Which is better, ppr water pipe or pe water pipe?

Under normal use, the highest stable temperature of PE water pipe is 70℃ and the lowest temperature is -30℃. In normal use, the highest stable temperature of PPR water pipeline is 70℃, and the lowest temperature is-10℃. PE pipes are as resistant to high temperature as PPR pipes. However, PE water pipe is superior to PPR water pipe in low temperature performance.

The low temperature embrittlement point of PE pipe is -70℃, which is superior to other pipes. In winter, PVC-U pipes are prone to brittle fracture in field construction. An experience gained from the pilot project of laying PVC-U buried water supply pipe in Beijing is that it is not suitable to lay PVC-U pipe when the temperature is below zero.

Difference between pe water pipe and ppr water pipe

1, welding. Although both PPR water pipes and PE water pipes can be welded by hot melt, PPR water pipes are easier to operate, and the flanging of PPR water pipes is round, while the flanging of PE water pipes is irregular and easy to block. Welding temperature is also different, PPR water pipe is 260℃, pe water pipe is 230℃.

2. Low temperature impact strength. From the index point of view, it is the strength of PE water pipe material. PPR water pipe is stronger than pe water pipe, and PE water pipe is softer than PPR water pipe.

3. The maximum size of 3.PE tube can be dn 1000, and the maximum size of PPR is dn 160. Therefore, PE pipes are mostly used for drainage pipes, and PPR is generally used for water supply pipes.
