Adjustable nodular cast iron manhole covers are generally adjustable anti settlement nodular cast iron manhole covers. The difference in the stress load is that the whole derrick is not designed directly at the wellhead, but as a part of the road surface.

The mechanical properties of the nodular cast iron test piece are as follows: tensile strength: 500N/MM2; elongation: 7%; adjustable anti settling nodular cast iron manhole cover is low in price; it is precision cast from high-quality nodular cast iron raw materials. This product has five prevention functions, and d400 heavy nodular cast iron manhole cover has multiple functions such as shock absorption, anti-theft, anti displacement, anti-skid, and damage prevention.
