PE塑料穿线管的操作注意
1、PE塑料穿线管作为阻燃塑料线管,所以它有时作为穿线管用于家居中电线的布置,要求PE塑料穿线管连接牢固,无缝隙存在。
2、在高出安装PE塑料穿线管时,应将PE塑料穿线管与墙顶固定。
3、PE塑料穿线管入线时,应与线盒用锁扣连接。PE塑料穿线管作为穿线管使用时,其中穿线数量是一定的,不能任意穿线,即直径20mm的PVC管内可穿入4根电源线。
4、直径16mm的PVC管内可穿入3根电源线。如果穿入过多的电源线会影响电源电路的正常工作,并且不利于电源线的维修。
pe穿线管有哪些优点?
(1)连接可靠:聚乙烯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。
(2)低温抗冲击性好:聚乙烯的低温脆化温度极低,可在-60—60℃温度范围内安全使用。冬季施工时,因材料抗冲击性好,不会发生管子脆裂。
(3)抗应力开裂性好:PE管材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。
(4)耐化学腐蚀性好:PE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。聚乙烯是电的绝缘体,因此不会发生腐烂、生 锈或电化学腐蚀现象;此外它也不会促进藻类、细菌或真菌生长。
(5)耐老化,使用寿命长:含有2%—2.5%的均匀分布的碳黑的聚乙烯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。
(6)耐磨性好:PE管道与钢管的耐磨性对比试验表明,PE管道的耐磨性为钢管的4倍。在泥浆输送领域,同钢管相比,PE管道具有更好的耐磨性,这意味着 PE管道具有更长的使用寿命和更好的经济性。
(7)可挠性好: PE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。
pe穿线管属于硬质塑料管吗?
pe穿线管属于软管,一般都是一卷一卷的,PC穿线管就是硬管,一般都是一捆一捆的。
pe穿线管有着很大的优点,现在也是使用非常广泛的一种穿线管。
pe电缆穿线管规格是多少?
PE电缆穿线管的规格是蛮多的,关键看你要穿的电缆的规格。小一点的外径25 32 40 大的50 60 76 89 一百多的都有的,壁厚也有不同的。要看具体的需求。
请问一下,hdpe穿线管的执行标准是什么?
HDPE穿线管执行YD/T841.2-2016实壁管。常用型号为100和150mm。厚度为6-10mm。直管弯管都可 *** 。
pe穿线管安装的时候需要注意什么?
1、电线埋墙必需穿线管,一般可选的PVC穿线管/PE穿线管:价格实惠,可弯曲,绝缘性能好。其实一般家庭选择PVC穿线管/PE穿线管就非常不错了,只是要选择结实的,简单 *** 就是用脚踩一下,不会被踩瘪的就是好的。最后提醒一下:无论使用哪种穿线管,电线在管内都不能有接头。
2、电路改造应避免死线:再好的电路质量,也难保以后会出现故障,需要更换线路,这个时候,埋墙的电线能够方便的拽出更换就显得非常重要,所以在电改施工中要避免造成日后无法拽动的“死线”。
