ppr管安装的小窍门

ppr管材管件连接时，PPR水管，应在墙壁上表上记号和位置，方便日后管道的维修，ppr水管品牌，尽量避免管子暴露在外面，以免受碰撞而损坏。

ppr管冷水和热水管需要分开槽来安装。

Tips for PPR tube installation

When connecting PPR pipes and fittings， marks and place should be marked on the wall to facilitate future pipeline maintenance， and the pipes should not be naked to the outside to ***oid damage caused by collision.

PPR pipe cold water and hot water pipe need separate tank to install.

PPR管施工后须经试压验收后方能封管和使用。PPR管安装主要采用热熔管件，熔接时间和压力不好掌握，工艺随机性较大，在热熔推接过程中易产生堆料从而减小通径，并使熔接处成为不规则的缺陷区，ppr水管价格，产生应力集中，影响PPR管价格的长期性能；对于PPR管的电熔连接，由于电熔丝主要采用促进PPR降解的铜，会加速PPR管的老化。

PPR pipe can be sealed and used only after pressure test and acceptance.The PPR pipe is mainly installed with hot-melt pipe fittings. The welding time and pressure are not well mastered，奉节ppr水管， and the process is random. In the process of hot melt push welding， it is easy to generate stacking materials to reduce the diameter， and make the fusion joint become an irregular defect area， which produces stress concentration， which affects the long-term energy of price of PPR pipe; For the electric melting connection of PPR pipe， the aging of PPR pipe will be accelerated because copper is mainly used to promote the degradation of PPR.

同种规格的PPR热水管壁厚要比冷水管的厚，简单举例：D25×2.3 D25×2.8 D25×3.5 D25×4.2 这里列举的是外径为25MM的PPR管所对应的四种不同规格，前面两种为冷水管，后面两种为热水管，因此可以非常明显的看出，冷水管的壁厚要小于热水管。

The wall thickness of PPR hot water pipe of the same specification is thicker than that of cold water pipe. Simple example: D25 × 2.3 D25 × 2.8 D25 × 3.5 D25 × 4.2 here are four different norms of PPR pipe with outer diameter of 25 mm. The first two are cold water pipes and the latter two are hot water pipes. Therefore， it is very clear that the wall thickness of cold water pipe is ***aller than that of hot water pipe.
