What are the applications of the spiral air duct in Dongguan?
When it comes to checking the knowledge of air leakage in Dongguan spiral ducts, we must first realize that this is the key factor that affects whether the entire galvanized duct can be applied more effectively. So we must test it well before applying it. It is particularly important to note that when we measure the leakage of the galvanized duct at night, to ensure that the surrounding environment is dark, place a 100W low-voltage lighting lamp with a protective cover on the inside or outside of the duct. The joints are moved slowly, and the observation is made on the other side. When light is emitted, it indicates that a significant air leak is found and a record is made.
Dongguan spiral duct is used in many exhaust systems. The air-conditioning air supply pipes in the competition hall are double-layer heat-preserving circular spiral air pipes 1400mm and 1600mm, a total of 12 pieces. The overall hoisting technology of the air duct.
The layout of the spiral duct and the spherical nozzle in Dongguan 2 Construction process flow Install the duct bracket, the classification number of the duct, set up the duct assembly platform → install the duct flange → suspend the duct to the platform to assemble → measure the horizontal level of the main duct center → Measure into the center line of the exhaust air outlet → Tee opening of the air outlet → Installation and insulation of the short air duct Hanging pipe → air pipe bracket installation and adjustment.
