With the development of the times, all kinds of manhole covers have emerged at the historic moment, so when we are driving on the road, we do not know if we have found that the manhole covers on the road are generally round ductile iron manhole covers or ductile iron Cover, then do you know why you like to use ductile iron manhole covers or covers on the road? What are the advantages of nodular cast iron?
Now, ductile iron manhole covers are widely used in road sewer mouths. Ductile iron manhole covers are solid, stable, and durable. They can play a vital role in the daily maintenance of roads, sewers, and optical fiber outlets in use. Moreover, his materials are low in price, widely used in the market, and adapted to market demand.
In fact, the reason why people like to use round ductile iron manhole covers is that ductile iron manhole covers have good flexibility. They are easy to make, whether they are square or round, and they are light in weight. They can also be saved in transportation and installation. A lot of costs. Therefore, on the whole, cast iron manhole covers have many advantages in design, cost, maintenance, and price.
For cast iron manhole covers are essential in road administration. The cast iron manhole covers we often see should be round and square manhole covers. Secondly, the reason why people like to use round ball-milled cast iron manhole covers is because round manhole covers are not easy to tilt and can Better protect the safety of pedestrians and vehicles. However, if a square is adopted, because the diagonal of the square is obviously longer than the length of each side, when such a manhole cover is rolled up, it is easy to fall into the well along the diagonal direction of the wellhead, causing hidden safety hazards.
So, do you know why ductile iron cover plates are installed in these places?
1. Ductile iron cover plate has good safety and protection effect. No need to worry about safety when pedestrians and vehicles walk on it.
2. Secondly, the product also has great load-bearing capacity. The tensile strength and toughness of the ductile iron cover plate are four times that of ordinary cast iron, which is close to that of steel, which is suitable for various roads.
3. Ductile iron cover plate adopts integrated connection during production, will not be separated from the ground and will not shift.
4. When in use, the ductile iron cover plate is integrated with the well seat, which has a very good anti-theft function, and it will not affect the appearance during use.
5. The ductile iron cover plate has a relatively strong corrosion resistance. As everyone knows, the environment in the sewage well is complicated, and various chemical substances are flooded. It is not corroded by chemical substances and has a service life of more than 30 years.
The above is the analysis of nodular cast iron manhole covers and nodular cast iron cover plates. Now everyone understands why nodular cast iron manhole covers are laid on the road? I hope that each of my articles can help everyone. You just need it, and I just happen to be professional. If you encounter any problems when choosing or using it, please feel free to call our phone and look forward to working with you.
