Casting Stainless Steel Flange

Cast stainless steel flanges are manufactured using precision casting or resin sand casting processes to achieve reliable sealing connections between pipes, valves, pumps, and pressure equipment.

They are widely used in the oil and gas, chemical, marine engineering, water treatment, power, food, pharmaceutical, and shipbuilding industries, and are particularly suitable for large-diameter, complex structures, and cost-optimized projects.

Corrosion Resistance: Utilizing CF8, CF8M, CF3, CF3M, and duplex stainless steel, these flanges meet the corrosion resistance requirements of seawater, chlorinated media, and chemical environments, extending equipment lifespan.

Suitable for Complex Structure Manufacturing: Casting processes enable near-net-shape forming of irregular structures, large-size flanges, and specially reinforced designs, reducing machining and improving material utilization.

More Economical for Medium and Large Sizes: Compared to forged flanges, cast flanges typically offer better cost advantages for sizes above DN300 (12"), making them suitable for budget-optimized projects.

Stable and Reliable Sealing Performance: RF, FF, RTJ, MFM, and TG sealing surfaces are CNC machined, ensuring long-term stable sealing connections.
