Heavy Ductile Iron Cover is a common industrial equipment, and its performance advantages and other materials, compared to the covers are also very significant, then what are the specific aspects of it, then we come here to give you a brief introduction.

First of all, this equipment is made of ball mill cast iron, and the quality of this well covers also involves the problem of spheroidization rate, under normal circumstances, the common casting castings is rust-proof asphalt paint, and ductile iron Well covers also have the advantages of high strength and toughness.

Second, this kind of covers are also very strong corrosion resistance, the service life is 2 times the gray iron pipe, 5 times the ordinary steel pipe.

In addition, the plasticity of the covers is also good, and high-carbon steel is almost, and because the spherical cast iron ball is a micro-structure, in reducing the vibration capacity, ductile iron is also higher than the cast steel, and therefore more conducive to reducing stress.
