How to install ductile iron manhole covers
Cast iron products are used in many occasions in daily life. It should be noted that cast iron products not only have strong plasticity, but also have much higher toughness than normal carbon steel. It is precisely because of the high-quality performance of cast iron castings that manufacturers choose to process cast iron products into ductile iron manhole covers.
The History of Ductile Iron Well Covers
The underground of a major city is filled with underground utilities: sewers, rainwater channels, steam tunnels, and utility corridors. Usually, channels called manholes are regularly excavated into these underground pipelines for maintenance personnel to access them. A manhole cover is necessary so that people can clean, inspect, or repair underground utilities. In the third water supply tunnel in New York City, the manhole cover can be as shallow or as deep as 70 floors. The manhole cover is a circular iron plate that sinks into the streets and sidewalks, preventing pedestrians from falling into the manhole.
