Ventilation Pipe

Spiral duct is a round, thin-wall metal duct formed by spiral seam without welding. It features a smooth surface, tight construction, and excellent sealing performance. It is widely used in industries such as textile, paper making, chemical, electronics, etc., for dust collection, fume extraction, and exhaust systems.

Diameter: φ75mm–φ2500mm

Length: 3M–6M (custom lengths available beyond 6M)

Wall Thickness: 0.5–2.0mm

Corrosion Resistance: Salt spray resistance up to 240 hours

Custom Designs: Special sizes and shapes can be manufactured upon request

Welded ducts are commonly used in industrial and commercial HVAC systems. They are made of galvanized or stainless steel sheets and offer high strength and corrosion resistance. Ducts can be customized based on specific air flow and pressure requirements.

Available types:

SS201 Stainless Steel Welded Duct

SS304 Stainless Steel Welded Duct

SS316L Stainless Steel Welded Duct

Galvanized Welded Duct

Carbon Steel Welded Duct

Film-Coated Stainless Steel Welded Duct

Rectangular Welded Duct with Angle Steel Flange

TDF ducts use flange connections integrated into the duct ends, connected via bolts and clips, ensuring reliable sealing and connection strength. They are widely used in HVAC systems for industrial, commercial, and residential buildings.

Key Features:

Strong and secure connection

Customizable dimensions

Smooth surface and high air tightness

Easy installation, suitable for supply and exhaust systems

Good acoustic properties, reduces noise transmission

Material Options:

Galvanized Steel: 0.5–1.5mm thickness, 1250mm or 1500mm width

SS304 Stainless Steel: 0.5–1.2mm thickness, 1220mm or 1500mm width

SS316L Stainless Steel: 0.5–1.2mm thickness, 1220mm or 1500mm width

Standard Duct Sizes:

1160mm × 1250mm (L × W)

1410mm × 1500mm (L × W)

This type of duct uses angle steel flanges for connections and consists of flanges, sealing gaskets, and ducts. Available in carbon steel and stainless steel. Sealing materials include rubber and silicone, ensuring tight joints. Ideal for use in basement ventilation, medium-to-high-pressure air systems, kitchen exhaust, and dust removal systems.
