Summary of construction experience of ductile iron pipe fittings

No matter which industry you are in, over time, you will always accumulate some relevant experience in these industries. The same is true for the construction of ductile iron pipe fittings. The staff have been working in this post for a long time and have an understanding of its construction requirements and precautions. Let's take a look at the summary of their construction experience, which is as follows:

Construction of ductile iron pipe fittings

1. If the construction is in summer, vegetable oil should be used as the lubricating oil, and the joints can be covered with soil. If it is a cold winter, the rubber ring can be preheated with hot water. The purpose of this is to reduce the hardness to ensure rapid installation.

2. Before installation, the rubber ring can be soaked with water to better complete the installation work.

3. If you need to borrow the pipe during installation, if the rotation angle of the pipe itself cannot be satisfied, you can borrow the rotation angle according to the required angle. After calculation, cut the pipe socket and oblique the opening, which can increase the borrow rotation. Angle, and can ensure safe use.

4. If there is no condition to test the pressure with water, you can also consider using air to test the pressure.

5. Three links and elbows must be made of concrete buttresses. The trench backfill should be compacted in layers. If the pipeline crosses the road, in order to avoid crushing the pipe body, coarse sand can be backfilled to the top of the pipe.

6. In order to avoid the phenomenon of interface dripping during construction. During installation, the construction should be carried out in strict accordance with the specifications, and each pipe should be installed in place. For large-diameter pipes, the condition of each joint apron should be checked.

In fact, there are many points that need to be paid attention to during construction. Here is a brief introduction to some frequently encountered problems that need to be paid attention to during construction. The above information is a summary of the construction experience of ductile iron pipe fittings. I hope it will be helpful to you during your operation!
