Advantages and disadvantages of ductile iron pipe application

Advantage:

Compared with PE pipe,

In terms of installation time, ductile pipes are easier and faster to install than PE pipes, and the internal and external bearing pressure is better after installation;

From the perspective of airtightness and corrosion resistance, the airtightness of the ductile pipe is better after installation, and the corrosion resistance performance can also be improved through a variety of anti-corrosion methods;

From the perspective of hydraulic performance, the ductile ink tube specifications generally refer to the inner diameter, and the PE tube specifications generally refer to the outer diameter. Therefore, under the same specifications, the ductile ink tube can achieve greater runoff;

From the perspective of comprehensive installation and maintenance cost, the ductile tube has a more superior cost performance. The inner wall is sprayed with zinc, cement mortar, and anticorrosive materials.
Disadvantages:

In the high-pressure pipe network, it is generally not used, and the pressure resistance is low. Because the pipe body is relatively heavy, machinery must be used for installation. If there is water leakage after the pressure test, all the pipes must be dug out, the pipes should be hoisted to a height that can be put into the clamp, and the clamp should be installed to prevent leakage.
