How to Choose, Install and Maintain Ductile Iron Pipe
Firstly, let’s see why choose ductile iron pipe.
In building construction, especially the construction of urban water supply pipeline network, the pipeline products used require high strength, high toughness, strong corrosion resistance and comprehensive cost of construction and installation. From these perspectives, ductile iron pipe is undoubtedly the best choice. From the production process of ductile iron pipe to the final construction and installation, it meets our requirements. No matter how complicate the project, choosing ductile iron pipe as the main pipeline product is definitely a wise choice with the highest cost performance in the long term.
Secondly, the installation of ductile iron pipe mainly includes the following steps:
1. Site selection
Select the installation route of the ductile pipe from the perspective of soil quality and nearby pipelines, and form construction drawings. Special attention should be paid to avoid some corrosive and unsafe installation routes.
2. Pipe laying
Use Large-scale equipment such as excavators and hoisting machines in the pipe laying process. At the same time, a 10-meter ductile pipe should arrange 2 to 3 workers based on experience. The rubber ring should be placed in the socket groove and compacted by hand.
3. Determine the distance of the pipeline
The key of this step is to cut off the iron pipe if it’s too long. And process the spigot end into a groove shape according to the construction angle to facilitate application.
4. Tube body measurement
Through the measurement of the tube body, to demtermine the straight line space and the corner space formed by the installation radian, vacancy, and transfer. Thus in order to achieve stability and avoid displacement.
5. Positioning marking
The purpose of the positioning marking is to achieve that the fixed pipe and moving pipe axis lines are on the same straight line as a wheelbase. This step is to ensure the quality and speed of the installation. Also it helps to prevent the pipeline apron from falling off and affecting the quality and progress.
6. The installation of pipes should be flat, and the pipes should be in a straight line. Besides, be careful of inclination angle.
7. Align the interface of the connecting pipe with the socket. If the insertion resistance is too large, do not insert it forcibly to prevent the rubber ring from twisting.
8. When pipeline installation and laying works are interrupted, use its cap to close the pipe opening to prevent dirt, sand and other debris from entering the pipeline.
9. Cover the middle part of each pipe with soil before the pressure test.
Then, how to maintain ductile iron pipes? Let me introduce to you briefly.
The maintenance of the ductile tube should always start from its selection. Before the project starts, we should perform a visual inspection of the parts, such as pipe fittings, aprons, elbows, etc., so as to avoid using defective parts.
The second point of maintenance is to check and acceptance check. We should pay attention to the socket apron lower tube (pipe) that affects the long-term stable operation, and strive to have no debris in the socket in these aspects. The rubber ring has been hit by a rubber hammer without warping and twisting, and is evenly stuck in the groove.
During the maintenance process of ductile iron pipes, since the axis of the moving pipe is deeply buried in the ground, be careful when there is an inclination angle. If the resistance is too large, do not excavate forcibly to prevent the rubber ring from twisting. The maintenance of ductile tubes in winter also needs preheating with hot water to reduce the hardness and install quickly.
In addition, if the quality of the ductile iron pipes used in the project absolutely meets the national standards, then we should pay attention to the apron, welding, etc. AC and DC. As long as the ductile cast iron pipes are applied properly and the product quality is excellent, it can reduce unnecessary troubles in installation projects. Also, as a new type of pipe material, its future maintenance work is relatively easy.
