CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The exhaust duct is available in galvanized steel, stainless steel, and aluminum. For corrosive or high-humidity environments, stainless steel grades 304 or 316L are recommended. The choice of material depends on the specific application and environmental conditions.
Standard nominal diameters range from 100 to 1000 mm, wall thicknesses from 0.8 to 3.0 mm, and lengths from 1000 to 6000 mm. Custom lengths are available. These are reference values; exact dimensions should be confirmed with the manufacturer for your specific model.
The duct is designed for continuous operation at temperatures from -40°C to 200°C, with peaks up to 250°C. The operating pressure range is 1.0 to 1.6 MPa. These values are based on standard specifications and must be verified for the actual application.
Corrosion resistance is verified through salt spray testing per ASTM B117, with a minimum duration of 500 hours. This test ensures the duct can withstand corrosive environments. Always confirm the specific corrosion resistance requirements with the manufacturer.
