Description

The square PP air duct is also called polypropylene plastic air duct, which is used for exhaust gas exhaust in the laboratory. The square PP duct is usually used as the main duct and branch duct with the PP circular duct. The square PP air duct is made of PP sheet through a bending machine, four times of 90-degree elbows, and then hot-melt welding. There are many processes. Compared with square ducts, the price of square ducts is higher for round ducts with the same circumference or cross-section. Of course, it also depends on the wall thickness of the square PP duct and whether it is reinforced by the outer flange.

Features of square PP duct

• No corrosion: The square PP duct can withstand the PH value in a wide temperature range, ranging from 1 to 14 high concentrations of acid and alkali corrosion.
• Wear-resistant and non-scaling: PP ducts and duct fittings have uniform and smooth inner walls, with low flow resistance and no scaling.
• Reduce vibration and noise: PP duct has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.
• Anti-freeze cracking: PP material has excellent elasticity so that the ducts and pipe sections can expand with the frost heaving liquid without cracking.
• Anti-condensation, low heat loss: PP material is a poor heat conductor, which can reduce condensation and reduce heat loss.
• Simple installation: PP ducts are light in weight, easy to install and operate, and are weldable.
• Long service life: PP piping system has a service life of up to 50 years under specified conditions of use. Long service life—–PP pipeline can be used safely for more than 50 years under rated temperature and pressure conditions.
• Excellent corrosion resistance—–It can withstand the corrosion of most chemicals, and can withstand the corrosion of high-concentration acids and alkalis with a pH value of 1-14 in a wide range.
• Excellent abrasion resistance-the abrasion resistance of PP ducts is more than 4 times that of steel pipes when transporting ore slurry.
• Good hygiene performance—–PP duct material has only carbon and hydrogen elements in its molecule, which is non-toxic and tasteless, and has reliable hygiene performance.
• Heat-resistance, heat preservation and energy saving—–PP duct material has a maximum operating temperature of about 95 degrees. The thermal conductivity of this product is only 1200 that of steel pipe, so it has better heat preservation performance.
