Ductile iron manhole cover has better toughness, its impact is more than 10 times that of gray iron material, and ductile iron manhole cover has been widely used in the main factors of main roads, its strength is relatively high, it can be the same as low carbon steel, it is three times of gray iron material, iron price, steel quality.
In life, there are always some people who steal the well cover on the road to sell。 Classification standard of nodular cast iron manhole cover, because steel and other materials can be recycled and sold, and the quality of steel materials is very heavy。 For recycled materials, people have to convert the price according to the weight of weighing。 Therefore, the first work to be done for urban road well covers is to prevent theft。 Let's think about it。 If the well covers of our city's roads are stolen and taken away, will there be big holes one by one on the roads? It's very unsafe for pedestrians to travel。 It's very easy to fall down if you're not careful。
Nodular cast iron manhole covers have not been found, because all manhole covers are processed by lathe to solve the noise caused by wheel rolling. Secondly, the nodular cast iron manhole cover and well ring are almost worn-out, and the design is reasonable, which ensures that the fast-moving vehicles will not overturn and shift after they pass the warning. Moreover, the unique advantages of the ductile iron manhole cover are relatively long, which can be used for more than 30 years under normal conditions. In addition, the design of the product is reasonable, and the installation and opening are relatively convenient It is very convenient for the inspection and maintenance of underground pipeline facilities. It has light weight, large bearing weight, clear wrinkles and superior anti-skid performance.
The above is about the powerful function of ductile well cover. If you want to know more, please continue to pay attention to our Official website.
