Flange x Thread (Van Stone Style)

n irrigation systems, a Flange x Thread (Van Stone Style) fitting is used to connect pipes or components with a flange on one end and a threaded connection on the other. The Van Stone style refers to a specific type of flange connection where the flange is loose and rotates around the pipe, allowing for easier alignment during installation.

Key Features:

1. Loose Flange Design:
   • The flange is not fixed to the pipe, making it easier to align bolt holes with a mating flange or equipment.
2. Threaded Connection:
   • The threaded end provides a secure connection to pipes, valves, or fittings with matching threads.
3. Material Options:
   • Commonly made from materials like PVC, stainless steel, or galvanized steel, depending on the application and environmental conditions.
4. Size Compatibility:
   • Available in various sizes to fit standard irrigation pipes and components.

Applications:

1. Irrigation Mainlines:
   • Connects mainline pipes to pumps, valves, or other fittings where alignment flexibility is needed.
2. Valve Installation:
   • Used to attach valves to pipelines, ensuring a leak-proof connection.
3. Pump Connections:
   • Facilitates connections between pumps and pipelines, allowing for easy alignment and maintenance.
4. System Maintenance:
   • Ideal for setups that require frequent disassembly or realignment, such as seasonal irrigation systems.

Benefits:

1. Ease of Installation:
   • The rotating flange allows for precise alignment during assembly, even in tight spaces.
2. Flexibility:
   • Suitable for a wide range of irrigation setups, including agricultural, industrial, and residential systems.
3. Leak Prevention:
   • Ensures a secure, watertight seal between connected components.
4. Durability:
   • Resistant to wear, corrosion, and environmental conditions, depending on the material used.

Considerations:

1. Proper Alignment:
   • Ensure the threaded end is securely connected and the flange is correctly aligned for a proper seal.
2. Pressure Rating:
   • Verify that the fitting’s pressure rating matches the irrigation system’s requirements.
3. Maintenance:
   • Periodically inspect the fitting for signs of wear or corrosion, especially in high-pressure or chemically intensive environments.
