Introduction of full automatic expanded metal spiral tube making machine

Compared with traditional duct processing methods (such as manual welding and rectangular duct bending), full automatic expanded metal spiral tube making machine have significant advantages, mainly in terms of production efficiency, sealing, strength, cost control, etc. The following is an analysis of its main advantages:

1. High production efficiency, suitable for mass production
Continuous automated molding：
Metal sheets (galvanized sheets, stainless steel, etc.) are automatically unloaded, leveled, spirally rolled, and occluded without manual intervention.

2. Excellent sealing performance and low air leakage rate 
Spiral bite process: 
Adopt S-shaped or L-shaped locking edge, the bite is tight, and the overall sealing of the air duct is better than the traditional flange connection or welding method. 

3. High structural strength and good pressure resistance 
Spiral corrugation enhancement: 
The spiral structure itself has a higher pressure resistance and is less likely to deform than rectangular air ducts. It is especially suitable for long-distance air supply or negative pressure systems (such as dust removal ducts).

4. Easy installation and low construction cost 
Lightweight design: 
The weight of spiral duct is 20%~30% lighter than that of rectangular duct, reducing the difficulty of transportation and installation. 
Socket connection: 
No flange connection is required, directly using socket or clamp connection, the installation speed is more than 50% faster than traditional duct. 
Save lifting bracket: 
The circular pipe is evenly stressed, the support spacing can be larger, and the amount of brackets used is reduced. 
5. High material utilization rate and low comprehensive cost 
Less scrap: 
The spiral rolling process can maximize the use of metal coils, and the scrap rate is lower than the traditional cutting and bending process.
Low maintenance cost: 
Spiral ducts are not easy to accumulate dust, easy to clean, and the long-term maintenance cost is lower than that of rectangular ducts.

Application scenarios

Engine/gas turbine air intake duct Example: Diesel generator air intake system, gas turbine pre-filter duct.

The full automatic expanded metal spiral tube making machine is particularly suitable for dust removal, engine air intake, clean rooms and other scenarios in large air filter production lines.
