The advantages and disadvantages of PPR plastic pipe and stainless steel water pipe

Stainless steel water pipe

Advantages: Stainless steel water pipe is a safe and non-toxic healthy material, which can enter the human body with great value. The inner wall of the pipeline is smooth and will not scale after long-term use. Contamination with bacteria is not easy. It does not need to worry about the impact of water quality. It can eliminate secondary pollution of water, high strength, 3 times of copper pipe, 8-10 times of plastic pipe, low thermal conductivity, good thermal insulation performance, 25 times of copper pipe, corrosion resistance, service life of up to 100 years, simple and fast construction, Lightweight, healthy, environmentally friendly, waterproof, impact-resistant, high-pressure resistant, low-flow, easy for engineering maintenance and replacement.

Disadvantage: high manufacturing cost.

Stainless steel is a material that can be directly implanted into the human body. The health and environmental benefits are undeniable. Therefore, stainless steel water pipes have long been widely used in some developing countries such as Japan, Germany, the United States, the United Kingdom, and Italy.

Japan is the country that likes to use stainless steel water pipes the most, with a ratio of more than 95%. All residential areas are equipped with stainless steel drinking water pipes, and the direct drinking water on the streets of Japan also uses stainless steel water pipes. Friends who have been to Japan should have seen or drank it. Stainless steel water pipes have greatly improved the water quality and avoided secondary pollution. , to improve the earthquake resistance. In contrast, the current utilization rate of stainless steel pipes in developing countries is relatively low, generally only suitable for group enterprises and high-end villas.

PPR plastic pipe

As a new type of water pipe material, PPR plastic pipe has the unique advantages of sanitation and non-toxicity. Its material consists entirely of carbon and hydrogen elements. Light weight, density 0.89-0.91g/cm3. Pressure and corrosion resistance. The inner wall of the pipe is smooth and the resistance is small. It can be used as both a cold water pipe and a hot water pipe. The PPR pipe interface adopts hot melt technology. After the hot melt connection, the pipe can be connected with the pipe fitting at the interface, and the integrity is good. It is no problem to install and pressure test qualified PPR plastic pipe for 25-35 years.

Advantages: moderate price, stable performance, thermal insulation, corrosion resistance, impermeability, service life up to 25-35 years.

Disadvantages: It is easy to accumulate dirt and moss on the inner wall for a long time, which can easily lead to secondary pollution of water. There is also the need for special connection tools. The connection surface needs to be heated. If the heating time is too long or the socket is plugged in too much, the water flow will be blocked.
