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. 標(biāo)準(zhǔn)化的產(chǎn)品。

2. Standardized products.

螺旋圓管配件(管件、接頭)的生產(chǎn)已高度自動化、系統(tǒng)化，質(zhì)量控制已工業(yè)化。

The production of spiral pipe fittings (pipe fittings, joints) has been highly automated and systematic, and the quality control has been industrialized.

3.較低的安裝成本。

3. Low installation cost.

圓形風(fēng)管系統(tǒng)的安裝時間僅為類似矩形風(fēng)管系統(tǒng)的1 / 3。

The installation time of circular duct system is only 1 / 3 of that of similar rectangular duct system.

4. 通常只需要很小的安裝空間。

4. Usually only a small installation space is required.

在相同的安裝空間內(nèi)，一個200mm直徑的圓管可以代替250mm直徑的管，而不增加任何壓降× 150mm矩形管。在不增加安裝空間的前提下，可以用幾根平行的圓管代替扁的矩形管。考慮到所有因素，在大多數(shù)情況下，圓形管所占用的空間小于矩形管。對于相同的壓力特性，幾根圓形管道的安裝空間往往等于或小于一個矩形管道的安裝空間。很多矩形管道系統(tǒng)在安裝時需要4個螺栓系統(tǒng)，所以在管道的各個方向都增加了40-80mm。

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. 減壓:眾所周知，圓形風(fēng)管的風(fēng)阻要比矩形風(fēng)管的風(fēng)阻小得多。

5. Decompression: as we all know, the wind resistance of circular air duct is much smaller than that of rectangular air duct.

6. 精密的咬口成型工藝:進(jìn)口設(shè)備使用的模具為特殊鋼結(jié)構(gòu)。即使使用了三、五年，壓模表面保持不變，使鍍鋅鋼板表面不受損壞，風(fēng)管的使用壽命大大延長。同時接頭均勻，夾緊，連接力強，密封性好。

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. 安全密封圈防漏系統(tǒng)。

7. Safety sealing ring leak proof system.

8. 精美的螺旋壓筋工藝，使螺旋風(fēng)管具有優(yōu)異的承受壓力的強度。增加螺旋肋后，咬邊縫厚度是管體的4倍，管道的剛性非常大，顯示出堅固性的優(yōu)點。可承受很大壓力載荷而不變形，材料厚度可減少15%，降低成本。

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. 在相同截面積下，長寬比為1:3的矩形風(fēng)管周長比螺旋風(fēng)管長40%;同樣，由于螺旋風(fēng)管的周長較短，保溫材料也可相應(yīng)減少。

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. 管道布局美觀，立體感強:當(dāng)管道須作為一種建筑特色暴露出來時，優(yōu)雅成型的法蘭風(fēng)管將是合適的選擇。

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.
