主要表现形式:受力部位不同而产生不同情况的,管材主要在搬运或施工中受外力强冲击所致。一般外表不易察觉,常出现在管件连接处,让人误认为是焊接质量问题或其他。因在外部受力,裂缝外紧内张,黄山PPR管材管件,一般还能承受2-4KG的供水压力,误以为焊接质量存在问题。有时用户在管道通水后短期内没有发现漏水线下,一段时间后才漏水。管道在连接前,PPR管材管件咨询,端部宜去掉受损部分,安装完毕及时做好管道的水压试验。

ppr水管在连接时,无旋转地把管端导入加热套管内,插入到所标志的深度,同时无旋转地把管件推到加热管上,达到规定标志处。一般地可用心中默读数字法掌握加热时间,或观察管件、管材的加热程度,当模头上出现一圈PPR热熔凸缘时,即可将管材、管件从模头上取下进行下道工序。
When the PPR water pipe is connected,PPR管材管件图片, the pipe end is led into the heating sleeve without rotation and inserted to the marked depth. At the same time, the pipe fitting is pushed onto the heating pipe without rotation to reach the specified mark. Generally, the heating time can be mastered by reading numbers in heart,PPR管材管件规格, or the heating degree of pipe fittings and pipes can be observed. When a circle of PPR hot-melt flange appears on the die head, the pipe and pipe fittings can be removed from the die head for the next process.

PPR管为什么会有低温脆性的特点?它是由单体和少量乙烯单体在加热、加压和催化剂作用下无规共聚得到的。乙烯单体随机地分布到长链中,其中乙烯单体一般控制在3-5%之间。乙烯含量和乙烯与的聚合方式决定了其具有低温脆性的特点。
Why does PPR pipe h***e the characteristics of low temperature brittleness? It is obtained by random copolymerization of monomer and a ***all amount of ethylene monomer under heating, pressure and catalyst. Ethylene monomer is randomly distributed in long chain, and ethylene monomer is generally controlled between 3-5%. The content of ethylene and the polymerization of ethylene determine its low temperature brittleness.
