Nowadays, people are demanding more and more carefulness in life, more and more perfect. A perfect nodular manhole cover is an essential material. Maybe most people don't know much about it. Let's see why it is essential material.
Ductile iron has relatively poor fluidity and large shrinkage, so it requires a higher pouring temperature and a larger size of the pouring system. The riser and cold iron are reasonably applied, and the sequential solidification principle is adopted. It has high safety and reliability. The manhole cover anti-theft device has been patented in China, the United States, and Japan, and the effect is very good. It is a kind that has light weight and high strength. Damaged safety, simple molding, noise-proof rubber strip elastic buffer layer in the center of the manhole cover and the manhole cover seat can separate them and cannot be touched directly. So as to achieve the effect of preventing noise.
