The advantages and impact of "Dongguan Spiral Duct"?
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 1 ~ 1.5m; and only one pipe connection is needed to connect two spiral ducts, while the connection of traditional rectangular ducts often requires a completely independent double flange system. 1 Standardized products. The production of fittings (pipes and joints) for spiral air ducts has been highly automated, systematic and has industrial quality control. 2 Low installation cost. The installation time of the circular duct system is only 1/3 of the similar rectangular duct. 3Usually requires less installation space. Without increasing any pressure drop, a round pipe with a diameter of 200 mm in the same installation space can replace a 250 x 150 mm rectangular pipe. Without adding additional installation space, several parallel circular pipes can replace flat rectangular pipes. Taking all factors into account, in most cases, circular pipes take up less space than rectangular pipes. For the same pressure characteristics, the installation space of several round pipes is often the same or less than that of a rectangular pipe. Many rectangular piping systems require a 4-bolt system for installation, thus increasing 40 ~ 80mm in all directions of the pipeline. 4 Pressure reduction: It is well known that the wind resistance of a circular duct is much smaller than that of a rectangular duct. 5 Precision bite molding process: The molds used in imported equipment are all special steel structures. Even after three or five years of use, the surface of the pressing mold remains the same, so that the surface of the galvanized steel sheet is not damaged and greatly extended. The service life of the air duct is improved, and the joints are even and flat, the mouth is tight, the connection force is strong, and the seal is good. Spiral duct is the most widely used type of pipe in today's society. It mainly plays a role of ventilation and air supply. It is a spiral-shaped thin-walled pipe made of metal tape rolls. It does not need to be welded. The spiral air duct is round. It is mostly used in air supply, bulk material transportation, and replaces traditional white iron pipes (that is, hand-sewn iron pipes). The spiral air duct is a type of air duct. No manual tapping required.
