PP is a kind of semi crystalline material. It is more hard than PE and has a higher melting point. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP don't have the problem of environmental stress cracking. Moreover, it could offer significant resistance to any chemical or acid. PP pipe is a kind of plastic pp made of copolymerized polypropylene resin and extruded. It has light weight, good chemical stability, heat resistance, insulation, high mechanical strength and non-toxic.At present, the PP pipe connection mode widely used in construction is:1. welding sleeve socket welding method   2End edge welding method.  3. dissimilar material take over: used in petroleum, chemical, chlorine alkali, dye, agriculture, food, medicine, light industry, metallurgy, waste water treatment, water supply and drainage, etc.


PP duct performance characteristics

  • No corrosion: PP air duct can withstand the PH value in a wide temperature range, ranging from 1 to 14 high concentrations of acid and alkali corrosion.

  • 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.

  • Reduce vibration and noise: PP air duct has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

  • 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.

  • Anti-condensation, low heat loss: The material used in the PP duct is a poor thermal conductor, which can reduce condensation and reduce heat loss.

  • Simple installation: PP air duct is light in weight, easy to install and operate, and has weldability.

  • 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.

  • Excellent corrosion resistance: It is resistant to 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.

  • Good hygiene performance: PP air duct material has only carbon and hydrogen elements in its molecular structure, which is non-toxic and tasteless, and has reliable hygiene performance.

  • Heat-resistant, heat-preserving and energy-saving: The maximum operating temperature of PP duct is about 70 degrees, and the thermal conductivity of this product is only 1200 of that of steel pipe, so it has better heat preservation performance.
