Spiral duct

     The installation of spiral ducts significantly reduces the number of joints between pipes, minimizing leaks at the pipe joints to a lower degree. Typical lengths for spiral ducts range from 3 to 6 meters, whereas typical rectangular ducts are only 1 to 1.5 meters long; and connecting two spiral ducts requires only one pipe fitting, whereas traditional rectangular ducts often necessitate a completely separate double flange system.

1. Standardized Products

Components for spiral round ducts (fittings and joints) are produced with high automation, systematic processes, and industrialized quality control.

2. Low installation costs

Installation time for the round duct system is only 1/3 that of similar rectangular pipes.

3. Typically requires a small installation space

Without increasing any pressure drop, a 200mm diameter circular pipe can replace a 250×150mm rectangular pipe within the same installation space. Multiple parallel circular pipes can also replace flat rectangular pipes without requiring additional installation space. Considering all factors, in most cases, the space occupied by circular pipes is less than that of rectangular pipes. For the same pressure characteristics, the installation space of multiple circular pipes is often equal to or less than that of a single rectangular pipe. Many rectangular pipe systems require a 4-bolt system for installation, thereby increasing the space by 40~80mm in all directions of the pipe.

4. Reduced Pressure Drop: The wind resistance of round ducts is significantly lower than that of rectangular ducts.

5. Precise Beak Molding Technology: The molds used in imported equipment are all made of special steel structures, which maintain their surface integrity even after three to five years of use, ensuringGalvanized Steel SheetThe surface remains undamaged, significantly extending the lifespan of the ductwork. Additionally, the seams are even and flat, the joints are tight, the connection is strong, and the seal is excellent.

6. Leakproof Safety Sealing Ring System

7. The exquisite spiral pressing rib technology enables the spiral duct to withstand pressure.AppropriateStrength is significantly enhanced with the addition of helical ribs, where the bite seam thickness is four times that of the pipe body. The pipeline's rigidity is extremely high, demonstrating robust superiority. It can withstand substantial pressure loads without damage or deformation. Material thickness can be reduced by 15%, thereby lowering costs.

8. When the cross-sectional area is the same, the perimeter of a rectangular duct with a length-to-width ratio of 1:3 is 40% longer than that of a spiral duct, saving material; similarly, due to the shorter perimeter of the spiral duct, the insulation material can also be reduced accordingly.

9. Pipe layout is aesthetically pleasing and has a strong three-dimensional feel: When pipes are required to be exposed as architectural features, elegant and tasteful formed flange ducts will beSuitableThe Choice
