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，PVC管材厂家，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，PVC管材，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， 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， 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.
管材管道在使用过程中热胀冷缩现象也是不可避免的。选自耐水性材料的PPR管道刚性增强，水平布管时不易下垂，增加了管线的美观，PVC管材加盟，管道的弯曲回弹性得到提高，在高温下时仍保持外形的稳定。
The phenomenon of heat expansion and cold contraction is inevitable in the use of pipe. The PPR pipe selected from water-resistant material has stronger rigidity， and it is not easy to sag during horizontal pipe laying， which increases the appearance of the pipeline， improves the bending resilience of the pipeline， and maintains the stability of the shape at high temperature.
水路改造需要改变水路方向，一定注意配件的质量，PVC管材咨询，配件牌子也要注意，避免工人以次充好，选择同品牌配件，不同厂家用料配方肯定是不同的，即使热熔到一起也会留下隐患。配件也分热水管和冷水管，记得注意。另外，还有水阀、保温棉、卡扣等配件。
