This paper introduces the use and advantages of stainless steel spiral duct. Next, we will continue to introduce spiral duct fan, mainly to illustrate its advantages, and hope that through the introduction of these two articles, readers can understand and understand the basis of spiral duct, and will not be unfamiliar with it

The installation of spiral air duct reduces the connection points between pipes and reduces the leakage of pipe joints to a low degree. The connection of two spiral air ducts only needs one pipe connection. The connection of traditional rectangular pipes requires a completely independent double flange system. The accessories of spiral pipes, including fittings and accessories, have been highly automated and systematic, And has industrial quality control

The installation time of spiral duct is only 1 / 3 of that of rectangular duct. There is no additional installation space. Several parallel spiral duct can replace rectangular duct, which takes less space than rectangular duct

The wind resistance of spiral duct is much smaller than that of rectangular duct. All dies are of special steel structure. Even after several years of service, the die surface can remain unchanged. The surface of galvanized steel sheet will not be damaged. At the same time, the joint is even and smooth, the bite is tight, the connection force is strong and the sealing is good

The process can make the spiral pipe have good pressure, the undercut can be buried 4 times the thickness of the cylinder, which increases the rigidity and superiority of the pipe body, and can bear large pressure load without damage and deformation. In addition, the material thickness can be reduced by 15% and the cost can be reduced. Due to the shorter circumference of spiral air duct, the insulation material is also reduced accordingly
