The Quality of manhole covers depends on nodularity. Ductile iron manhole cover India is mainly called ductile iron or nodular iron. The pouring process generally uses asphalt anti-corrosion paint. In other words, the surface of manhole covers made of ductile iron is generally sprayed with asphalt to prevent rust.

The advantages of nodular iron of BIC India over other metals are given below.

Unbreakable even when bent

Ductile cast iron, manufactured from materials such as silicon, phosphorus, magnesium, and sulfur, is used to reinforce the iron cover. This makes for a very durable material. Another highlight of ductile iron is that it bends easily without the risk of breakage.

Compressive strength

While talking about strength, you must consider the compressive strength of this metal. In other words, it is the pressure that a metal can withstand or resist changing its shape. It will be a substitute for Corrosion resistance

When manholes are exposed to the whims of nature such as hail, frost, rain, and sun, they are at high risk of damage.

Cost-effectiveness

The most important criterion in manhole manufacturing is cost-effectiveness. Ductile cast iron is popular in the manufacturing industry because it is inexpensive compared to other metals. This is an important factor most manufacturers consider, but there is no doubt that this metal outperforms others when it comes to performance.

Features of the Ductile Iron Manhole Cover are as follows.

High strength

The tensile strength of ductile cast iron exceeds 420 MPa. The yield point exceeds 300 MPa. Strength of ductile iron manhole cover India is equal to low-carbon steel and more than three times gray iron.

Good toughness

The impact value is comparable to carbon steel and 10 times higher than gray cast iron.

Good plasticity

The elongation rate is 7% or more, which is equivalent to high carbon steel and gray cast iron.

Corrosion resistance

In the 90-day spatter corrosion test performance of ductile cast iron, corrosion was only 0.25 times that of piping and 0.1 times that of gray cast iron piping. The service life is twice that of cast iron pipes and five times that of ordinary steel pipes.
