Here is what all you must know about Spiral Duct

The spiral duct is a strong spirally wound tube. The leading and certified Spiral Duct Manufacturers in India supply all types of ducts. However, those made with steel metal are highly durable. These days most often galvanized steel, stainless steel, aluminum, and copper are used for making different types of ducts. This process has female ends, therefore, to connect two spirals duct sections a male coupler needs to be used as a connection piece. 

• Ducts and fittings, like couplings, bends, t-pieces, reducers, end caps, etc.

• Airflow regulation products such as air dampers, VAV, and CAV regulators.

• Sound attenuation products like sound attenuators, flexible duct connectors, and duct insulation.

• Fire protection products such as fire-rated air valves, and fire and smoke dampers.

• Suspension and fixing products like clamps, support brackets, threaded rods, self-drilling screws, rivets, and duct fittings without seals like a sealing tape.

• Finish-trim products, like air valves, diffusers, louvers, etc.

Spiral ducts are made of 137 mm and 140 mm wide spirally rolled steel sheet metal, using so-called tubeformers. These machines are for spiral air duct production. The duct manufacturer buys these metal strips or cuts them yourself so that they have an exact dimension tolerance. If that does not happen then even a small margin of error can be the reasons for the spiral duct machine to close the lockseam incorrectly. The slitting machine cuts large steel coils with a width of 1250-1500 mm into different narrower steel strips. 

The ducts are sold by Spiral Duct Manufacturers in India in 3 m lengths as a standard, though it is possible to manufacture circular ducts of any length from 0.5 to 12 m with a tolerance of up to 2 mm. Spiral ductwork is also available in diameters from 80 mm to 1600 mm – and most of the standard diameters are available from stock. The duct wall thickness comes in different ranges. It depends on the diameter and the required pressure in the ductwork. 

Spiral ducts are also manufactured by Spiral Duct Manufacturers in India from 0.4 mm to 1.8 mm thick metal sheets - where the material used is determined by the pressure and mechanical requirements of the system - and the price.

• First, find one of the trusted suppliers and Spiral Duct Manufacturers in India.

• Be specific about mentioning the size, duct’s material, and other specifications. 

• Ask for the customization if required for the ventilation process.

• Check for warranty and other certifications with customer support availability. 

• Verify what is included return policy in case of any discrepancies. 

• Compare prices across multiple platforms but prioritize quality over cost. 

• Choose only those suppliers with fast and active customer service to address queries promptly.

Always compare prices to get a better deal from all the leading suppliers.
