PE pipes and PPR pipes are two commonly used types of piping. They have certain distinctions, and in some specialized locations, both may be required simultaneously, but they cannot be directly fused; instead, a middle pipe is needed to connect them. How should we fuse PE and PPR pipes? Let's find out together through this article.

PPR pipes can be joined through hot melting, while PE pipes cannot. To connect them together, a pipe section can be used to link the two pipes. PE water pipes differ from PPR pipes, as the PE water pipes have a high stable temperature of 70℃ and a low temperature of -30℃ under normal operating conditions. PPR water pipes also have a high stable temperature of 70℃ and a low temperature of -10℃ under normal conditions. It can be observed that PE water pipes and PPR water pipes share the same high-temperature resistance, but PE water pipes have superior low-temperature performance compared to PPR water pipes.

When it comes to welding, while both PPR and PE pipes can be heat-welded, PPR pipes are easier to handle. PPR pipes have smooth, rounded edges, whereas PE pipes have irregular edges, which are more prone to clogging. The welding temperatures also vary, with PPR pipes requiring 260℃ and PE pipes needing 230℃.

From the perspective of low-temperature impact strength, PE pipe material excels in terms of indicators. PPR pipes have higher strength than PE pipes, while PE pipes are more flexible than PPR pipes.
