ppr管热熔操作
热熔器接通电源，到达温度指示灯亮后方能开始操作。
切割管材必须使端面垂直于管轴线，管材切割一般使用管子剪，PVC水管，如为大管径，PVC水管代理，则用锯条切割，切割后断面去毛刺和毛边。
Hot melt operation of PPR pipe
The heat melt can be operated after the power is turned on and the temperature indicator light is on.
The end face of the pipe must be perpendicular to the pipe axis. Pipe cutting is generally used. If the pipe diameter is large， it is cut with a saw blade. After cutting， the sected shall be deburring and burr free.
ppr水管打压试验
在ppr水管的水路改造好后，一定要做好打压试验。有机会需自己在现场，并且实际观察压力是否下降，我们可以在接头处裹上报纸，潜江PVC水管，有漏水可以轻松发现。不要等着水泥都铺上了，才去打压试水。
Pressure test of PPR water pipeAfter the transformation of PPR water pipe， the pressure test must be done well. If there is an opportunity， we need to be actually observe whether the pressure drops. We can wrap a newspaper around the joint and easily find the leakage. Don"t wait for the cement to be laid before you test the water.
