Large-diameter spiral steel pipes - 219mm~3020mm

One of the primary reasons for the extensive use of large-diameter hot-dip galvanized spiral steel pipes in industrial ventilation is their structural integrity. The large diameter allows for a higher volume of air to be transported efficiently, which is crucial in large - scale industrial settings such as factories, power plants, and warehouses. These facilities often generate large amounts of heat, dust, and potentially harmful gases. The spiral welding process employed in manufacturing these pipes creates a robust and uniform structure. This construction method distributes the mechanical stress evenly across the pipe wall, enabling the pipes to withstand the pressure variations and mechanical vibrations that are common in ventilation systems. For example, in a large - scale chemical plant, where the ventilation system needs to continuously remove corrosive fumes, the large-diameter pipes can maintain their shape and functionality without deformation or leakage, ensuring a safe and healthy working environment for employees.
