螺旋風(fēng)管的接縫是周向的，接縫的強(qiáng)度比徑向的直縫強(qiáng)度要高許多，所以能保證在1.5倍工作壓力下接縫處無(wú)裂開(kāi)，由于其原材料鍍鋅帶鋼與整張鍍鋅鋼板相比，較低，加上其工廠化生產(chǎn)和規(guī)格的標(biāo)準(zhǔn)化，使得造價(jià)要比矩形風(fēng)管低；另外由于其支、吊架需量少，安裝工作量少，所以總成本較低。

The joint of spiral air duct is circumferential, and the strength of the joint is much higher than that of radial straight joint, so it can ensure that there is no crack at the joint under 1.5 times the working pressure. Due to the low price of its raw material galvanized steel strip compared with the whole galvanized steel plate, and its industrialized production and standardization of specifications, the cost is lower than that of rectangular air duct; In addition, the total cost is low due to less demand for supports and hangers and less installation workload.

由于矩形風(fēng)管的四角易產(chǎn)生湍流，減少了通流面積，空氣流動(dòng)性好，通流面積大，所以產(chǎn)品的二次噪聲小，由于其強(qiáng)度大。因此風(fēng)管振動(dòng)引起的低頻噪聲小，空氣流動(dòng)性能好，系統(tǒng)壓降小，日常運(yùn)行系統(tǒng)耗電量少。

Because the four corners of the rectangular air duct are easy to produce turbulence, the flow area is reduced, the air fluidity is good, and the flow area is large, so the secondary noise of the product is small, and its intensity is large. Therefore, the low-frequency noise caused by air duct vibration is small, the air flow performance is good, the system pressure drop is small, and the power consumption of the daily operation system is small.

螺旋風(fēng)管壓制楞筋工藝精巧，讓螺旋風(fēng)管能夠承受強(qiáng)壓力，咬口潛縫厚度是管體的四倍，管道的剛性非常大，顯示出堅(jiān)固的優(yōu)越性，能承受大的壓力負(fù)荷而無(wú)損變形，用材厚度可減小百分之15。這樣就大大降低了生產(chǎn)的成本。另外，我們需要告訴大家的是濟(jì)南通風(fēng)管道加工的制作工藝是非常精的，它一般都是采用特種鋼制作而成的，因此它的質(zhì)量自然有保證，一般可以使用上好幾年的時(shí)間，同時(shí)他還能保證長(zhǎng)期使用，這樣大大延長(zhǎng)了風(fēng)管的使用壽命，對(duì)于我們的生產(chǎn)來(lái)說(shuō)有著重要的現(xiàn)實(shí)意義。

The spiral air duct has exquisite process of pressing ribs, so that the spiral air duct can withstand strong pressure. The thickness of the undercut hidden seam is four times that of the pipe body. The rigidity of the pipe is very large, showing the advantages of firmness. It can withstand large pressure load without deformation, and the thickness of materials can be reduced by 15%. This greatly reduces the cost of production. In addition, we need to tell you that the manufacturing process of Jinan ventilation pipe is very precise. It is generally made of special steel, so its quality is naturally guaranteed. It can be used for several years. At the same time, it can also ensure long-term use, which greatly prolongs the service life of the air pipe, It has important practical significance for our production.

螺旋風(fēng)管的制作是采用帶鋼帶狀卷料，通過(guò)風(fēng)管成型機(jī)一次咬出咬口骨形，并沿螺旋漸開(kāi)線軌跡卷成圓形管狀，同時(shí)將咬口縫壓緊，后按需要的長(zhǎng)度切割而成。自投放市場(chǎng)以來(lái)，因其本身性能及低廉的動(dòng)作成本，被廣泛應(yīng)用于造船、通風(fēng)、空調(diào)、凈化、橋梁除塵、機(jī)場(chǎng)、隧道等建筑行業(yè)。送冷風(fēng)和熱風(fēng)常見(jiàn)的是空調(diào)的管道，這種管道需要加保溫材料。也可內(nèi)貼保溫材料，使風(fēng)道具有螺旋形的漂亮外觀，可免吊頂，從而降低了工程造價(jià)。

The spiral air duct is made of strip steel coil, which bites out the bite bone shape at one time through the air duct forming machine, rolls it into a circular tube along the spiral involute track, compresses the bite seam at the same time, and then cuts it according to the required length. Since it was put on the market, it has been widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries because of its own performance and low operation cost. Air conditioning pipes are commonly used to supply cold air and hot air, which need thermal insulation materials. Thermal insulation materials can also be pasted inside, so that the air duct has a beautiful spiral appearance, and the ceiling can be avoided, so as to reduce the project cost.

螺旋風(fēng)管的制造高度自動(dòng)化，生產(chǎn)速度很快，一般的風(fēng)管每分鐘能生產(chǎn)20～40米，由于其原材料鍍鋅帶鋼與整張鍍鋅鋼板相比，較低，加上其工廠化生產(chǎn)和規(guī)格的標(biāo)準(zhǔn)化，使得造價(jià)要比矩形風(fēng)管低。

The manufacturing of spiral air duct is highly automated and the production speed is very fast. The general air duct can produce 20 ~ 40m per minute. Due to the low price of its raw material galvanized steel strip compared with the whole galvanized steel plate, coupled with its industrialized production and standardization of specifications, the cost is lower than that of rectangular air duct.
