What is a Flange?


A flange is a flat, circular, or ring-like device with evenly spaced holes for bolts, used to join or connect two pipes, valves, pumps, or other equipment. The primary purpose of flanges is to provide a secure connection that allows for easy assembly and disassembly while maintaining a leak-free seal in piping systems. Flanges are available in an extensive range of materials, sizes, and types, making them versatile for various applications.


Types of Flanges 


At Hilton Forge India, we understand the importance of providing a diverse range of flange options to meet the unique needs of our customers. Here are the types of flanges we offer:


  • Blind Flanges: These are solid disks used to close the end of a pipe, valve, or equipment. They are commonly used to cap off the ends of piping systems, allowing for easy access when necessary.


  • Lap Joint Flanges: Lap joint flanges are designed to slide over the pipe and are not welded to it. They are often used in systems requiring frequent assembly and disassembly.


  • Long Weld Neck Flanges: These flanges have an extended neck that provides additional support and reinforcement to the pipe. They are suitable for high-pressure and high-temperature applications.


  • Orifice Flanges: Orifice flanges are specifically designed for flow measurement and control applications, with an orifice plate installed between two flanges.


  • Slip-on Flanges: These flanges have a low hub that slips over the pipe, making them easy to install. They are ideal for low-pressure applications.


  • Socket Weld Flanges: Socket weld flanges have a recessed area where the pipe sits, providing additional support and stability. They are commonly used in high-pressure systems.


  • Spectacle Blind Flanges: These unique flanges have a solid circle and a ring, allowing for the temporary or permanent isolation of a pipeline. They are often used in pipelines with pigging systems.


  • Threaded Flanges: Threaded flanges have internal threads that allow for easy connection to pipes with external threads. They are commonly used in low-pressure, non-critical applications.


  • Weld Neck Flanges: Weld neck flanges are designed for high-pressure applications and provide excellent support to the pipe. They have a long neck that reduces stress at the base of the flange.


  • Face Type Flanges: We offers various face types, including flat face, raised face, and ring joint face flanges, to ensure a perfect fit for your project requirements.
