Round anti-settling ductile cast iron rain manhole cover
Round anti-settling ductile cast iron rain manhole cover, introduced as follows: 1. Material: The use of ductile cast iron, it is through the spheroidization and inoculation treatment to get spherical graphite, and then the mechanical properties of cast iron improve and improve a lot, ductile iron manhole cover is one of the products of ductile iron. 2. Features: strong pressure resistance, uniform force, acid and alkali corrosion resistance, long service life, not easy to sink. 3. Load: the load is 400KN, equivalent to about 40 tons of load. 4. Size :700m*1000m, that is, the diameter of the inner manhole cover is 700m, and the diameter of the outer frame is 1000m. In addition, our company supports customization, you can customize different sizes and patterns of circular anti-settling ductile cast iron manhole covers.
