1. Light quality, convenient transportation, loading and unloading, and small relative density.
2. It has excellent physical and chemical properties, high corrosion resistance, high impact strength, excellent acid resistance, alkali resistance, corrosion resistance and aging resistance. It is quite suitable for the main use of chemical industry, with a long service life of no less than 50 years. It is an ideal material for building water supply and drainage.
3. The fluid resistance is small, the inner cavity of the pipe is smooth, the roughness index is only 0.009, and the fluid resistance is small. The hydraulic standard of the pipe network is reasonably improved, and the system operation cost is reduced.
4. High mechanical strength, excellent impact resistance, impact resistance and tensile strength.
5. The construction of the project is simple and easy to install. The construction of the pipeline connection project is fast and easy, effectively speeding up the project progress, and the construction cost is cheap.
6. The project cost is cheap, the price is cheap, the transportation and construction are convenient, and the service life is long. Therefore, the overall project cost is cheap and the construction cost is saved. Compared with the cast iron pipes of the same specification, the construction cost can be greatly reduced.
7. It does not harm the water quality. The dissolution test confirms that it does not harm the water quality, and it is suitable for large-scale application and promotion.
