Flanges
Riyaarth Overseas is a globally recognized manufacturer and exporter of premium flanges that adhere to ASME/ANSI/DIN standards. Our extensive range of flanges, including carbon steel, stainless steel, alloy steel, and special alloys, are designed to meet the demands of various industries, including oil and gas, petrochemicals, power generation, and more. We are committed to delivering superior-quality products that meet international standards and provide exceptional performance in the most demanding environments.
Flanges are essential components in piping systems, used to connect pipes, valves, pumps, and other equipment to form a reliable and leak-proof assembly. They allow easy access for cleaning, inspection, or modification of the system.
Types of Flanges We Offer:
- Weld Neck Flanges: Ideal for high-pressure applications, they are welded to the pipe and reinforce the piping system.
- Slip-On Flanges: Designed to slip over the pipe and are typically used in low-pressure applications due to their ease of installation.
- Socket Weld Flanges: Used in small-diameter, high-pressure systems, these flanges offer a strong, leak-proof connection.
- Lap Joint Flanges: Used with a stub end, they allow easy removal and rotation, ideal for systems requiring regular maintenance.
- Threaded Flanges: Provide a quick connection for low-pressure piping systems without the need for welding.
- Blind Flanges: Used to close the end of a piping system or vessel, providing easy access for future extension or maintenance.
- Reducing Flanges: Used to connect pipes of different diameters, ensuring a smooth transition and reducing turbulence.
- Spectacle Blind Flanges: Used to isolate or open a piping system, commonly employed in maintenance procedures.
Advantages of Using Flanges:
- Ease of Access: Flanges allow easy inspection, cleaning, and modification of piping systems.
- High Strength and Durability: Manufactured from high-quality materials, our flanges offer exceptional strength and resistance to corrosion, pressure, and temperature.
- Versatility: Suitable for a variety of piping applications, including high-pressure and high-temperature systems.
- Leak-Proof Connections: Ensure a tight seal between pipes and components, reducing the risk of leaks.

Flange Face Types
- Flat Face (FF): Used in systems where the mating flange or valve has a flat face.
- Raised Face (RF): Provides a better seal for systems under moderate to high pressure.
- Ring Type Joint (RTJ): Used in high-pressure applications, providing a strong metal-to-metal seal.
Surface Treatment and Coating
- Anti-Rust Coatings: To prevent corrosion and extend the service life of the flanges.
- Galvanization: Cold and hot dip galvanization for superior protection in harsh environments.
- Zinc Plating, Oil Black Paint, Yellow Transparent: Additional coatings for enhanced resistance and appearance.
