Rishabh Industries offers premium weld neck flanges, designed to form a robust, integral connection with pipes.
We are based in Ahmedabad, Gujarat, India.
These flanges are ideal for high-stress applications such as ASME pressure vessels and are engineered to ensure durability, strength, and optimal fluid flow.
Materials Used
Weld neck flanges are manufactured using high-quality materials, including:
- Carbon Steel (with or without GI coating)
- Cast Iron
- Copper
- Aluminum
The internal diameter of each flange is designed to match pipe flow, reducing friction and enhancing efficiency.
Types of Weld Neck Flanges
1. Standard Weld Neck Flange
- Features a long conical neck welded to the pipe for maximum strength.
- Helps distribute stress evenly along the pipe, enhancing longevity and durability.
2. Reduced Weld Neck Flange
- Designed to connect pipes of different diameters.
- Not considered a separate type but allows for size transitions between larger and smaller pipes.
3. Long Weld Neck Flange
- An enlarged version of the standard weld neck flange.
- Commonly used in columns, barrels, and nozzles.
- Available in two main variations:
- LWN Heavy Barrel
- Equal LWN Barrel
4. NW Long Weld Neck Flange
- Ideal for vacuum systems due to its tapering long neck design.
- Made of high-quality stainless steel for durability and stiffness.
- Directly attached to vacuum chamber surfaces for an airtight system.
- Available in sizes ranging from NW10 to NW50.
Benefits of Weld Neck Flanges
- Leak Resistance: Ensures a tight seal between pipes for safe, leak-proof connections.
- Superior Strength: Withstands high pressure and temperature, offering superior structural integrity.
- Enhanced Durability: Resistant to corrosion, wear, and erosion, resulting in a longer lifespan.
- Reduced Stress Concentration: Distributes stress from the neck to the pipe base, minimizing cracks and failures.
- Low Maintenance: Durable design reduces the need for frequent inspections and repairs.
- Improved Flow Characteristics: Smooth bore reduces pressure drop and turbulence, enhancing fluid flow.
- Reliable & Strong: Thickened flange face ensures stress is evenly transferred along the pipe.
- Easy Alignment & Installation: Facilitates accurate alignment, simple installation, and easy weld integrity testing via radiography.
Applications of Weld Neck Flanges
Weld neck flanges are widely used in industrial piping systems due to their reliability and versatility:
- Connecting pipes and tubes securely.
- Linking valves and other piping components.
- Used in chemical plants, water and oil rigs, and high-pressure systems for stable connections.
