Oval shape of Dongguan spiral duct has various advantages
The manifestation of various advantages of the oval shape of Dongguan spiral duct :
(1) Muffler performance The air flow of the elliptical spiral duct is good, and it uses a spiral mouthpiece, which increases the strength and makes the duct difficult to generate vibration. Therefore, it has a good sound insulation effect and reduces the sound transmission of the pipe wall.
(2) Highly mechanized elliptical spiral air ducts are generally made of strip steel coils, and then bite out the bone shape through an air duct forming machine, and then processed by curling, crimping, stretching, etc. Its manufacturing can achieve a high degree of automation, speed up the production speed, and the production has been standardized, so that the elliptical spiral duct is highly mechanized and integrated.
(3) The air leakage of the elliptical spiral duct with low air leakage is very good, so the leakage is small, and the pipe section itself can reach a level that does not leak. Moreover, it can be connected using flanges, so that the leakage can be reduced, thereby reducing consumption and costs, and saving energy.
(4) High intensity
The seam of the Dongguan spiral duct is circumferential, and it can crack free even under 1.5 times the pressure. It generally uses galvanized iron sheet, so it can meet the pressure requirements of general ventilation and air conditioning.
(5) The appearance is beautiful, the height of the space can be effectively reduced due to the elliptical spiral duct. Because it is round on both sides, it has no effect on the stability of the airflow and has a beautiful appearance
