PPR热水管使用注意事项

文章出处:本站责任编辑:Admin人气:发表时间:2017/11/23 9:45:59【
 1、在使用时应该正确识别PPR管的质量:正宗的PPR管应该通过国家ISO9001和ISO14001认证的;而假的PPR管道的性能和管件的性能是无法通过上述标准。另外假冒的PPR管其使用的年限在15年,而正宗的PPR管使用年限均在50年。 
 
2、使用时注意管道总体C系数的确定:一般场合,且长期连续使温度<70℃,可选C=1.25;在重要场合,且长期连续使用温度≥70℃,并有可能较长时间在更高温度运行,可选C=1.5; 用于冷水(≤40℃)系统,选用PN1.0~1.6MPa管材、管件;用于热水系统选用≥PN2.0MPa管材、管件。 
 
PPR管在施工时应该注意哪些问题?
 
一般来说应该注意以下问题: 
 
PPR管不如金属管道的质量,在施工的时候应该要注重保护,避免不适当的外力造成PPR管损伤。在暗敷后要标出管道位置,以免装修的时候第二次破坏管道。 
 
PPR管在冬季施工的时候要小心,切管时要用锋利刀具缓慢切割。对已安装的管道不能重压、敲击,必要时对易受外力部位复盖保护物。 
 
PPR管长期受到紫外线的照射很容易老化,因此安装在户外或阳光直射处必须包扎深色防护层。
 
PPR管的连接雷电竞app下载除了法兰等机械连接雷电竞app下载外,其余均应采用热熔连接,使管道一体化,无渗漏点。
 
PPR管明敷或非直埋暗敷布管时,必须按规定安装支、吊架。
 
PPR管在使用和施工的时候一定要注意以上这些,只有注意了以上这些,才能避免PPR管发生损伤。
