由于矩形框风管的四角易造成渗流，降低了合理载流总面积，不锈钢板风管的气体流通性好，合理载流总面积大，不锈钢板风管提供商，因此 不锈钢板风管的二次噪音小，304不锈钢板风管，由于不锈钢板风管的抗压强度大，因而风管震动造成的低频噪音更小，空气想法能好，管理体系损耗小，日常运作管理体系用电量少。现阶段还很有可能采用扁卵形风管来着陆风管的占有室内空间高度，扁卵形风管是将不锈钢板风管用尤其的机器设备将圆形风管经撑拉定形生产加工成扁卵形。由于风管的两侧是圆形，因此 气旋坚固，风管的刚度好，露出设备美观大方性好，是较为想象的风管系列产品。
The four corners of rectangular frame air duct are easy to cause seepage, which reduces the reasonable total current carrying area. The stainless steel plate air duct has good gas circulation, large reasonable total current carrying area, and the stainless steel plate air duct supplier. Therefore, the secondary noise of stainless steel plate air duct is low. The 304 stainless steel plate air duct has high compressive strength, so the low-frequency noise caused by the air duct vibration is smaller, the air idea is good, and the management system loss is small, The daily operation management system uses less electricity. At this stage, it is also very likely to use the flat oval air duct to achieve the indoor space height of the land air duct. The flat oval air duct is to use special machinery and equipment to pull and shape the round air duct into a flat oval shape. Because the two sides of the air duct are round, the cyclone is solid, the air duct has good stiffness, and the exposed equipment is beautiful and generous. It is a more imaginative air duct series product.
螺旋式椭圆形风管螺旋风管采用热轧带钢带条状管料，根据风管成形机一次咬出咬口骨形，并沿螺旋式渐开线齿轮运动轨迹叠成圆形管形，另外将咬口缝卡紧，终采用尤其的机器设备将圆形风管经撑拉定形生产加工成扁卵形。客户可根据需要的长短激光切割而成。不锈钢板风管的生产制造高度积化，生产制造速率迅速，另外采用规模化生产制造跟规范化生产制造，促使椭圆形不锈钢板风管的生产制造法律效力大大的发展，性强。
Spiral oval air duct The spiral air duct adopts the hot rolled steel strip pipe material. According to the air duct forming machine, the seam bone shape is bitten out at one time, and is folded into a circular pipe shape along the spiral involute gear movement path. In addition, the seam seam is clamped tightly. Finally, the circular air duct is processed into a flat oval shape by special machine equipment through stretching and shaping. The customer can cut it by laser according to the length required. The production and manufacturing of stainless steel plate air duct is highly integrated, and the production and manufacturing speed is rapid. In addition, large-scale production and standardized production and manufacturing are adopted, which promote the development of the legal effect of the production and manufacturing of oval stainless steel plate air duct.
由于不锈钢板风管采用螺旋形压槽，因而较为等同于规格型号的白铁皮风管，其抗压强度要高。
As the stainless steel plate air duct adopts spiral groove, the compression strength of the galvanized air duct which is equivalent to the specification and model is higher.
当气体根据管路开展传送的过程中，由于圆上设立螺旋式型咬缝，提升风管的抗压强度，不容易造成震动，因而在着陆低频噪音传送上，存有的隔音不良影响，很有可能合理的着陆了壁厚传播声音，发展修建品行。有研究表明，一样采用D200，薄厚为26#厚钢板生产制造的碰角管与螺旋钢管，由于螺旋钢管的弯曲刚度高过碰角管，其低频段比后面一种低3~10dB，中高频率段低12~20 dB。在相仿风管横截面、风管材料薄厚类同的前提条件下，在低频段椭圆形不锈钢板风管的隔音性好于矩形框风管10dB上下。
In the process of gas transmission according to the pipeline, since the spiral undercut is set on the circle to improve the compression strength of the air duct, it is not easy to cause vibration. Therefore, there is a good sound insulation effect on the transmission of low-frequency landing noise, which is likely to reasonably land the wall thickness to transmit sound and develop the construction practice. Research shows that the angle impact pipe and spiral steel pipe manufactured with D200 and 26 # thick steel plate are the same. Because the bending stiffness of spiral steel pipe is higher than that of angle impact pipe, its low frequency band is 3~10dB lower than that of the latter, and its medium and high frequency band is 12~20dB lower. On the premise of similar cross section of air duct and similar thickness of air duct materials, the sound insulation of oval stainless steel plate air duct at low frequency is 10 dB higher than that of rectangular frame air duct.
