1、使用寿命长
1. Long service life
聚乙烯管材分子,具有良好的稳定性与抗老化性,在正常的工作温度与压力状况下,使用寿命可保证50年以上。
Polyethylene pipe molecules have good stability and anti-aging properties. Under normal working temperature and pressure conditions, the service life of polyethylene pipes can be guaranteed for more than 50 years.
2、耐腐蚀性
2. Corrosion resistance
聚乙烯分子结构稳定性极高,耐天然气、液化气、人工煤气等化学腐蚀,无需二次防腐蚀设备。土壤中存在的化学物质不会对管材产生任何降解作用。
Polyethylene molecular structure stability is very high, resistant to natural gas, liquefied gas, artificial gas and other chemical corrosion, no need for secondary anti-corrosion equipment. The chemical substances in the soil will not degrade the pipe.
3、良好的柔韧性聚乙烯管材是—种高韧性的管材,其断裂伸长率超过500%。聚乙烯管材的柔性使得它容易弯曲.工程上可通过改变管道走向的方式绕过障碍物,在许多场合,管道的柔性能够减少管件的用量并降低安装费用。
3. Good flexibility polyethylene pipe is a kind of high toughness pipe, its elongation at break is more than 500%. The flexibility of polyethylene pipe makes it easy to bend. In engineering, it can bypass obstacles by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings and installation costs.
4、具有优异的抗冲击、抗地震能力
4. It has excellent shock resistance and earthquake resistance
聚乙烯的低温脆化温度极低,可在-60℃~60℃温度范围内安全使用,对管基不均匀沉降具有非常强的适应能力。冬季施工时,因材料抗冲击性好,不会发生管材脆裂。
The low temperature embrittlement temperature of polyethylene is very low, and it can be used safely in the temperature range of - 60 ℃ ~ 60 ℃. It has strong adaptability to the uneven settlement of pipe foundation. In winter construction, because of the good impact resistance of the material, there will be no brittle cracking of the pipe.
5、良好的耐磨性
5. Good wear resistance
试验表明,聚乙烯管的耐磨性是钢管的4倍,特别在泥浆输送领域,与钢管相比,聚乙烯管具有更好的耐磨性。
The test shows that the wear resistance of PE pipe is 4 times of that of steel pipe, especially in the field of mud transportation, PE pipe has better wear resistance than steel pipe.
6、水流阻力小聚乙烯管材具有光滑的内表面,其曼宁系数为0.009。光滑的内表面和非粘附特性保证聚乙烯管材具有较传统管材更高的输送能力,同时也降低了管路的压力损失和输水能耗。
6. The flow resistance is small, and the polyethylene pipe has smooth inner surface, and its Manning coefficient is 0.009. The smooth inner surface and non adhesion characteristics ensure that the polyethylene pipe has a higher conveying capacity than the traditional pipe, while reducing the pressure loss and water transmission energy consumption of the pipeline.

7、良好的环保性能
7. Good environmental performance
聚乙烯管材在加工过程中不添加重金属稳定剂,材料无毒无害,是一种绿色环保的管道材料,并且聚乙烯材料本身可回收利用,不会对环境产生污染。
Polyethylene pipe is a kind of green and environment-friendly pipeline material without adding heavy metal stabilizer in the process of processing, and the polyethylene material itself can be recycled and will not pollute the environment.
8、良好的阻燃、抗静电性能 我公司专门研制开发出了阻燃、抗静电聚乙烯管材,适用于易燃易爆等特定场所。
8. Good flame retardant, antistatic performance, our company specially developed flame retardant, antistatic polyethylene pipe, suitable for flammable and explosive and other specific places.
9、安全、可靠的连接方法
9. Safe and reliable connection method
聚乙烯管材主要采用热溶或电熔连接,本质上保持接口材质、结构与管体本身的同一性,实现了接头与管材一体化,可有效地抵抗内压产生的环向应力及轴向的拉仰应力,无漏水、漏气之忧。
Polyethylene pipes are mainly connected by hot-melt or electrofusion, which essentially keeps the identity of interface material, structure and pipe body, realizes the integration of joint and pipe, effectively resists circumferential stress and axial tension stress caused by internal pressure, and has no worry of water leakage and air leakage.
10、质轻、易搬运、施工简便
10. Light weight, easy to handle and easy to construct
聚乙烯管材的比重仅为钢管的1/8,易搬运,易弯曲,焊接工艺简便迅速,工程综合造价低,具有显著的经济效益
The specific gravity of polyethylene pipe is only 1 / 8 of that of steel pipe. It is easy to handle and bend. The welding process is simple and rapid, and the comprehensive engineering cost is low. It has remarkable economic benefits
