یک لوله خوب، نه تنها باید اقتصاد خوبی داشته باشد و باید یک رابط پایدار و قابل اعتماد داشته باشد، مقاومت در برابر ضربه مواد، ضد ترک خوردگی، ضد پیری، خوردگی و یک سری از مزایا، در مقایسه با لوله سنتی، سیستم تخلیه HDPE دارای زیر مجموعه ای از مزایا:
⑴ reliable connection: polyethylene pipe system between the use of electric hot melt connection, the joint strength is higher than the pipe body strength.
⑵ low temperature impact resistance: polyethylene low temperature embrittlement temperature is very low, in the -60-60 ℃ temperature range of safe use. Winter construction, due to good impact resistance of the material, will not occur tube embrittlement.
⑶ good resistance to stress cracking:HDPE Water Pipe with low gap sensitivity, high shear strength and excellent scratch resistance, resistance to environmental stress cracking performance is also very prominent.
⑷ good chemical resistance: HDPE Water Pipe can withstand a variety of chemical media corrosion, the soil exists in the chemical substances will not cause any degradation of the pipeline. Polyethylene is an electrical insulator and therefore does not degrade, rust or electrochemical corrosion; it does not promote algae, bacteria or fungi.
Nevertheless, there will be detrimental release of harmful substances.
⑸ resistant to aging, long life: containing 2.5.5% of the uniform distribution of carbon black polyethylene pipe can be stored in the open air or use for 50 years, will not be damaged by UV radiation.
⑹ good wear resistance:HDPE Water Pipe and steel pipe wear resistance comparison test shows that HDPE drain wear resistance of steel pipe 4 times. In the area of mud transport, HDPE drains have better wear resistance compared to steel pipes, which means that HDPE drains have a longer service life and better economy.
⑺ Good flexibility: The flexibility of the HDPE drain makes it easy to bend, and the project can bypass the obstruction by changing the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation cost.
⑻ low flow resistance:HDPE Water Pipe with a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and non-sticking properties ensure that HDPE drains have higher transport capacity than traditional tubing, while also reducing piping pressure loss and water consumption.
حمل و نقل آسان: HDPE لوله های آب از لوله های بتونی، لوله گالوانیزه و لوله های فولادی سبک تر، حمل و نصب آسان، نیروی انسانی پایین و نیازهای تجهیزات، به معنی هزینه های نصب شده به شدت کاهش می یابد.
⑽ a variety of new construction methods:HDPE Water Pipe with a variety of construction techniques, in addition to the traditional excavation can be used for construction, but also can use a variety of new trenchless technology such as pipe jacking, directional drilling, , Cracks and other means of construction, which is not allowed to excavate some of the places, is the only choice, so HDPE drainage applications more widely.
