2.1 Diversification of Application Fields

Plastic pipes are widely used in various fields such as construction, municipal engineering, agriculture, and industry. Their applications are extensive, covering water supply and drainage, heating systems in buildings, water supply and drainage pipelines in municipal construction, water supply and irrigation pipes in agriculture, industrial sewage pipelines, and gas and power communication sheathing pipes. In short, PVC, PE, and PPR plastic pipes have different roles in different fields. For example, PVC pipes are often used in the front-end of real estate projects, PE pipes are often used in municipal engineering, and PPR pipes mainly serve the back-end of real estate projects. These extensive downstream applications provide a solid foundation for the demand for plastic pipes, driving the continuous increase in demand for plastic pipes in home decoration, municipal engineering, gas, and other fields. PVC, PE, and PP dominate their respective applications, driving increased demand for plastic pipe materials.

2.2 Market Development Trends

Although PVC pipes still maintain a leading market position, the trend of replacing them with PE and PP pipes is becoming increasingly apparent due to the demand for high quality and environmental protection. In the early stages of the plastic pipe industry, PVC pipes occupied a place due to their unique advantages. However, with the continuous development of the industry, the market has placed more stringent requirements on the quality, performance, and environmental protection of pipes. At the same time, the domestic supply capacity of PE and PP pipe raw materials is also continuously increasing, making the trend of PE and PP pipes replacing PVC pipes even more apparent. Nevertheless, because PVC pipes still maintain their deep historical background and price advantage, they still occupy a dominant position in the market. However, with the widespread application of PE pipes and the gradual promotion of PP pipes in the field of building water supply pipes, the industry landscape is undergoing profound changes. PE pipes are expected to further expand their applications in the future and become a new favorite in the market.

In summary, the replacement of PVC pipe materials with PP and PE pipe materials will be an inevitable trend in the future development of the industry, especially the replacement role of PE pipe materials will be more significant.
