PPR pipes can be found in the following applications:

Water supply, sewage systems, gas supply (solvent-welded only), heat insulation, cold supply and cooling technology. Placing them underground is also possible due to their chemical resistance. PPR piping is commonly used within plumbing infrastructure for several reasons including its energy efficiency.

Besides that, it has a very long life span. It does not rust or corrode because of the material used, which is why it lasts so long, even when buried underground. The materials needed to build PPR pipes are readily available which makes them cheaper than other pipe materials such as copper.

A PPR pipe can hold its shape, which means it does not require a lot of space between joints, as would be the case with other pipes such as those made from PVC. In addition, it is not toxic, meaning it can be safely used in drinking water supply systems.
