1.螺旋風管的安裝大大減少了管道之間的連接點，減少了管件連接處的泄漏。典型的螺旋風管長度為3 ~ 6m，而典型的矩形風管長度僅為1 ~ 1.5m;連接兩個螺旋風管只需要一個連接器，而傳統的矩形風管往往需要一個完全獨立的雙法蘭系統。
1. The installation of spiral air duct greatly reduces the connection points between pipes and reduces the leakage at the connection of pipe fittings. The length of typical spiral air duct is 3 ~ 6m, while the length of typical rectangular air duct is only 1 ~ 1.5m; Connecting two spiral air ducts requires only one connector, while traditional rectangular air ducts often require a completely independent double flange system.
2. Standardized products.
The production of spiral pipe fittings (pipe fittings, joints) has been highly automated and systematic, and the quality control has been industrialized.
3. Low installation cost.
圓形風管系統的安裝時間僅為類似矩形風管系統的1 / 3。
The installation time of circular duct system is only 1 / 3 of that of similar rectangular duct system.
4. Usually only a small installation space is required.
In the same installation space, a 200mm diameter round pipe can replace a 250mm diameter pipe without increasing any pressure drop × 150mm rectangular pipe. On the premise of not increasing the installation space, several parallel circular tubes can be used to replace the flat rectangular tubes. Considering all factors, in most cases, circular tubes occupy less space than rectangular tubes. For the same pressure characteristics, the installation space of several circular pipes is often equal to or less than that of a rectangular pipe. Many rectangular pipe systems require four bolt systems during installation, so 40-80mm is added in all directions of the pipe.
5. Decompression: as we all know, the wind resistance of circular air duct is much smaller than that of rectangular air duct.
6. Precise biting forming process: the mold used by imported equipment is of special steel structure. Even if it has been used for three or five years, the die surface remains unchanged, so that the galvanized steel surface is not damaged, and the service life of the air duct is greatly extended. At the same time, the joint is uniform, clamped, with strong connection force and good sealing.
7. Safety sealing ring leak proof system.
8. The exquisite spiral reinforcement technology makes the spiral air duct have excellent strength to bear pressure. After adding spiral ribs, the thickness of undercut joint is 4 times that of the pipe body, and the rigidity of the pipe is very large, showing the advantage of firmness. It can bear great pressure load without deformation, and the material thickness can be reduced by 15% to reduce the cost.
9. Under the same cross-sectional area, the perimeter of rectangular duct with length width ratio of 1:3 is 40% longer than that of spiral duct; Similarly, due to the short circumference of the spiral duct, the insulation material can be reduced accordingly.
10. The pipeline layout is beautiful and has a strong three-dimensional sense: when the pipeline must be exposed as an architectural feature, the elegant flange air duct will be the appropriate choice.
