    PE燃气管国际上把PE燃气管的材料分为PE32、PE40、PE63、PE80、PE100五个等级,而用于燃气管和给水管的材料主要是PE80和PE100。我国对聚乙烯管材专用料没有分级,这使得国内聚乙烯燃气管和给水管生产厂家选择原材料比较困难,也给聚乙烯管材的使用带来了不小的隐患。

      因此国家标准局在GB/T13663-2000新标准中作了大量的修订,规定了给水管的不同级别PE80和PE100对应不同的压力强度,并且去掉旧标准中的拉伸强度性能,而增加了断裂伸长率(大于350%),即强调基本韧性。

      PE燃气管执行标准:GB 15558.1-2003

      燃气用PE管材是传统的钢铁管材、聚氯乙烯燃气的换代产品。

      燃气管必须承受一定的压力,通常要选用分子量大、机械性能较好的PE树脂,如HDPE树脂。LDPE树脂的拉伸强度低,耐压差,刚性差,成型加工时尺寸稳定性差,并且连接困难,不适宜作为给水压力管的材料。但由于其卫生指标较高,LDPE特别是LLDPE树脂已成为燃气管的常用材料。LDPE、LLDPE 树脂的熔融粘度小,流动性好,易加工,因而对其熔体指数的选择范围也较宽,通常MI在0.3-3g/10min之间。

      PE燃气管产品特点

      良好的卫生性能:PE管加工时不添加重金属盐稳定剂,材质无毒性,无结垢层,不滋生细菌,很好地解决了城市饮用水的二次污染。

      卓越的耐腐蚀性能:除少数强氧化剂外,可耐多种化学介质的侵蚀;无电化学腐蚀。

      长久的使用寿命:在额定温度、压力状况下,PE管道可安全使用50年以上。

      较好的耐冲击性:PE管韧性好,耐冲击强度高,重物直接压过管道,不会导致管道破烈。

      可靠的连接性能:PE管热熔或电熔接口的强度高于管材本体,接缝不会由于土壤移动或活载荷的作用断开。
