Cast Flanges
Cast Flanges are manufactured using advanced casting processes to provide durable and cost-effective piping connections for various industrial applications. These flanges are designed to connect pipes, valves, pumps, and other equipment while ensuring a secure and leak-proof seal. Their excellent strength, dimensional accuracy, and corrosion resistance make them suitable for low to medium-pressure piping systems.
At Royal Steel India, we manufacture and supply premium-quality Cast Flanges in a wide range of sizes, materials, and international standards. Our flanges are carefully engineered and quality-tested to deliver reliable performance, long service life, and excellent value across diverse industries.

Cast Flanges are pipe flanges produced by pouring molten metal into specially designed molds to achieve the required shape and dimensions. After casting, the flanges undergo machining and quality inspection to ensure accurate dimensions, smooth sealing surfaces, and dependable performance.
Cast Flanges are available in different configurations, including Slip-On, Blind, Threaded, Plate, and Custom Flanges, depending on the application requirements.
