PE安全燃气管道采用燃气专用聚乙烯生产，规格、尺寸及性能符合GB15558.1-2003、GB15558.2-2005标准的要求。管道具有柔韧性好、耐腐蚀性强、质轻、抗冲击性能优良等特点，管道系统采用热熔对接、电熔等连接方式，管材、管件熔为一体，系统安全可靠，施工成本低，在实际应用中发展迅速。大力推广PE燃气安全管道，符合国家建设部、国家经贸委发展化学建材的指导方针，符合人们生活水平提高的发展需要。
♦ 较强的耐腐蚀性
♦ Stronger corrosion resistance
聚乙烯为惰性材料，除少数强氧化剂外，可耐多种化学侵蚀，无电化学腐蚀，无需做防腐层。
PE belongs to inert material, and it can resist erosion of lots of chemical substances except few strong oxidants. It has no electrochemical corrosion and requires no corrosion resistance layer.
♦ 的韧性
♦ Unrivalled tenacity
聚乙烯燃气管肯有的柔韧性，当地算或地震发生时，能随之产生一定程度的变形而不致断裂，避免燃气泄漏，是抗地震性优异的管道。
PE gas pipe features excellent tenacity. In case of differential settlement or earthquake, it can deform to a certain extent accordingly, thus avoiding fracture and gas leakage, so it has excellent earthquake resistance.
♦ 高抵抗刮痕的能力
♦ High scratch resistance
抗刮痕能力使之适用于非挖管道的铺设和作为承插管插入旧管道中实现旧管网修复。
Scratch resistance makes it suit laying of trenchless pipe and be used as socket pipe to be inserted into old pipe to have old piping network repaired.
♦ 的抗应力开裂性
♦ Excellent stress-cracking resistance
聚乙烯管的抗应力开裂性能优于钢管，在工程应用中可以大小减少管道的泄漏和爆管几率，增加燃气输送的安全性。
Stress-cracking resistance of PE pipe is better than that of steel pipe. PE pipe can reduce pipe leakage and explosion probability and increase gas transportation safety.
♦ 长久的使用价值
♦ Long-term service
聚乙烯管材的环向抗拉强度已被长期静液压实验所证实，使用寿命长。地埋管在-20℃-40℃温度范围内安全使用50年以上。
Circular tensile strength of PE pipe has been confirmed by long-term hydrostatic test. PE pipe has long serve life, and it can be safely used for more than 50 years when buried at the temperature of -20°C to 40°C.
♦ 较大的输送流量
♦ Larger flow rate
管壁平滑，能提高介质流速，增大流量，与相同的金属管道相比，可输送更大的流量，节省动力消耗。
Smooth pipe wall of PE pipe can enhance flow speed of medium and enlarge flow amount. Compared with the same metal pipe, PE pipe can transmit larger flow and save dynamic consumption.
♦ 显著地经济效益
♦ Remarkable economic benefits
成本低，投资少，与金属管道相比，可减少工程综合投资1/3左右，可盘卷的小口径管材，可进一步降低工程造价。
The cost and investment are low. Compared with metal pipe, it can reduce overall engineering investment by 1/3. Coiled small-diameter pipe can further reduce engineering cost.
♦ 方便的施工性能
♦ Convenient construction
管道质轻，同体积PE材料仅是钢的1/8，易搬运，易弯曲，焊接工艺简单，土方量少，施工速度快捷。
