The differences between PPR pipes and stainless steel pipes
PPR water pipe
　　As the mainstream plumbing material today, PPR pipes can be used for both cold‑water and hot‑water applications in everyday life. Their joints are joined using a heat‑fusion process, creating a seamless bond between pipe sections. Consequently, once installed and pressure‑tested, they do not suffer from the aging‑related leaks that can occur over time with aluminum‑plastic composites. While PPR plastic itself is non‑toxic, it lacks self‑cleaning and antibacterial properties. Over prolonged use, the material may become a breeding ground for secondary water contamination and bacterial growth, posing a serious threat to human health.
Stainless steel water pipe
　　Stainless steel is a well‑recognized, biocompatible material that can be safely implanted in the human body and is widely used as a water‑supply pipe in developed Western countries. In these nations, stainless‑steel piping has enjoyed many years of successful application and has become the prevailing trend and direction of development. Stainless steel is safe and non‑toxic, exhibits exceptional stability, offers outstanding corrosion resistance, does not contaminate water quality, and helps maintain pure, hygienic water—ensuring complete compliance with health and safety standards. As such, it is the ideal choice for direct‑drinking water lines. With the growth of the national economy and rising living standards, thin‑walled stainless‑steel pipes and fittings have emerged as a new paradigm in the evolution of domestic water‑distribution systems.
