风管是用于空气输送和分布的管道系统。风管加工的风管有复合风管和无机风管两种。可按截面形状和材质分类有螺旋风管和矩形风管。风管制作不锈钢风管制作是在咬口缝、铆钉缝、法兰翻边四角等缝隙处涂上密封胶，涂密封胶前应表面尘土和油污。
Duct is a piping system for air delivery and distribution. The air duct processed by air duct includes composite air duct and inorganic air duct. Spiral duct and rectangular duct can be classified according to section shape and material. Air duct fabrication Stainless steel air duct fabrication is to apply sealant on seaming seams, rivet seams, flange flanging corners and other joints, and remove dust and oil stains on the surface before applying sealant.
螺旋风管的安装显着地减少了管与管之间的连接点，使管件结合部的泄漏减少到程度，典型的螺旋风管长度是3~6m，而典型的矩形风管的长度只有1~1.5m；且连接两个螺旋风管只需一个管接件，而传统的矩形风管的连接则常常需要一个完全独立的双法兰系统。
The installation of spiral air duct significantly reduces the connection points between pipes and reduces the leakage at the joint of pipe fittings to a certain extent. The typical spiral air duct is 3-6m long, while the typical rectangular air duct is only 1-1.5m long; The connection of two spiral air ducts only requires one pipe connector, while the connection of traditional rectangular air ducts often requires a completely independent double flange system.
螺旋风管的配件的生产已高度自动化、系统化，并具有工业化的质量控制。螺旋风管系统的安装时间只有相类似的矩形管道的1/3。大家都知道螺旋风管的风阻比矩形风管的风阻要小得多。
The production of spiral air duct fittings has been highly automated and systematic, and has industrialized quality control. The installation time of spiral air duct system is only 1/3 of that of similar rectangular ducts. As we all know, the wind resistance of spiral air duct is much smaller than that of rectangular air duct.
精密的咬口成型工艺：进口设备所采用的模具均为特种钢材结构，即使使用了三五年，其压制模具的表面仍保持不变，使得镀锌钢板的表面不受损伤，大大的延长了螺旋风管的使用寿命，同时接缝均匀平整、咬口紧密、连接力强、密封性好。
Precise seaming forming process: the molds used by imported equipment are all of special steel structure. Even after three or five years of use, the surface of the pressing mold remains unchanged, making the surface of galvanized steel plate not damaged, greatly extending the service life of spiral air duct. At the same time, the joint is even, flat, the seaming is tight, the connection force is strong, and the sealing is good.
螺旋风管安装的时候，要求吊架的螺孔应采用机械加工，且在设备安装后，不会有变形；其支、吊架间距，长为5米和3.75米，不能超过这个范围。如是垂直设备，那么其间距不能大于4米；如是水平设备，假如直径或长边尺寸不大于400毫米，那么其间距不能大于4米；假如直径或长边尺寸大于400毫米，那么其间距不能大于3米。
When installing the spiral air duct, it is required that the screw hole of the hanger shall be machined, and there shall be no deformation after the equipment is installed; The spacing between supports and hangers is 5m and 3.75m, which cannot exceed this range. If it is vertical equipment, its spacing shall not be greater than 4m; For horizontal equipment, if the diameter or long side size is not greater than 400mm, the spacing shall not be greater than 4m; If the diameter or long side size is greater than 400mm, the spacing shall not be greater than 3m.
