The selection of ventilation pipe material also has a great impact on the construction quality of the pipe. Generally speaking, in order to ensure the weight of the pipeline, the pipeline with smaller plate thickness is required, but the size and pressure level of the pipeline need to be comprehensively considered. From a design point of view, it is worth noting that a system can have several pipe thicknesses corresponding to different static pressure levels at the same time. The transverse connection of air duct has certain stress. This connection method can be said to be a means to extend the length of the air duct, and also has the function of enhancing the rigidity and maintaining the transverse size of the air duct. Generally, the transverse connection method is angle steel flange connection. This connection mode depends on the wall thickness, the connection type and the plate wall reinforcement mode. The prefabricated air duct needs to be stored to avoid secondary pollution. The pipe orifice can be sealed with sealing materials such as plastic cloth, and then the air ducts can be stacked by categories. Before using the pipeline, please pay attention to the cleaning operation, confirm that the plate surface is free of corrosion, and do not clean it after drying.
