Stainless steel air flow duct, the effective flow area, the intensity is high, so the wind pipe smaller low frequency noise caused by vibration, air flow system of good performance, small pressure drop, daily operation of system power consumption. At present, also can be used to reduce the flat oval duct space height wind pipe, because both sides of the wind pipe is circular, so the air duct is stable, good rigidity, good appearance is exposed installation, wind pipe series ideal. The production of stainless steel tube is the strip strip wind roll material, a bite out of the bite bone shape through the wind pipe forming machine,fengkoujiw.89ix.comjiaolianji.89ix.com fengkouji.89ix.comkangyangji.89ix.comzhamenb.89ix.com geqiangban.89ix.com and along the spiral involute trace into circular tubular, and will bite sew tightly, finally according to the need of the length of cut. Since its launch in the market, because of its excellent performance and low cost of action, it is widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airports, tunnels and other construction industry.

一般而言，通风系统的流量都很大，因此要求使用阻力较小的空气输送管道，以节省造价和运行费用——就最适用。一般情况下使用镀锌铁管，有腐蚀性及特别潮湿的场所使用不锈钢管。

Generally speaking, the ventilation system has a large flow rate, so it is necessary to use the air transmission pipeline with less resistance to save the cost and operation cost. The use of galvanized iron pipes in general, corrosive and wet places especially used stainless steel tube.
