Description
The PP square plastic pipes are also called polypropylene plastic air ducts, which are 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 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 it is reinforced by the outer flange.
Features of PP square plastic pipe
- 1. No corrosion: The PP large plastic rectangular duct can withstand the PH value in a wide temperature range, ranging from 1 to 14 high concentrations of acid and alkali corrosion.
- 2. Wear-resistant and non-scaling: rectangular polypropylene pipes and pipe fittings have uniform and smooth inner walls, with low flow resistance and no scaling.
- 3. Reduce vibration and noise: rectangular polypropylene pipes have 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: rectangular polypropylene pipes are light in weight, easy to install and operate, and weldable.
- 6. Long service life: PP polypropylene square ventilation ducting 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, and can withstand 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 rectangular polypropylene pipes is more than 4 times that of steel pipes when transporting ore slurry.
- 9. Good hygiene performance—–rectangular polypropylene pipe 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—–rectangular polypropylene pipe 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.
