1. Light weight, convenient handling: low density, convenient handling, handling and construction.
2、耐腐蚀性优良：具有优异的耐酸、耐碱、耐腐蚀性，对于化学工业之用途甚为适合。
2. Excellent corrosion resistance: it has excellent acid resistance, alkali resistance and corrosion resistance. It is very suitable for chemical industry.
3、流体阻力小：管材内壁光滑，其粗糙系数仅为0.009，流体阻力小，有效地改善了管网的水力条件，减少了系统运行费用。
3. Small fluid resistance: the inner wall of the pipe is smooth, its roughness coefficient is only 0.009, and the fluid resistance is small, which effectively improves the hydraulic conditions of the pipe network and reduces the operation cost of the system.
4、机械强度大：管材具有良好的耐压性能，抗冲击性能和抗拉伸强度性能。
4. High mechanical strength: the pipe has good pressure resistance, impact resistance and tensile strength.
5、施工简易：管道连接施工迅速容易，施工工程费低廉。
5. Simple construction: the pipeline connection construction is fast and easy, and the construction cost is low.
6、造价低廉：价格低，而且运输、施工方便，使用寿命长，因此总体造价低廉。
6. Low cost: low price, convenient transportation and construction, long service life, so the overall cost is low.
7、不影响水质：由溶解试验证实不影响水质，适宜大面积推广应用。
7. No effect on water quality: it is confirmed by dissolution test that it does not affect water quality and is suitable for wide application.
