Description
PP plastic square ducts also called polypropylene plastic air duct is used for exhaust gas exhaust in the laboratory. It is usually used as the main duct and branch duct with the PP circular duct. The ventilation plastic square tube is made of a PP sheet through a bending machine, four times 90-degree elbows, and then hot-melt welding. There are many processes. Compared with square pipes, the price of square pipes is higher than round pipes with the same circumference or cross-section. Of course, it also depends on the wall thickness of the square plastic pipe and whether the outer flange reinforces it.
Features of PP plastic square duct
- 1. No corrosion: The PP plastic square duct can withstand the PH value in a wide temperature range, ranging from 1 to 14 high acid and alkali corrosion concentrations.
- 2. Wear-resistant and non-scaling: PP plastic square duct has uniform and smooth inner walls, with low flow resistance and no scaling.
- 3. Reduce vibration and noise: laboratory air ventilation system pp square air duct has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.
- 4. Anti-freeze cracking: PP material has excellent elasticity so that the pipes 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.
- 5. Simple installation: PP plastic square ducts are light in weight, easy to install and operate, and weldable.
- 6. Long service life: laboratory air ventilation system pp square air duct 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.
- 7. Excellent corrosion resistance—–It can withstand the corrosion of most chemicals. It can resist the corrosion of high-concentration acids and alkalis with a pH value of 1-14 in a wide range.
- 8. Excellent abrasion resistance-the abrasion resistance of laboratory air ventilation system pp square air duct is more than 4 times that of steel pipes when transporting ore slurry.
- 9. Good hygiene performance—–PP plastic square duct material has only carbon and hydrogen elements in its molecule, which is non-toxic and tasteless and has reliable hygiene performance.
- 10. Heat-resistance, heat preservation, and energy-saving—–PP plastic square duct material have 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.
