Metal Ducting For Dust Collection

Metal ducting for dust collection is the duct main body used in dust collection systems for conveying dust-laden gas, made of metal sheet rolled or welded, including straight pipe sections and connections. The duct transports dust-laden gas captured by the suction hood to the dust collector, and then transports clean gas from the dust collector to the fan and exhaust stack. It is suitable for duct installation in industrial dust collection systems, exhaust systems, and ventilation systems.

• Metal duct has high strength, adapting to long-distance transportation. Metal duct is made of galvanized steel, carbon steel, or stainless steel, with good rigidity, can withstand system negative pressure and positive pressure. Suitable for long-distance duct transportation; elbow and support spacing set by duct diameter.
• Smooth inner wall reduces dust deposition. Duct inner wall is flat and smooth, reducing dust adhesion and deposition on the wall. For horizontal ducts, air velocity kept at 18–25 m/s to ensure dust suspension transportation without settling.
• Flange or clamp connection, good sealing. Duct uses flange or clamp connection, with gasket or sealing ring at the interface. Flange connection is suitable for occasions requiring higher sealing; clamp connection is suitable for occasions requiring quick installation and disassembly.
• Material optional, adapting to different working conditions. Galvanized steel suitable for ambient temperature dry conditions; carbon steel suitable for general industrial dust collection; stainless steel suitable for flue gas containing corrosive components or higher temperature. Wall thickness selected by duct diameter and medium abrasiveness.
• Duct air velocity for dust-laden gas in horizontal ducts should be kept at 18–25 m/s; vertical duct velocity can be appropriately reduced. Specific value determined by dust particle size and concentration.

• Duct diameter and length designed to system layout
• Material: galvanized sheet, carbon steel, or stainless steel
• Connection: flange or clamp
• Wall thickness selected by medium abrasiveness and system pressure
• Elbow, tee, and reducer supplied as matching parts
• Support hanger and fixing parts supplied as matching parts
• Brand label customizable
• OEM/ODM: customized to dust collection system layout; customer brand on packaging

After rolling or welding, duct is checked for roundness and straightness. Flange connection surfaces are checked for flatness. Clamp connections are fit tested. Duct inner wall is checked for cleanliness. Ducts are classified and packed by specification. Third-party inspection accepted. The factory has supplied metal ducting to industrial dust collection and exhaust systems, and uses this field data to match duct material and wall thickness to flue gas temperature and dust abrasiveness.
