Ductwork refers to the network of conduits, typically made from sheet metal, fiberglass, or other materials, designed to transport air, fumes, dust, or other airborne substances from industrial processes to filtration systems or the atmosphere. It is a critical component of exhaust systems, ensuring proper airflow, pressure management, and containment of contaminants to maintain safe working conditions and environmental compliance.

定义
Ductwork refers to the network of conduits, typically made from sheet metal, fiberglass, or other materials, designed to transport air, fumes, dust, or other airborne substances from industrial processes to filtration systems or the atmosphere. It is a critical component of exhaust systems, ensuring proper airflow, pressure management, and containment of contaminants to maintain safe working conditions and environmental compliance.
工作原理
Ductwork operates on principles of fluid dynamics, utilizing pressure differentials to move air or gases. Air is drawn into the system through intakes, transported through sealed ducts via fans or blowers, and expelled through outlets. The design minimizes resistance (through smooth interiors and proper sizing) and prevents leaks to maintain efficiency and safety.
材料
Common materials include galvanized steel (for corrosion resistance)stainless steel (for high-temperature or corrosive environments)aluminum (lightweight)and fiberglass (for insulation). Thickness typically ranges from 0.5 mm to 2 mmdepending on pressure and application.
Diameter
100-2000 mm
Pressure Rating
Up to 2500 Pa
Airflow Capacity
500-50,000 m³/h
Temperature Range
-40°C to 400°C
标准
ISO 6947DIN 24194

常见问题

What are the main types of ductwork used in industrial exhaust systems?

Common types include spiral ducts (for efficient airflow), rectangular ducts (for space constraints), and flexible ducts (for temporary or complex routing). Selection depends on pressure, temperature, and material compatibility.

How often should industrial ductwork be inspected?

Inspect ductwork at least annually for leaks, corrosion, or blockages. High-use or harsh environments may require quarterly checks to ensure safety and efficiency.
