产品简介

 PE输水管的分子量

较高的分子量导致较高的聚合物粘度,不过粘度也与测试所用的温度和剪切速率有关。用流变或分子量测量对材料的分子量进行表征。HDPE的品级一般具有的分子量范围是40 000~300 000,重均分子量大致与熔融指数范围相对应,即从100~ 0.029/10min。通常地,更高的MW(更低的熔融指数MI)增强了熔体强度、更好韧性和ESCR,但是更高MW使加工过程更难或且需要更高的压力或温度。分子量分布(MWD):PE的WD根据使用的催化剂和加工过程而有从窄到宽的不同。

最常用的MWD测量指数是不匀度指数(HI),它等于重均分子量(MW)除以数均分子量(Mn)。所有HDPE品级的这个指数范围是4—30。窄MWD 提供了在模塑过程中的低翘曲性和高冲击性。中到宽MWD提供了对多数挤塑过程的可加工性。宽MWD也可改进熔体强度和抗蠕变性。

 

PE输水管技术参数:

长度:直管长度一般为6m、9m、12m,也可由供需双方商定。长度的极限偏差为长度的+0.4%,-0.2%。盘管长度一般为200米/盘(限dn50以下口径)

耐温范围:-25-80℃,常温下使用

耐压范围:0.6-1.6MPa,耐高压一般不超过16公斤,一般非为5个压力等级:6公斤   8公斤   10公斤   12.5公斤   16公斤

连接方式:机械连接   热熔对接   电热熔连接

执行标准:GB/T 13663-2000《给水用聚乙烯(PE)管材》。

颜色:市政饮用水管材的颜色为蓝色或黑色,黑色管上应有共挤出蓝色色条。色条沿管材纵向至少有三条。其他用途水管可以为蓝色和黑色。暴露在阳光下的敷设管道(如地上管道)必须是黑色。

应用范围:给水,农田灌溉,穿线管,民用输水,疏浚抽沙,燃气输送,瓦斯抽放等。

PE给水管产品特点

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1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,不会导致管道破裂。

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。

良好的施工性能:管道质轻,焊接工艺简单,施工方便,工程综合造价低。

 

315PE给水管的连接方式:

电热熔接性:采用电热熔焊机将直管与直管、直管与管件连接起来。一般多用于140mm以下管。

热熔对接连接:采用的对接焊机管道连接起来,一般多用于140mm以上管。

钢塑连接:可采用法兰、螺纹丝扣等方法连接。

为方便施工和保证施工质量、还应准备相应的工具。
