不仅能够经济适用， 还 有稳定可靠的接口、抗冲击、抗老化、耐腐蚀等一系列的优点，与传统的管材相比， HDPE 非开挖穿越管 有以下特点： PE non-excavation crossing pipe is not only economically applicable, but also has a series of advantages such as stable and reliable interface, impact resistance, aging resistance and corrosion resistance. Compared with traditional pipes, HDPE non-excavation crossing pipe has the following characteristics:
非开挖穿越管 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. The connection of PE non-excavation through pipes is reliable: PE pipe systems are connected by electrothermal fusion, and the strength of the joint is higher than the strength of the pipe body.
非开挖穿越管 的低温抗冲击性好： PE 非开挖穿越管 的低温脆化温度极低，可在 -60-60℃温度范围内安全使用。 2. PE non-excavation crossing pipe has good low temperature impact resistance: The low-temperature brittleness temperature of PE non-excavation crossing pipe is extremely low, and it can be used safely 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.
非开挖穿越管 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 non-excavation pipe has good resistance to stress cracking: it has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also outstanding.
非开挖穿越管 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 non-excavation pipe has good chemical corrosion resistance: the pipeline can withstand the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipeline. 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.
非开挖穿越管 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 non-excavation 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.
非开挖穿越管 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. PE non-excavation pipe has good abrasion resistance: a comparative test of the abrasion resistance of pipes and steel pipes shows that the abrasion resistance of pipes is 4 times that of steel pipes .
非开挖穿越管 材才会拥有现在的 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 precisely because of these many advantages that PE will have its current status through non-excavation through pipes. Under the rapid economic development of China, PE pipes will have a broader prospect.
