Flange plate duct engineering throughout the construction process 80% of the workload at the factory by the complete processing machinery and equipment by the process [package scraped material, shape, commissure and spell Angle, sealed, cleaning, duct hangers hanging bars production). Construction site, leaving only the duct work connected with the hoisting of Hengshui supply a total of flange duct, site construction tool simple and easy to install. Compared with conventional pipe flange angle of Hengshui supply air duct flange plate, flange plate duct easy to install, saving time and labor and material. When designing the ventilation system of Hengshui supply a total of flange duct, should try to reduce the pressure loss of the system. When the total amount of losses and pressure ventilation system is large, it can be divided into small systems. Flow velocity in the pipe should not be too high, so as not to cause noise regeneration. Determining co-plate inner flange ventilation duct air velocity should be selected according to the different requirements of the relevant provisions. Here to tell us about methods to reduce noise.
