The wind cabinet manufacturer tells you that the production of spiral round air duct pipe fittings, connectors and other products has been highly intelligent and systematic, and has modern quality operation. The equipment price is low, and the equipment time of the circulating air duct system only needs one third of the same rectangular pipe. Only a small amount of equipment is required. Under the condition of not increasing the small pressure drop, within the scope of similar equipment, the round pipe with a diameter of 200 mm can replace the rectangular pipe with a diameter of 250 times 150 mm. Without increasing the scope of other equipment, several parallel round tubes can replace a flat rectangular tube.
Considering all factors, in many cases, the area occupied by circular tubes is smaller than that of rectangular tubes. For similar pressure characteristics, the equipment range of several circular pipes is often similar to or lower than that of a rectangular pipe. When rectangular tubes are used as equipment, most of them require a four bolt system, so 40-80mm is added in all directions of the tubes.
All of these have been removed. The wind resistance of round duct is much smaller than that of rectangular duct. Detailed biting forming process: the models of foreign imported machinery are all special steel structures. Even if the limited model is used for 3-5 years, the appearance will remain unchanged for a long time, so that the appearance of the galvanized steel plate will not be damaged, and the service life of the air duct will be greatly improved. The joints are uniform and neat, with strong bite force and good sealing performance. The safety seal ring is a leak proof system.
