Nodular cast iron manhole covers have been widely used in almost all major industrial departments, and these departments need to meet the service conditions of strength, plasticity, toughness, wear resistance and dimensional stability. In order to meet the use of these conditions, we provide you with a wide range of mechanical properties and kissing properties. In order to meet these special uses, our company has developed a group of Austrian ductile iron, which is mainly alloyed with zinc, chromium and manganese and listed in international standards. The elongation and strength of the product are not the basis for the designer to select materials, and its decisive importance also includes yield strength and elastic modulus. And wear resistance, fatigue strength, resistance and so on, while corrosion resistance and electromagnetic properties are important for designers
1. Anti noise: the contact surface between Xiangming cast iron well cover and well ring is machined to make it more consistent without abnormal noise.
2. Antiskid: diamond block pattern and plus sign pattern are cast on the surface of Xiangming cast iron manhole cover. The inspection well ring adopts the structure of connecting the ring with the ring, and a T-shaped protrusion to increase the wear resistance coefficient is set on the surface of the ring mouth, so as to increase the wear resistance coefficient between the asphalt base material and the ring mouth after the auxiliary road
The above is the detailed introduction of Shandong ductile iron manhole cover. I hope it will be helpful to you If you have any questions, please contact us We will provide you with professional service http://www.jnwszy.com
