The Hainan nodular cast iron manhole cover has various shapes, high density and high polymerization degree, so it has the advantages of wear resistance, corrosion resistance, environmental protection, etc. It is a relatively green product. However, if the production and installation are not strictly in accordance with the standards or do not know anything about its precautions, No matter how good the product is, it will not produce the best effect. Now let's learn about its installation?

1. The load capacity of nodular cast iron manhole cover after installation shall not exceed the specified load capacity of the product.

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