Product Description

What is Ring Forging? What applications are Steel Ring Forgings? 

Ring forgings are industrial products that apply external force and improve the physical properties of metals through the use of forging hammers or pressure, and are widely used in various industrial fields: petrochemical industry, mining equipment industry, nuclear power pressure shells and in-stack components, hydroelectric turbine shafts, marine main engines and shaft rudder system forgings, weapons, diesel engine forgings, etc. 

Petrochemical ring forgings: forgings have a wide range of applications in petrochemical equipment. Such as spherical storage tank manhole, flange, heat exchanger required for a variety of pipe plate, butt welding flange catalytic cracking reactor forging cylinder (pressure vessel), hydrogenation reactor used in the cylinder section, fertilizer equipment required for the top cover, bottom cover, head, etc. are forgings.

Mining ring forgings: the proportion of forgings in mining equipment is 12-24% by weight of the equipment. Mining equipment are: mining equipment, winding equipment, crushing equipment, grinding equipment, washing equipment, sintering equipment.
