Description
PP is a kind of semi-crystalline material. It is harder than PE and has a higher melting point. Due to the high crystallinity, the surface of the material is stiff and resistant to scratch characteristics very well. PP doesn’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 lightweight, has good chemical stability, heat resistance, insulation, high mechanical strength, and is 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 takes over: used in petroleum, chemical, chlorine alkali, dye, agriculture, food, medicine, light industry, metallurgy, wastewater treatment, water supply, 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 m
- 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 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.
- l 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 the PP duct is about 70 degrees, and the thermal conductivity of this product is only 1200 to that of steel pipe, so it has better heat preservation performance.
