In many factory exhaust gas treatment solutions,
spiral steel pipe for ventilation ducts plays a subtle yet significant role. It's more than just a piece of steel pipe; it serves as a critical pathway for exhaust gas generation and guaranteed discharge.
First, what's unique about the structure of spiral steel pipe?
• Spiral seam technology: Formed through spiral rolling or welding, the pipe's diameter is uniform and its overall strength is high.
• Flexible material selection: Common materials include galvanized steel, stainless steel, and carbon steel, with selection based on exhaust gas composition, temperature, humidity, and corrosive properties.
• Highly smooth inner wall: Reduces gas flow resistance, lowers energy consumption, and facilitates subsequent cleaning and maintenance.
Second, what is the role of spiral steel pipe in exhaust gas treatment?
1. Exhaust gas transportation: Transports exhaust gas, smoke, or dust generated during the production process from its source to purification equipment (such as spray towers, activated carbon adsorption units, RTO/RCO, etc.).
2. Maintaining system negative pressure: This works with the fan to create a stable negative pressure environment and prevent exhaust gas from escaping.
3. Noise reduction and insulation: Some spiral steel pipes are insulated and silenced to reduce equipment operating noise and heat loss.
Third, what are the advantages of spiral steel pipe compared to other pipes?
• Better sealing: The continuous structure of the spiral seam reduces leak points.
• Higher strength: Compared to ordinary straight-seam pipe, it is more resistant to deformation.
• Easy installation: It can be cut and connected as needed to adapt to complex site layouts.
Fourth, what are the application scenarios of spiral steel pipe?
• Treatment of organic or inorganic waste gas from chemical, electroplating, spraying, printing, etc.
• Boiler flue gas and dust collection systems
• High-humidity and highly corrosive gas transportation environments
Fifth, what details are often overlooked when selecting a spiral steel pipe?
• Material matching: For example, stainless steel or fiberglass is preferred for acidic waste gas.
• Steel pipe diameter design: Too small increases resistance, while too large increases cost.
• Inspection ports: facilitate clearing blockages and inspecting corrosion.
In summary, Spiral steel pipes act like the "blood vessels" of the exhaust gas treatment system, determining whether exhaust gas can be efficiently and safely transported to the treatment equipment. Selecting the right material and optimally designing the pipe diameter are key to ensuring compliance with environmental standards and long-term, stable system operation.
