It is important that the manhole cover cast material has both aesthetic and sanitary value. In this case, knowledge of the strength of the material is required. Now let’s move on to ductile iron, which has many features when casting manhole covers. So what makes BIC India, ductile iron, superior to other metals when casting manhole covers?
Ductile iron manhole cover India is mainly made of ductile iron or called ductile iron or nodular iron. Good or bad quality depends on modularity. Anti-rust asphalt paint is commonly used in the pouring process. Surface treatment of ductile iron manhole covers is performed by spraying asphalt anti-corrosion paint.
Features of ductile cast iron manhole cover:
High Strength
The tensile strength of ductile cast iron is more than 420 MPa and the yield strength is more than 300 MPa, which is the same as low-carbon steel and three times that of gray cast iron.
Good Toughness
The impact value is similar to that of carbon steel and ten times higher than that of gray cast iron.
Good Plasticity
It has a ductile elongation of 7% or more, similar to carbon steel, gray cast iron material, and zero elongation.
Corrosion Resistance
Corrosion resistance was only 0.25 times that of the pipe during the 90-day spray corrosion test and 0.1 times that of the gray cast iron pipe. The service life is twice that of cast iron pipes and five times that of ordinary steel pipes.
For most municipal applications such as water, salt water, and steam, cast iron has higher corrosion and oxidation resistance than steel. Due to the microstructure of spheroidal graphite cast iron, ductile cast iron outperforms steel in terms of reduced vibration capacity, and we produce the best ductile iron manhole cover India.
Advantages of ductile cast iron manhole covers:
Low cost is a major reason why cast iron is much more acceptable than steel, and ductile iron is growing in popularity. Casting is more efficient and machining costs for ductile iron are lower. Ductile iron manhole covers have another advantage. Due to the high strength and toughness of ductile iron, a ductile iron manhole cover is about 30% lighter than the same type of manhole cover made of gray cast iron.
Ductile iron manhole covers are one of BIC India’s main products. There is no doubt that ductile iron manhole covers play an important role in your daily construction.
