What are the advantages and disadvantages of PPR plastic pipe compared with steel pipe?

Advantages and disadvantages are as follows:

1, light weight: the weight per unit length is only1/6 of that of cast iron pipes;

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

3. Low resistance: the inner wall of the pipeline is smooth and does not scale. The head loss of pipeline with the same diameter is lower than that of cast iron pipe by more than 30%, which can save a lot of operation.

Electricity bill;

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

5, convenient installation: flexible connection, rubber ring sealing, convenient installation, good sealing;

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

7. Non-toxic and hygienic: it meets the drinking water standard, and the delivered water has no secondary pollution;

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