Stainless steel flanges are essential components in pipeline systems, pressure vessels, and machinery connections due to their excellent corrosion resistance, strength, and durability. Among various manufacturing methods, the ring rolling forging process has become the preferred choice for producing high-quality stainless steel flanges.
What is Ring Rolling Forging?
Ring rolling is a special forging process used to produce seamless rolled rings with superior mechanical properties. In this process, a pre-formed ring blank is heated and placed between two rollers. The inner roller applies pressure, reducing the wall thickness and increasing the diameter, while the outer roller provides support, creating a precise and strong forged ring.
Advantages of Ring Rolling for Stainless Steel Flanges
Enhanced Mechanical Properties
The forging and deformation during ring rolling refine the grain structure, improving tensile strength, impact toughness, and fatigue resistance of stainless steel flanges.
Improved Material Utilization
Compared with machining from a solid billet, ring rolling reduces material waste significantly, resulting in lower production costs for customers.
Seamless Structure
Ring rolled flanges are free from internal defects common in welded flanges, ensuring reliable sealing performance in high-pressure applications.
Flexible Size Range
Ring rolling can produce flanges with diameters from 200mm up to 6000mm , meeting various industrial requirements.
