Shenyang ventilation pipeline How to install it correctly?

1. Make preparations before construction

As the saying goes, "sharpening the knife will not hurt the firewood cutter". Adequate preparation is the prerequisite to ensure the quality of the air duct device. When preparing for the manufacturing of purification air duct, whether centralized manufacturing in the factory or on-site manufacturing, the site shall be kept clean and sealed, and the lighting and lighting conditions shall meet the conditions. In addition, the fabricated square tubes should be stopped guarding to prevent pollution as far as possible.

2. Selection of duct material

The selection of air duct materials also has a great impact on the construction quality of air ducts. Generally speaking, in order to ensure the weight of air duct, it is necessary to use thick air duct, but in addition, it is also necessary to comprehensively consider the size and pressure level of air duct. From the design point of view, it is worth noting that a system can have several duct plate thicknesses corresponding to different static pressure levels at the same time.

3. Horizontal connection of air duct

The horizontal connection of the air duct is particular, which can be said to be a wrist to maintain the length of the air duct, and also has the function of strengthening the stiffness and adhering to the horizontal size of the air duct. Usually, angle steel flange is used for horizontal connection, which depends on the wall thickness, more on the connection type and the plate wall reinforcement method.

4. Longitudinal seam joint of air duct

The longitudinal joint mode of air duct can be selected according to the practical situation. Buckle seaming is often used in medium and low pressure air ducts. For rectangular air ducts, there is no pressure level when combined with seaming, so the use of buckle seaming can save a flanging process. At present, most of the longitudinal seam joints of air ducts use buckle seaming. For vertical seams and cover type vertical seams, rivets, self tapping screws, spot welding, embossed dents and other methods can be used for fastening.

5. Storage of air duct

The prefabricated air duct shall be stored well to avoid secondary pollution. Seal the pipe orifice with plastic cloth and other sealing materials, and then stack the air ducts in categories. Before using the air duct, pay attention to stop the cleaning work, make sure that the surface of the plate is free of corrosion, and do not dust after it is dry.
