The maintenance and care of ductile iron pipes should begin right from the selection stage. Before the project commences, we should conduct a visual inspection of the required components, such as pipe sections, O-rings, elbows, etc., to avoid using defective parts.

The second focus of maintenance is on the acceptance of working hours. We should pay close attention to the gaskets and fittings of the pipeline (drip pipes) that affect long-term stable operation, striving to ensure that there is no debris in these areas. The gaskets have been securely seated with a rubber mallet, without any warping or twisting, and are evenly clamped into the groove.

During the maintenance and care of ductile iron pipes, since the moving pipe axis line is deeply buried underground, caution is required when encountering an angle of inclination. If excessive resistance is encountered, do not force excavation to prevent the rubber ring from being distorted.

Ductile iron pipes require preheating with hot water during winter maintenance to reduce hardness and facilitate quick installation.

Additionally, if the ductile iron pipes used in the project meet national quality standards, we should pay attention to the dual AC/DC compatibility of gaskets and welds.
