Product Description


PP duct product introduction
XICHENG EP LTD., specializes in the production of PP air ducts, also known as polypropylene plastic air tubes and plastic ventilation pipe. PP air ducts are usually used for the exhaust of corrosive waste gas in the environment of industrial plants, the exhaust of gas in the fume hood in the laboratory, and the exhaust of VOC organic waste gas.
The advantage of PP air duct is light weight, acid and alkali corrosion resistance. It adopts PP welding rod hot-melt welding, elbows, flanges, tees, variable diameters and other supporting pipe fittings are easy to process and install. It is currently the most widely used ventilation pipe in waste gas treatment in the environmental protection industry.
Working principle of PP duct
PP air ducts are used in industrial exhaust such as acid, alkali, organic waste gas, etc. By installing induced draft fans at the end, the polluted waste gas in the environment is drawn through the PP anti-corrosion fan to be discharged outdoors. PP air ducts are usually divided into positive pressure air supply or negative pressure ventilation working modes, with smooth inner wall and low resistance.






Performance Characteristics


PP duct performance characteristics:

1. Corrosion resistance: PP ducts can withstand the PH value in a wide temperature range, ranging from 1 to 14 high concentrations of acid and alkali corrosion.
2. Wear resistance and non-scaling: The inner wall of the PP duct and pipe fittings is uniform and smooth, with low flow resistance and no scaling.
3. Reduce vibration and noise: PP air duct has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.
4. Anti-freeze cracking: The material used in the PP duct is excellent in elasticity, so that the pipe and pipe section can expand with the frost heaving liquid without bursting and cracking.
5. Simple installation: PP air duct is light in weight, easy to install and operate, and has weld ability.
6. Long service life: The PP duct has a service life of up to 50 years under the specified temperature, pressure, medium and other use conditions.
7. Heat-resistant, heat-preservation and energy-saving: The maximum operating temperature of the PP duct is about 70 degrees. The thermal conductivity of this product is only 1200 of that of the steel pipe, so it has better heat preservation performance.



Specifications


PP duct specifications
There are two types of PP ducts from the shape, one is square PP ducts, and the other is round PP ducts. From the application point of view, the amount of circular shape is relatively large. The circular PP duct is easy to manufacture. The PP sheet can be rolled into a circular tube by a plate rolling machine, and the labor and mechanical costs are relatively low. The square PP air duct is made of a PP sheet through a hot-melt bending machine, folded four times at a 90-degree angle, and then welded by a butt welding machine. Compared with square pipes with the same circumference or cross section, square pipes are more expensive and have more processes. Of course, it also depends on the wall thickness of the PP duct and whether the outer flange is reinforced.

How to select PP duct


How to select PP ducts needs to be determined according to application requirements. If it is used for exhaust gas exhaust, calculate the total air volume (m3/H) Design the flow velocity of the gas in the PP duct(m/s), divide the air flow by the flow velocity and wait until the cross-sectional area of the PP duct, after opening the root, multiply it by 2 to get the diameter of the pipe.
The calculation formula is:




Application of PP air duct in industry






Installation method of PP duct


The round pipe is connected with a collar.
PP duct sleeve connection, round and square can be customized. Convenient production, welding method for installation, firmness.
Square pipe uses flange connection.
PP duct flange connection, round and square can be customized. Need to splice flange, easy installation, screw lock, easy to disassemble and maintain.
