Advantages of PE gas pipe
PE燃气管道 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。 可靠 Reliable connection: The PE gas pipeline system is connected by electric heating , and the strength of the joint is higher than the strength of the pipeline body.
⑵ Good impact resistance at low temperature: The low temperature brittleness temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60 ° C. PE燃气管 材料抗冲击性好，不会发生管子脆裂。 During construction in winter, because of the good impact resistance of PE gas pipe material, the pipe will not be brittle.
PE燃气管 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) Good resistance to stress cracking: PE gas pipes have low notch sensitivity, high shear strength, and excellent scratch resistance. The resistance to environmental stress cracking is also outstanding.
PE燃气 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。 好 Good chemical corrosion resistance: PE gas pipelines can withstand the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipeline. Polyethylene 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燃气管道 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。 ⑸Anti-aging and long service life: PE gas pipes containing 2-2.5% of uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
PE燃气 管道与钢管的耐磨性对比试验表明， PE燃气 管道的耐磨性为钢管的 4倍。 好 Good abrasion resistance: A comparative test of the abrasion resistance of PE gas pipes and steel pipes shows that the abrasion resistance of PE gas pipes is 4 times that of steel pipes . PE燃气 管道具有更好的耐磨性，这意味着 PE燃气 管道具有更长的使用寿命和更好的经济性。 In the field of mud transportation, compared with steel pipes, PE gas pipelines have better wear resistance, which means that PE gas pipelines have a longer service life and better economy.
PE燃气 管道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用量并降低安装费用。 好 Good flexibility: The flexibility of the PE gas pipeline makes it easy to bend. In engineering, the way of the pipeline can be changed to bypass obstacles. In many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs.
PE燃气 管道具有光滑的内表面，其曼宁系数为 0.009。 小 Small water flow resistance: PE gas pipeline has a smooth inner surface, and its Manning coefficient is 0.009. PE燃气 管道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。 The smooth performance and non-adhesive characteristics ensure that the PE gas pipeline has a higher transport capacity than traditional pipes, and also reduces the pressure loss and energy consumption of the water pipeline.
PE燃气 管道比混凝土管道、镀锌管和钢管更轻，它容易搬运和安装，更低的人力和设备需求，意味着工程的安装费用的大大降低。 方便 Convenient transportation: PE gas pipeline is lighter than concrete pipeline, galvanized pipe and steel pipe. It is easy to handle and install. Lower labor and equipment requirements mean that the installation cost of the project is greatly reduced.
PE燃气 管道具有多种施工技术，除了可以采用传统的开挖方式进行施工外，还可以采用多种全新的非开挖技术如顶管、定向钻孔、衬管、裂管等方式进行施工，这对于一些不允许开挖的场所，是唯一的选择，因此 PE燃气 管道应用领域更为广泛。 ⑽A variety of new construction methods: PE gas pipelines have a variety of construction technologies. In addition to traditional excavation methods, a variety of new non-excavation technologies such as pipe jacking, directional drilling, and lining pipes can be used. , Cracked pipes, etc., this is the only option for some places where excavation is not allowed, so PE gas pipelines are more widely used.
