Advantage analysis of ductile iron pipe in use

Properties of ductile iron pipe and PVC plastic pipe: compared with ductile iron pipe,PVC pipe wall smooth characteristics, light weight, good corrosion resistance, pollution prevention performance, low price, but shortcomings, mainly have the following points:

(1) easy aging, heat expansion and cold contraction, should not be exposed to the sun for a long time, storage room temperature should not be greater than 40℃.

(2) low strength, poor compressive performance, improper construction is easy to cause deformation.

(3) poor rigidity, but the difference of deflection, easy to cause leakage.
