1. Light weight: the weight per unit length is cast iron pipe

2. High strength: tensile strength can reach more than 45Mpa;

3. Low resistance: the inner wall of the pipe is smooth and non-fouling. The head loss of the pipe of the same caliber is 30% or more lower than that of cast iron pipe, which can save a lot of operating power costs.;

4. Corrosion resistance: it has good acid, alkali, chemical resistance, and electrical corrosion resistance, and there will be no pitting corrosion in use.;

5. Easy to install: flexible connection, rubber ring sealing, easy installation and good sealing;

6. Long life span: under normal working conditions, the service life can reach 50 years;

7. Non-toxic and hygienic: it meets drinking water standards, and the delivered water is not subject to secondary pollution.;

8. Low cost: transportation and installation costs are low, material costs are cheap, and the total project cost is 30% lower than that of cast iron pipelines.
