Ductile iron pipes are primarily used in building drainage systems. Their main functions are drainage and exhaust. During this process, there can be potential hazards if not paid attention to, so it is crucial to strictly adhere to the standards. Do you know the precautions to take when placing them? After the trench excavation for the track maintenance work, the pre-fabricated ductile iron pipe sections are sequentially arranged from the outlet towards the indoor direction. Gradually place the pre-fabricated sections into the operation pit, serving as the ash outlet, then seal off the main outlet, perform temporary support, and connect the sections according to the construction drawings.

Before drilling gray holes within the trench, the ductile iron pipes should be straightened, and the gaps at the socket and spigot connections should be evenly found using a helical drill or a fine helical chisel. The helical connections should then be compacted, straightened, and aligned. The soil on both sides of the pipeline should be well-supported to prevent displacement during gray hole laying. Prohibited items that corrode steel should not be stored near the accumulation area, and the top should be elevated, reinforced, and leveled to prevent moisture or deformation of the materials. Similar materials should be stacked separately according to the order of entry for ease of implementation of the Constitution. Open-air accumulation of steel sections should have wooden blocks or stones underneath, with a slightly inclined surface for drainage, and attention should be given to the straightness of the materials to prevent bending. These are some suggestions from our pipeline manufacturing company. I hope you can use them in the days to come. Our products, with T-type, N1-type, and S-type product interfaces, are available for users to select independently; anti-corrosion measures include external zinc spraying, non-toxic coatings, and cement lining, with wide application in water supply and gas supply industries.
