在熔管的时候，先用PPR管剪刀切好ppr管。切割时要把管子断面尽量剪平，没有毛边和毛刺，管材和管件连接端面必须清洁，干燥、无污染，否则会影响熔接效果。并在管材熔接口标上熔接深度线。
When melting the pipe， first cut the PPR pipe with PPR pipe scissors. When cutting，静安区PVC管业， the cross-section of the pipe Try to cut it flat without burr and burr. The connecting end face of the pipe and fittings must be clean， dry and pollution-free，PVC管业品牌， otherwise the welding effect will be affected. And the welding depth line is marked on the pipe welding joint.
相对于其他PP管材，PP-R管材的突出优点是既改善了PP-H的低温脆性，又在较高温度下(60℃)具有良好的耐长期水压能力，特别是用于热水管使 用时，长期强度均较PP-H和PP-B好。
Compared with other PP piPES，PVC管业， the outstanding advantage of PP-R pipe is that it not only improves the low temperature brittleness of pp-h， but also has good long-term water pressure resistance at higher temperature (60 ℃). Especially when it is used for hot water pipe， the long-term strength is better than pp-h and pp-b.
In addition to the wall thickness， we can also distinguish from the color marking on the outer wall of PPR pipe. Color marking is also called coextrusion. The PPR hot water pipe is marked with red color marking， the PPR cold water pipe is marked with blue color marking， and there are also manufacturers who do not need any color marking for PPR cold water pipe.
