Spiral Exhaust Pipes — Air Handling Systems

Duct Incorporated offers spiral exhaust pipes from 3 inches up to 80 inches and beyond. Standard diameters include 3 through 16 inches in defined increments, with larger custom sizes available. This wide range accommodates everything from compact fume extraction lines to large-scale industrial ventilation and material handling ductwork.

Pipes are available in galvanized steel, galvaneal, stainless steel 304, stainless steel 316, and aluminum. Galvanized and galvaneal suit general HVAC and ventilation. Stainless 304 and 316 are ideal for corrosive or food-grade environments. Aluminum provides a lightweight option for exhaust and air distribution applications where weight is a concern.

Yes. Duct Incorporated offers both standard and custom fabrication options. Custom sizing and configurations are available for specialized industrial requirements, including non-standard diameters, unique material combinations, and system-specific designs. Design assistance and sizing information services are provided to help engineers and contractors specify the right solution.

Gage standards vary by diameter: 3-inch pipe uses 24 gage, 4- to 13-inch pipe uses 22 gage, and 14- to 16-inch pipe uses 20 gage. These industry-standard specifications ensure structural integrity, appropriate wall thickness for pressure handling, and compatibility with standard ductwork fittings and clamps.

Duct Incorporated's spiral exhaust pipes are compatible with a comprehensive range of components including elbows, adapters, reducers, branches, caps, clamps, hangers, hoses, and hoods. The LaserLock modular clamp-together system also integrates seamlessly, enabling fast field assembly without welding or special tools.

Spiral exhaust pipes serve industrial dust collection, pneumatic material conveying, HVAC and air distribution, fume extraction, and general industrial ventilation. They are commonly installed in manufacturing plants, woodworking facilities, metal fabrication shops, chemical processing environments, and commercial HVAC mechanical systems requiring reliable, low-leakage airflow conduits.
