PP air ducts are widely used for their excellent corrosion resistance, so how should customers choose the wall thickness when purchasing PP air ducts?
First of all, the wall thickness of the square PP duct depends on the application of the PP duct. In depth, the main factor affecting the wall thickness of the PP duct is the design wind speed in the duct, but in reality, few companies design by the wind speed. The wall thickness of the PP air duct is given, but the wall thickness of the PP air duct is designed according to the cross-sectional area (length, width) of the air duct.
PP square air duct 200×200 4mm
PP square air duct 320×250 4mm
PP square air duct 500×320 5mm
PP square air duct 630×400 5mm
PP square air duct 800×500 6mm
PP square air duct 1000×630 8mm
PP square air ducts are widely used in rooms with low floor heights. For rectangular structures, in addition to choosing a thicker wall thickness, outer flanges need to be reinforced. Since the ventilation system is negative pressure exhaust, there is no PP reinforced with outer flanges. If the wall thickness of the air duct is not enough, there will be the possibility of concave deformation.
Besides, what is the wall thickness of the PP air duct with a circular structure? PP round air ducts are simple. Those with a diameter of more than 400 are all formed pipes with a wall thickness of -3-5mm. The circular structure is relatively firm. . General experience is as follows:
ø500 5-5.5mm
ø550 5-6mm
ø600 5-6mm
ø700 5-6mm
ø800 6-8mm
ø1000 6-8mm
ø1200 6-8mm
ø1500 8-12mm
Specifically, it can be processed and produced according to the actual needs of customers.
