PE(聚乙烯)材料由于其强度高、耐腐蚀、无毒等特点,被广泛应用于给水管制造领域。因为它不会生锈,所以,是替代普通铁给水管的理想管材。PE给水管执行产品国家标准:GB/T 13663.1-2017、GB/T 13663.2-2018《给水用聚乙烯(PE)管道系统第2部分:管材》。
压力等级:0.4MPa~1.6MPa
规格型号:dn20mm~dn1200mm
执行标准: GB/T13663.2-2018《给水用聚乙烯(PE)管材》。
性能特点:
1.密度小,重量轻,容易搬运和安装;
2.可耐多种化学介质腐蚀;
3.水力性能优越,其磨阻系数仅为0.009;
4.使用寿命长,可达50年以上;
5.连接可靠;
6.高韧性,抗震性能好;
7.较好的抵抗慢速裂纹增长(SCG)和快速裂纹扩展(RCP)的能力。
聚乙烯为惰性材料,除少数强氧化剂外,可耐多种化学介质和微生物侵蚀,不同温度和介质浓度下HDPE材料对常见的化学介质的抗腐蚀性能如下表:
规格尺寸:PE80级与PE100级给水用聚乙烯(PE)管材规格尺寸符合下表要求。
