Manhole covers are used in many places, and they are used in different applications. The types of manhole covers required are also different, especially the requirements for materials are very different. Next, the editor will tell you what are the classifications of manhole covers, and what specific occasions are they used in?
For some living areas such as residential quarters, streets and alleys, because most of the time only light motor vehicles and small cars pass through, the use of ordinary cast iron manhole covers can fully meet the requirements of use. After all, the bearing capacity of manhole covers in this environment There are no too strict requirements.
However, for areas such as main roads, highways, and expressways in cities, the requirements for the material of manhole covers are relatively higher. In order to meet the requirements of these areas, only ductile iron manhole covers are competent.
In addition, there are green belts, sidewalks and other areas where motor vehicles are prohibited from entering. Here, composite manhole covers are mostly used, because they not only have the practical use of ordinary manhole covers, but also can beautify the environment to a certain extent. It can be seen from this that the selected manhole cover material is very important and must be selected according to the characteristics of the actual occasion.
Ductile iron manhole cover is a product used on highways. If its quality is not good, it will become a safety hazard in our lives. The quality of the product includes several aspects, including the appearance quality, internal quality and use quality of the product. Any factor may affect the overall quality, so each aspect cannot be ignored. The shape and size of the product are all verified by design. The raw materials for the production of this product are carefully selected, and its manufacturing process is determined through experiments. Every link is very important.
