How to distinguish the quality of PPR pipe

Look at the pipe material.

The inner and outer surfaces of the PPR pipe should be smooth and smooth, without surface defects such as dents and bubbles, so as to ensure that the water flow is unimpeded and free of scale.

It is also an effective method to test the quality of water pipes by using a hot melt machine to compare the smell and smoke produced during the hot melt process.

After the PPR pipe is melted into a liquid, it is still very clean and has a very light smell; if you smell a pungent smell or smoke, you can basically conclude that the material is impure, and it is likely to be adulterated with toxic and harmful recycled plastic.
