Matters on Air Duct Production Line
Feb 19,2020.
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.
