1, PPH plastic pipe connection is reliable: Polyethylene piping system between the use of electric melting method connection, the joint strength is higher than the main strength of the pipeline.
2, PPH plastic pipe, low temperature impact resistance: Polyethylene low temperature embrittlement temperature is very low, can be used in the temperature range of -60-60 degrees Celsius safe. In winter construction, because the material has good impact resistance, it will not crack brittle pipe.
3 、 good stress cracking resistance: PPH has low notch sensitivity, high shear strength and excellent scratch resistance, and it also has outstanding environmental stress cracking resistance.
4, good chemical corrosion resistance: PPH pipe corrosion resistant variety of chemical medium, the presence of soil chemical substances will not cause any degradation of pipeline. Polyethylene is an electrical insulator and therefore does not cause decay, rust or electrochemical corrosion; in addition, it does not promote the growth of algae, bacteria, or fungi.
5, aging resistance, long service life: 2-2.5% containing evenly distributed carbon black polyethylene pipes, outdoor outdoor storage or use for 50 years, will not suffer from ultraviolet radiation damage.
6, good wear resistance: PPH plastic pipe and steel pipe abrasion resistance comparative test shows that the wear resistance of PPH pipe is 4 times of steel pipe. In the field of slurry transportation, the PPH pipe has better wear resistance than the steel tube, which means that the PPH pipeline has longer service life and better economic performance.
7, flexible good: flexible pipe which makes PPH easy to bend, engineering by changing the direction of pipeline way around obstacles, on many occasions, reduce consumption and reduce the cost of installation to pipe flexible pipe.
8, the flow resistance is small: PPH pipe has a smooth inner surface, and its Manning coefficient is 0.009. The smooth appearance and non adhesion characteristics ensure that the PPH pipeline has higher conveying capacity than the traditional pipe, and also reduces the pressure loss and energy consumption of the pipeline.
