spiral ductThe installation significantly reduces the connection points between pipes, minimizing leakage at the joint of pipe fittings. The typical length of a spiral duct is 3-6m, while the typical length of a rectangular duct is only 1-1.5m. Only one pipe joint is required to connect two spiral ducts, while traditional rectangular duct connections often require a completely independent double flange system.
1. Standardized products
The production of accessories (fittings and joints) for spiral circular air ducts has been highly automated, systematic, and has industrialized quality control.
2. Low installation cost
The installation time of circular duct systems is only one-third of that of similar rectangular ducts.
3. Usually only requires a small installation space
A circular pipe with a diameter of 200mm can replace a rectangular pipe with a diameter of 250 × 150mm in the same installation space without increasing any pressure drop. Several parallel circular pipes can replace flat rectangular pipes without increasing additional installation space. Considering all factors, in the vast majority of cases, circular pipes occupy less space than rectangular pipes. For the same pressure characteristics, the installation space of several circular pipes is often the same or less than that of a rectangular pipe. Many rectangular pipeline systems require a 4-bolt system for installation, resulting in an increase of 40-80mm in all directions of the pipeline.
4. Pressure reduction: The air resistance of circular ducts is much smaller than that of rectangular ducts.
5. Precise bite forming process: The molds used in imported equipment are all made of special steel structures. Even after three to five years of use, the surface of the pressing mold remains unchanged, so that the surface of the galvanized steel plate is not damaged, greatly extending the service life of the air duct. At the same time, the joints are uniform and flat, the bite is tight, the connection force is strong, and the sealing is good.
6. Safety sealing ring leak prevention system
7. The exquisite spiral pressing rib technology enables the spiral air duct to have the best strength to withstand pressure. After adding spiral ribs, the thickness of the bite seam is four times that of the pipe body, and the rigidity of the pipeline is very high, showing its superiority in sturdiness. It can withstand the maximum pressure load without deformation, and the material thickness can be reduced by 15%, reducing costs.
8. When the cross-sectional area is the same, the circumference of a rectangular duct with a length to width ratio of 1:3 is 40% longer than that of a spiral duct, saving materials; Similarly, due to the short circumference of spiral ducts, insulation materials can also be reduced accordingly.
9. Beautiful pipeline layout and strong three-dimensional sense: When pipelines are a building feature that must be exposed, beautiful and elegant molded flange ducts will be the best choice.
