A good pipe, not only should have a good economy, and should have a stable and reliable interface, material impact resistance, anti-cracking, anti-aging, corrosion and a series of advantages, compared with traditional pipe, HDPE drainage system has the following A series of advantages:
â''kual sambungan: sistem paip polietilena antara penggunaan sambungan cair panas elektrik, kekuatan bersama lebih tinggi daripada kekuatan badan paip.
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.
⑼ easy handling:HDPE Water Pipe than concrete pipes, galvanized pipe and steel pipe lighter, it is easy to carry and install, lower manpower and equipment needs, means that the installation costs greatly reduced.
â'½ pelbagai kaedah pembinaan baru: HDPE Water Pipe dengan pelbagai teknik pembinaan, selain penggalian tradisional boleh digunakan untuk pembinaan, tetapi juga dapat menggunakan berbagai teknologi trenchless baru seperti jacking pipe, penggerudian arah, , Keretakan dan lain-lain cara pembinaan, yang tidak dibenarkan menggali sesetengah tempat, adalah satu-satunya pilihan, jadi aplikasi saliran HDPE lebih meluas.
