Ductile iron is a kind of high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is precisely based on its excellent performance that it has been successfully used to cast some parts with complex stress and high requirements for strength, toughness and wear resistance. Ductile iron It has rapidly developed into a widely used cast iron material second only to gray cast iron. The so-called "replacing steel with iron" mainly refers to nodular cast iron.

3. When installing the grate, the bottom surface of the grate shall not be suspended. Refer to the installation method of well circle.

4. When placing the well circle and grate, - shall be placed when the concrete thickness at the bottom of the well circle and grate is not less than 30mm, and the well circle shall be compacted or knocked to make it closely combined with the concrete, so as to increase the contact area between the well circle and grate and the well platform.

5. The load capacity of the product after installation shall not exceed the specified load capacity of the product.

6. The sundries in the well circle shall be removed before capping to avoid the contact between the well cover and the well circle points.

7. Open with a tool.

8. When the manhole cover and rainwater grate are not installed, they must be placed square to prevent the rolling of vehicles.
