What is the Difference Between Polyethylene Pipe and Ductile Iron Pipe?

As a Ductile Iron Pipe Suppliers, share with you. The resistance coefficient of the pipe network is small and does not scale. Under long-term use, it saves a large amount of operating energy and has certain economic benefits; the PE pipe construction device is convenient, sensitive, efficient, and diverse in connection methods, suitable for various projects. Under the condition of shallow burial depth, PE pipe is better than ductile iron pipe in safety when receiving dynamic load.

Ductile Iron Pipe

Since ductile iron pipes are rigid pipes, when there is an additional load in the air, most of the force acts on the pipe. When the pipe undergoes repeated deformation or the partial pipe section gradually sinks, the tightness of the flexible joint will be affected. There is a hidden danger of leakage. PE pipes are flexible pipes. When there is a dynamic load in the air, the force acts on the pipes.

The pipe undergoes flexible deformation, and the soil around the pipe generates a passive force, which causes the air load to spread to the surrounding soil, which greatly reduces the force on the pipe. In addition, since the joint strength of hot-melt welding is much greater than that of the pipe itself, the effect of dynamic load will not affect the safety of the joint. Therefore, under the condition of very shallow burial, PE pipe has higher safety.

In terms of short-term investment, the material cost of PE pipes and fittings is lower than that of ductile iron pipes; PE pipes are light in weight, which reduces the labor intensity of construction personnel, saves hoisting machinery, improves construction efficiency, and reduces construction costs. In addition, the PE pipe is flexible and can change with the terrain, and can stop welding on the ditch. There are special welding machines for welding, which not only improves the construction speed, but also greatly reduces the amount of earthwork for the ditch. In addition, the polyethylene piping system does not need to stop expensive anchoring.
