1. The materials are different. The material of the PVC pipe is made of polyvinyl chloride, and the PPR is made of copolymerized polypropylene, so the appearance of the two is different. PVC is generally milky white, and PPR can add other pigments, thus turning into colorful color pipes.
2. the wall thickness is different. If the diameter of PVC is 6 mm, the wall thickness is generally about 2 mm. If the diameter is 8~10 mm, the wall thickness generally reaches 2.5 mm. The PPR pipe is divided into 4 pipes and 6 pipes, and the wall thickness is 2.3 mm and 3.5 mm, respectively. 3. If we want to distinguish, it can be distinguished by the label on the pipe, and under the same pipe diameter, the pipe wall of the PPR pipe should be slightly thicker.
3. the cost is different. This is because their material and wall thickness are different, so the production cost and price are also different. In comparison, the price of PPR is higher.
4. The last difference is that the use is different because the safety and hygiene of PVC is not as good as that of PPR pipes. Home improvement generally chooses PPR as water supply, and can also be used for the installation of hot and cold water pipes. PVC pipes are generally used as drainage pipes, and can only be used as cold water pipes.
