1. Raw material: PPR pipe is made of polypropylene, which has excellent heat resistance, pressure resistance and corrosion resistance. PVC pipe is made of polyvinyl chloride, which is relatively cheap and has poor performance in high temperature and high pressure environment.
2. Usage: PPR pipe is often used for the installation of domestic water supply pipes and hot and cold water pipes because of its good health and safety performance and high temperature resistance. The sanitary and safety performance of PVC pipes is relatively poor, which is mainly used for cold drainage pipes and is not suitable for conveying drinking water or high-temperature water.
