板的厚度对风道的质量有很大影响。为了确保空气管道的重量,使用具有小厚度的管道,但是选择青岛新风系统过程与管道的尺寸和压力水平有关。在中国,大多数金属管道都是热浸镀锌钢板和钢带。基体为冷轧低碳结构钢板,抗拉强度> 270,伸长率> 24%,厚度允许差d。 = 0.6-1.2mm(±0.07-0.13mm),因为中国的工业技术和检测技术与国外有一定的差距,国内使用的管道厚度比国外标准大20%,但与中国的经济技术同不断发展,国内许多厂家已经能够生产出厚度均匀的板材。因此,在选择风道的小厚度时,须选择误差范围小的钢板以避免浪费钢。另外,从设计的观点来看,值得注意的是,系统可具有对应于不同静压水平的若干管道厚度。在正压空气管道系统的末端或在负压空气管道的前端处,可以使用低压空气管道,并且可以在风力涡轮机附近使用中压或高压空气管道。
