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 function of ductile iron manhole covers is to install them on urban roads, and they are mostly driven by cars every day. Therefore, the wear resistance requirements for ductile iron manhole covers are relatively high, otherwise the manhole covers are very easy to damage. So how should we install ductile iron manhole covers on urban roads? First, we need to check whether the reserved manhole cover installation holes on urban roads are square or circular. Under normal circumstances, it is circular because manhole covers made of circular shapes are not easily tilted or damaged under stress. In order to ensure the normal use of cast iron manhole covers, it is necessary to pay attention to the installation quality and measure the dimensions of the manhole covers that need to be installed. Before installing the manhole cover, it is necessary to check if there are any quality issues with the manhole cover itself. If the quality is not up to standard, it cannot be installed and used normally, after all, the quality requirements for manhole covers are relatively high in urban roads.
