Our Alloy Steel Flanges are known for their exceptional durability, superior corrosion resistance, and outstanding performance in high-temperature environments. Available in various grades, our flanges are manufactured to meet international standards, ensuring that they serve the most demanding applications with utmost reliability.
Types of Alloy Steel Flanges We Offer
We manufacture and supply a wide variety of Alloy Steel Flanges, including:- Slip-on Flanges: Slip-on flanges are one of the most commonly used flanges in piping systems. They are easy to install and provide a reliable connection between pipes. These flanges are available in a range of sizes and materials, making them versatile for various industrial applications.
- Weld Neck Flanges: Weld neck flanges are designed for high-pressure and high-temperature applications. Their tapered neck provides strength and can handle the stress and pressure in critical environments. Our Weld Neck Flanges are made with approximately 24% chromium, offering resistance to scaling at temperatures up to 1100°C.
- Blind Flanges: Blind flanges are used to seal the ends of piping systems and prevent the passage of fluids or gases. Our Blind Flanges are designed to withstand environmental factors such as wind exposure, industrial pollution, and elevated temperatures, making them ideal for coastal and marine applications where corrosion is more prominent.
- Socket Weld Flanges: Socket weld flanges are suitable for small-diameter piping systems. The socket-type design ensures a smooth connection and reduces the risk of leakage, making them perfect for high-pressure applications in various industries.
- Ring Joint Flanges: These flanges feature a metal-to-metal sealing surface, providing a leak-tight seal under high-pressure conditions. They are commonly used in industries such as oil & gas and petrochemicals.
- Threaded Flanges: Our threaded flanges are ideal for use in systems where welding is not feasible. They are designed with threads for easy installation and can be used in a wide range of applications.
