Six advantages of PE drainage pipe
由于其自身独特的优点 ， 被广泛的应用于建筑给水 ,建筑排水,埋地排水管,建筑采暖、燃气输配、输气管,电工与电讯保护套管、工业用管、农业用管等 用途中 。 Due to its unique advantages , PE drainage pipes are widely used in building water supply , building drainage, buried drainage pipes, building heating, gas transmission and distribution, gas transmission pipes, electrical and telecommunications protection casing, industrial pipes, agricultural pipes And other uses . 优点 ，与传统的管材相比， HDPE排水管有以下特点： Good pipelines are not only economically applicable, but also have a series of advantages such as stable and reliable interfaces, impact resistance, aging resistance, and corrosion resistance . Compared with traditional pipes, HDPE drainage pipes have the following characteristics:
PE排水管的 连接可靠： PE 管道系统之间采用电热熔方式连接，接头的强度高于管道本体强度。 1. Reliable PE drainage pipe connection: PE piping systems are connected by electrothermal fusion, and the strength of the joint is higher than the strength of the pipe body.
PE排水管的 低温抗冲击性好： PE排水管 的低温脆化温度极低，可在 -60-60℃温度范围内安全使用。 2. PE drainage pipe has good low temperature impact resistance: The low temperature embrittlement temperature of PE drainage pipe is extremely low, and it can be safely used in the temperature range of -60-60 ° C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle.
PE排水管的 抗应力开裂性好：具有低的缺口敏感性、高的剪切强度和优异的抗刮痕能力，耐环境应力开裂性能也非常突出。 3. PE drainage pipe has good resistance to stress cracking: it has low notch sensitivity, high shear strength, and excellent scratch resistance, and it also has outstanding environmental stress cracking resistance.
PE排水管的 耐化学腐蚀性好：管道可耐多种化学介质的腐蚀，土壤中存在的化学物质不会对管道造成任何降解作用。 4. PE drainage pipe has good chemical resistance: the pipe can withstand the corrosion of various chemical media, and the chemical substances in the soil will not cause any degradation to the pipe. 是电的绝缘体，因此不会发生腐烂、生锈或 电化学腐蚀现象；此外它也不会促进藻类、细菌或真菌生长。 PE is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote the growth of algae, bacteria or fungi.
PE排水管 耐老化，使用寿命长：含有 2-2.5％的均匀分布的碳黑的 PE 管道能够在室外露天存放或使用 50年，不会因遭受紫外线辐射而损害。 5. PE drainage pipe is resistant to aging and has a long service life: PE pipes containing 2-2.5% uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
PE排水管的 耐磨性好：管道与钢管的耐磨性对比试验表明，管道的耐磨性为钢管的 4倍。 6. The wear resistance of PE drainage pipe is good: The comparison test of the wear resistance of pipe and steel pipe shows that the wear resistance of pipe is 4 times that of steel pipe .
PE排水管材才会拥有现在的城建地位，我国高速发展的经济形势下，PE管材必将拥有更广阔的前景。 It is because of these many advantages that PE drainage pipes will have the current urban construction status. Under the rapid economic development of China, PE pipes will have a broader prospect.
