The manhole cover is usually used to cover the road surface cover the deep well at home. The key function is to prevent people objects falling. Nowadays, most of the manhole covers sold on the market are ordinary manhole covers. With the improvement of safety awareness, ductile iron casting manhole covers have come into our view, have just received more more attention.

What are the differences between ductile cast manhole cover traditional manhole cover? Today, I'd like to take you to master the manhole cover of ductile iron casting

1. The application situation of ductile iron well cover: at present, the key to this kind of manhole cover is in the urban municipal engineering, roads, highways other areas. In this area, the quality requirements for the picosecond laser cutting manhole cover are quite strict, the excellent ductility compressive strength of ductile iron castings can be considered thoroughly. The general manhole cover is used in the non motor vehicle driving into the area, road greening, sidewalk other places.

2. Appearance of spheroidal graphite well cover: generally, it is made of engineering projects with basic principles of structural mechanics, with beautiful appearance, elegant exquisite appearance. The laser cutting of pipes adopts polymer materials to generate materials for precision production; by comparison, the surface of general manhole covers is smooth, the processing technology is smooth, it is easy to have cracks.
