    Matters on Air Duct Production Line

    Dimensions outside rectangular ducts and diameters outside circular ducts are calculated. The ventilation pipes are made of thin steel plate, galvanized steel plate or aluminium plate and stainless steel plate with a thickness of 0.5-2MM. It has little influence on the size after deployment, so it can be neglected when deploying lofting, but for the air duct with special wall thickness and missing, when the wall thickness of the common plate is greater than 2MM, the influence of the wall thickness must be considered. That is to say, for the unfolding and blanking of the circular air duct, the calculation of the diameter should be based on the medium diameter, and for the rectangular air duct, the air duct should still be based on the air duct. External dimension expansion.

    How big the market for ventilation ducts is

    On the market research , the natural climate change indicates that our demand for ventilation ducts is increasing, ventilation ducts as a part of many electrical appliances, the market demand is very large. The possibility of using ventilation ducts in the future is very great unless new products have been developed to completely replace the use of ventilation ducts. Ordinary thin plate version is more convenient to process and has good performance, but it is easy to rust. Galvanized steel sheet is mainly coated with zinc on the surface of ordinary steel sheet, which helps to prevent rust and can be used in humid environment. Aluminum alloy plate is easy to process, and has corrosion resistance, explosion-proof lamp performance, in line with a variety of ventilation systems. Stainless steel plate also has good corrosion resistance, cold resistance, acid resistance, etc., in many environments can be used.
