Contact us to explore the right solution for your duct manufacturing needs. A spiral ducting machine is a specialized type of machinery used to create spiral ducts that are used in heating, ventilation, and air conditioning (HVAC) systems. The spiral duct is formed by feeding a tube of duct material through a set of rollers that shape the material into a spiral shape. The edges of the spiral are then joined together with specialized welding or fastening techniques. The finished spiral ducts offer superior airflow, noise reduction, and energy efficiency compared to traditional rectangular ductwork.   HS Code : 8455229090 Min.

Spiral ducts are widely used in HVAC systems due to their durability, efficiency, and streamlined design. One common question in duct installation is whether spiral ducts need to be sealed. Proper sealing plays a crucial role in maintaining energy efficiency, preventing air leaks, and ensuring optimal system performance. At Hecheng Source Machinery, we specialize in manufacturing spiral air duct machines and air duct production lines, ensuring high-quality ductwork solutions. Why Sealing a Spiral Duct is Important 1. Minimizing Air Leakage Even though spiral ducts have fewer joints compared to rectangular ducts, they can still experience air leakage if not properly sealed. Leakage reduces system efficiency and increases energy costs. 2. Enhancing Energy Efficiency Sealing spiral ducts prevents conditioned air from escaping, ensuring that the HVAC system operates at peak efficiency. This helps reduce heating and cooling expenses. 3. Improving Indoor Air Quality Unsealed ducts can allow contaminants, dust, and pollutants to enter the system, affecting indoor air quality. Proper sealing helps maintain a clean and healthy environment. 4. Preventing Condensation & Moisture Issues In high-humidity environments, unsealed ducts may lead to condensation, which can cause mold growth and damage to the duct system. Sealing prevents moisture buildup and extends duct lifespan. 5. Meeting Industry Standards Many HVAC regulations require ducts to be sealed to meet efficiency and safety standards. Compliance with these regulations ensures better system performance and longevity. How to Seal a Spiral Duct Sealing spiral ducts involves applying mastic sealant, foil tape, or using factory-sealed gasketed connections to prevent air leaks. It is recommended to inspect the duct system periodically to ensure seals remain intact.   While spiral ducts have an inherently tight structure, proper sealing is still essential to prevent air leakage, improve energy efficiency, and maintain air quality. Investing in high-quality ductwork and ensuring proper sealing enhances HVAC system performance.
