PPR管格与管件连接端面必须清洁、干燥、无油。
用卡尺和合适的笔在管端测量并标绘出热熔深度，热熔深度应符合下表规定：
熔接弯头或三通时，按设计图纸要求应注意其方向，朝阳区ppr水管，在管件和管材的直线方向上，用辅助标志标出其位置。
The connecting end face of PPR pipe lattice and pipe fittings must be clean， dry and oil-free.
Measure and plot the hot melt profundity at the pipe end with a caliper and a suitable pen. The hot melt profundity shall meet the requirements of the following table:
When welding elbows or tees， the direction could be noted according to the requirements of design drawings， and the place shall be marked with auxiliary marks in the straight direction of pipe fittings and pipes.
三种PP管材中，PPR水管，管材抗冲击性能PP-Rgt;PP-Bgt;PP-H，ppr水管价格，管材热变形温度PP-Hgt;PP-Bgt;PP-R，管材刚 性PP-Hgt;PP-Bgt;PP-R，管材常温温度PP-Hgt;PP-B和PP-R，管材耐化学腐蚀性PP-Hgt;PP-B和PP- R。
Among the three kinds of PP pipes， the impact resistance PP-R gt; PP-B gt; pp-h， the thermal deformation temperature pp-h gt; PP-B gt; PP-R， the rigidity pp-h gt; PP-B gt; PP-R， the normal temperature pp-h gt; PP-B and PP-R， and the chemical corrosion resistance pp-h gt; PP-B and pp-r.
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，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， 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，热水管ppr， 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.
