Comparison between ductile iron pipe and PVC plastic pipe

Performance comparison between ductile iron pipe and PVC plastic pipe:

Compared with ductile iron pipe, PVC pipe is characterized by smooth inner wall, light weight, good anti scaling performance, etc., but it also has many disadvantages, mainly including the following:

(1) It is easy to age, expand with heat and shrink with cold, and should not be exposed to sunlight for a long time. The room temperature should not be higher than 40 ℃.

(2) Low strength, poor compression resistance, and deformation is easily caused by improper construction.

(3) Poor rigidity, poor flexibility, easy to cause leakage.
