Our application of ductile iron well covers has undergone continuous technological updates and practical applications, which have made a comprehensive change in our safety problems. The performance of cast iron well cover is the premise of our wide application. As we all know, iron products are very easy to rust, so good our Shandong Ductile Iron Well Cover anti-corrosion have those tricks, let's take a look at it.
It is well known that nodular cast iron well cover is an important installation in road and green road. The quality of nodular cast iron covers directly determines whether pedestrians will have accidents when they pass through here. If the quality of nodular cast iron covers is not good, it will inevitably lead to potential safety hazards in our daily travel.
Ductile iron well covers have to withstand such tests for their anti-corruption performance。 To achieve this effect, they need to be treated strictly。 They are coated with asphalt, pre-heated pipes before spraying paint to speed up the adhesion of asphalt and dry quickly, as well as aluminium-aluminate coating。 These two processes are very good。 With anti-corrosion coating, ball-milling well cover is a kind of cast iron, which is treated by cast iron and spheroidizing to nodular graphite shape, so that the performance of cast iron can be effectively improved, especially the plasticity and toughness of the product can be improved, and ultimately the strength of the product is higher than that of carbon steel。 This is the characteristics of our nodular well cover。 With these characteristics, we can certainly improve the performance of cast iron。 To withstand all kinds of severe tests。
