Compared with ductile iron pipe, PVC pipe is characterized by smooth inner wall, light weight, corrosion resistance, good anti-scaling performance, low price, but the disadvantages are more, the main points are as follows:
(1) Easy to aging, thermal expansion and contraction, should not be long-term exposure to sunlight, should not be stored at room temperature greater than 40 ℃.
(2) Low strength, poor compressive strength, improper construction can easily lead to deformation.
(3) Poor rigidity, poor flexibility, easy to cause leakage.
The main components of ductile iron pipe are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Implementation of the standards GB / T13295-2003 ISO2531 / 2003, excellent corrosion resistance, good ductility, good sealing effect, easy installation, mainly for municipal, industrial and mining enterprises water, gas, oil and so on.
