rib technology provides the Spiral Duct with excellent strength to withstand pressure.
Spiral Ducts were first introduced in military industries in Western countries before being adopted in civilian facilities like trains, subways, and mines.
Please note that the use of Spiral Ducts in office buildings, shopping malls, and subways in the United States stands at 95.6%, while the use of Spiral Ducts for central air-conditioning in residential buildings is at 72.5%.
A Spiral Duct Machine operates under the control of a Programmable Logic Controller (PLC) program and is managed through a touchscreen interface. The main machine can be frequency-modulated and features a stepless speed control.
Here's a simplified overview of the Spiral Duct fabrication process:
A customer receives the slit coil, which is placed on an uncoiler.
The coil is sent through a rough leveler to flatten the material.
It is then sent through an edge trimmer and formed.
The forming process sends the strip through an inner and outer welding stage that moves it in a circular motion to form a spiral.
The spiral duct machine produces ducts by spiraling and locking strips of metal together to form a continuous piece. After the addition of the spiral rib, the thickness of the lock seam is four times that of the tube, resulting in a highly rigid pipe that can withstand maximum pressure without any damage. Additionally, the material thickness can be reduced by 15%, leading to a reduction in cost.
