What is the difference between PE pipe and PPR pipe? Temperature resistance: In the state of use, the temperature of PE water pipeline can withstand 70 ℃ to minus 30 ℃. However, when the PPR water pipeline is in use, it can only withstand 70°C to minus 10°C. It can be seen from this. The high temperature resistance of PE pipes and PPR pipes is similar. Welding: Whether it is PPR pipe or PE pipe, hot melt welding can be used, but relatively speaking, PPR operation effect is more convenient. From the appearance point of view, the edge of PPR water pipe is relatively smooth, while the flange of PE pipe is irregular. , It is prone to blockage after a long time; and the welding temperature of the two is different. The welding temperature of PPR water pipe can reach 260 ℃, and the PE pipe can reach 230 ℃. Low temperature impact strength: In terms of indicators, PPR water pipes are much stronger than PE water pipes, and PE water pipes are more flexible than PPR water pipes.
