How to choose ppr tube

First, look at the color; Generally speaking, PPR plastic pipes sold in the market are white, gray, green and yellow. Generally, gray pipes have the best quality, weak light transmission and are not easy to breed microorganisms such as bacteria. However, with the development of science and technology, color is no longer the standard to distinguish the quality of PPR pipes. You can feel the smoothness, fineness and symmetry of the tube by hand. Rough pipes are not recommended as water supply pipes, and green scale-free pipes are recommended for domestic water supply.

Second, smell the smell; Good pipes have no smell, while poor pipes have a strange smell, probably mixed with polyethylene or other waste recycling materials.

Finally, observe; Once lit, this method is the most intuitive and effective. PPR plastic pipes mixed with recycled materials and other impurities in raw materials will emit black smoke and have a pungent smell. Good materials will burn without black smoke, and the smell is pure and not pungent. Some people make mistakes when judging PPR plastic pipes. They think that it is not good for PPR plastic pipe to crack in cold weather, but in fact, PPR plastic pipe itself is brittle at low temperature, generally around-10 degrees, which reduces flexibility and enhances rigidity. Under the impact of external force or overload, the pipeline may break directly. Bring inconvenience to the construction. To this end, the relevant national norms have made clear requirements on this issue. The production standard of PPR plastic pipe GB/T 18742 is specified in detail.
