Ductile iron manhole covers originally have so many advantages. We may often see manhole covers, but do you know ductile iron manhole covers? It is a special new type of manhole cover. You can first listen to the editor to introduce its advantages.
1. Anti-theft of ductile iron manhole cover: put the anti-theft box under the well circle, open the manhole cover, the cover does not use anti-theft chain, but the anti-theft effect is better, and the rust problem is solved.
2. In order to prevent falling, there needs to be an anti-drop grille in the manhole cover. Injuries from falling people or other objects can be avoided if the manhole cover is not covered or is missing.
3. In order to prevent the displacement of the manhole cover of ductile iron, the well ring is fixed with anchor bolts, and the small round hole in the middle plays a role of fixing. After the manhole cover is built, the well ring will not cause false openings, and the rolling and car rolling are in line. construction standards.
4. In order to prevent noise and make the contact surface between the ductile iron dome and the well ring more consistent, it should be processed so that there will be no abnormal noise when the car returns through the well cover.
5. Ductile iron is non-slip, and the surface of the manhole cover must have a diamond pattern to prevent sliding. Use requires ring-to-ring connection structures. At the same time, it is necessary to increase the wear resistance coefficient of the ring surface, increase the T-shaped protrusion, and increase the wear resistance coefficient of the asphalt base material and the ring mouth.
The scope of application of ductile iron manhole covers is very wide, and its advantages make more and more people tend to choose it. The reason why there are so many advantages is that the raw materials used to make it are good.
