The polypropylene PP air duct can be fully formed, and has the characteristics of overall structural function, good sealing function, acid and alkali resistance, etc., and can be used as a pipeline for conveying acid and alkali gases. The mechanical equipment has less investment, low cost and high power. Large diameter or square PP air ducts can be produced manually. Compared with PVC duct, PP duct has 4 advantages:

PP air duct

1. No corrosion: pp air duct can accept high concentration acid and alkali corrosion at various temperatures from 1 to 14. Wear-resistant and non-scaling: The inner wall of PP pipes and fittings is lubricated, with small resistance flow and no scaling. Vibration and noise reduction: It has good sound insulation, which can significantly reduce vibration and noise caused by liquid activity.

2. Anti-freezing and anti-cracking: PP material has excellent elasticity, so that the cross-section of pipes and fittings can expand with the frost heave liquid without cracking. Polypropylene material is a poor thermal conductor that reduces condensation and heat loss. The device is brief. The pp air duct is light in weight, easy to install and operate, and can be welded.

3. Long life: The expected life of the PP pipe system under specific operating conditions is 50 years. The pp air duct has a long service life and can be used for more than 50 years at rated temperature and pressure. It has excellent corrosion resistance, can withstand the corrosion of most chemical products, and can withstand high-concentration acid and alkali corrosion of pH1~14.

4. Good wear resistance: When conveying pulp, the wear resistance of PP pipe is 4 times higher than that of steel pipe. The pp air duct has a good molecular hygiene function, only contains carbon and hydrogen elements, is non-toxic and tasteless, and has a reliable hygiene function. It has the characteristics of heat resistance, heat preservation and energy saving. The high temperature is around 95 degrees Celsius. The thermal conductivity of the product is only 1200 times that of the steel pipe, and it has a good thermal insulation function. The connection function is reliable. Its hot melt interface strength is higher than the pipe body, and the joint will not crack due to soil movement or load.

PP air duct has strong ventilation capacity; stable acid resistance, alkali resistance, corrosion resistance, temperature resistance, prevent secondary chemical reaction between the medium in the pipe and the pipe body, and reduce the difficulty of industrial waste gas and liquid purification; PP air duct can be Directly connected with the flange, the installation is simple, convenient and fast, which greatly improves the installation power. PP plastic air duct is used for exhaust treatment of corrosive gas in workshop, and has good construction function. PP has a light pipe, the device is easy to replace, and the comprehensive project cost is low.
