(1)、連接簡單

(1), simple connection.

螺旋風管的安裝減少了管與管之間的連接點，從而使得管件結合部的泄漏能降低到低程度。而且連接兩個螺旋風管只需一個管接件，傳統的矩形風管的連接則需要完全獨立的雙法蘭系統。

The installation of spiral air duct reduces the connection point between pipe and pipe, so that the leakage of pipe joint can be reduced to a low level. Moreover, only one pipe fittings are needed to connect the two spiral ducts, while the traditional rectangular duct connection requires a completely independent double flange system.

(2)、標準化產品

(2) standardized products

螺旋風管的配件，包括管件和接頭等，其生產已經實現高度自動化、系統化，并且有工業化的質量控制。

Spiral duct fittings, including fittings and joints, have been highly automated, systematized and industrialized quality control.

(3)、安裝費用低

(3) low installation cost.

螺旋風管的安裝時間只有矩形風管的三分之一。

The installation time of the spiral duct is only 1/3 of that of the rectangular duct.

(4)、通常只需較小的安裝空間

(4) usually only requires smaller installation space.

在不增加額外安裝空間的前提下，數條平行的螺旋風管可替代矩形風管，所占用的空間也要比矩形風管少。

Without additional installation space, several parallel spiral ducts can replace rectangular ducts and occupy less space than rectangular ducts.

(5)、壓降低

(5) reduction of pressure

螺旋風管的風阻要比矩形風管的小得多。

The wind resistance of the spiral duct is much smaller than that of the rectangular duct.

(6)、精密的咬口成型工藝

(6) precise bite molding process

所采用的模具均為特種鋼材結構，即使使用幾年，壓制模具的表面仍能保持不變，鍍鋅鋼板的表面不會受損，同時，接縫均勻平整、咬口緊密、連接力強、密封性好。

The dies used are all special steel structures. Even after several years of use, the surface of the pressing dies can remain unchanged, and the surface of galvanized steel sheet will not be damaged. At the same time, the joints are even, the bites are tight, the connection force is strong and the sealing is good.

(7)、密封圈防漏系統，使用螺旋壓制楞筋工藝

(7) safety seal ring leakage prevention system, using spiral pressing rib reinforcement technology.

該工藝能使螺旋風管具有佳的承受壓力，咬口潛縫厚度是管體的四倍，增加了管道的剛性和優越性，并能承受大壓力負荷而無損傷變形。并且，用材厚度可減小15%，降低了成本。

The process can make the spiral air duct withstand pressure well, and the thickness of the undercut in the bite is four times that of the tube body. It increases the rigidity and superiority of the pipeline, and can withstand high pressure load without damage and deformation. Moreover, the material thickness can be reduced by 15% and the cost is reduced.

(8)、保溫用材少

(8) less insulation materials

由于螺旋風管周長短，保溫用材也可相應減少。

Because the circumference of the spiral duct is short, the material for thermal insulation can also be reduced correspondingly.
