Spiral ducts are shaped like spirals and offer numerous advantages such as a smooth appearance, fewer connection points, easy installation, low air resistance, and minimal noise. They are widely used in various fields, primarily for tasks like air distribution, cold air supply, exhaust of smoke and dust, conveying bulk materials, and more. Spiral ducts come in a variety of sizes, with common thickness ranging from 0.3 to 1.2 mm, width of 125mm, and length of 3-6m. Custom sizes are available for special requirements. Let's take a closer look at the specifications and dimensions of spiral ducts. What is a spiral duct?
Spiral ducts are thin-walled pipes formed by rolling metal strip into a spiral seam, circular in shape, and without welding. They are commonly used for air distribution and bulk material conveyance, capable of replacing traditional galvanized iron pipes (i.e., hand-seamed iron pipes) and are widely used in the market as ventilation ducts.
