What is the difference between steel mesh skeleton plastic composite pipe and ductile iron pipe

Jan 26, 2022

Steel mesh skeleton plastic composite pipe and ductile iron pipe are two common types of pipes, which are used by many people because of their wide range of uses. So, do you know the difference between steel mesh skeleton plastic composite pipe and ductile iron pipe?

Steel skeleton plastic composite pipe Ductile iron pipe The fixed length can be up to 12 meters (also can be customized longer), and the number of joints in the pipe network is small. The maximum fixed length is 6 meters, and the number of joints in the pipe network is large. It has good flexibility and can be laid in a serpentine shape with the undulating terrain, which can easily bypass obstacles and further reduce the number of joints.

The flexibility is poor, and the number of elbows and other accessories is required to meet complex terrain obstacles, which further increases the number of joints and has many potential safety hazards. Good corrosion resistance, no need for anti-corrosion treatment. Corrosion resistance is poor and requires anti-corrosion treatment. Good impact resistance, high elongation at break (>350%) Poor impact resistance, low elongation at break (>10%).

The pipeline adopts electrofusion connection, which is simple to connect and has good air tightness. The pipeline adopts socket-type connection, the connection is more complicated, the specific gravity is about 30% of the steel, the same volume and weight are lighter, the transportation and construction are easy, and the construction cost is low. The proportion is 6.9, the transportation and construction are difficult, and the construction cost is high.

The maintenance is simple and convenient, and the maintenance cost is low. It is not easy to repair (cannot be welded), and the maintenance cost is high. The service life can be up to 50 years.

The service life is about 15 years.

When the pipeline passes through some strata with low cutting force or unstable (subsidence caused by the extraction of groundwater, swamp, etc.), it has good deformation resistance with the movement of the stratum, and the pipeline joint is not easy to be damaged. When the pipeline passes through the aforementioned unstable formation, the joint of the pipeline is easily damaged when the formation moves. When the pipeline is in the earthquake fault zone and is subjected to impact force, the pipeline is not easy to be directly fractured and damaged. The pipeline is prone to fracture damage when it is impacted by the seismic zone.

The main form of pipeline damage is external force damage, and the overall safety is high. There are many forms of pipeline damage, and the overall safety is low. It has good hygienic performance and has passed various tests of the National Preventive Medicine Association and can deliver drinking water. Hygienic performance is poor.
