The installation of the Dongguan spiral duct
significantly reduced the connection points between the duct and the pipe, and minimized the leakage of the joints of the pipe. The typical spiral duct length is 3-6m, while the length of a typical rectangular duct is only 1 ~ 1.5m; and only one joint is needed to connect two spiral ducts, while the traditional spiral duct connection often requires a completely independent double flange system.
The production of spiral duct accessories (pipe fittings and joints) has been highly automated, systematic and has industrial quality control. The installation time of the spiral duct system is only 1/3 of the similar rectangular duct.
Pressure reduction: As we all know, the wind resistance of spiral duct is much smaller than that of rectangular duct.
Precise bite molding process: The molds used in imported equipment are all special steel structures, and the surface of the pressing mold remains unchanged, so that the surface of the galvanized steel sheet is not damaged, and the service life of the spiral duct is greatly extended. At the same time, the seam is even and flat, the mouth is tight, the connection is strong, and the seal is good. Dongguan spiral wind pipe
series equipment, the newly developed roll-screw type spiral duct machine uses hydraulic roll-shearing method to cut, so that its cuts are flat and free of burrs. The cutting process is non-sparking, noise-free and safer. The use of fixed molds makes the pipe dimensions more accurate and uniform, and the process of air duct processing is more stable and rapid. It is more convenient to change the molds of different sizes, and then adjust the angle of the thin steel plate flange ventilation ducts. The angle is adjusted by electric means, which is flexible and accurate.
