A Spiral Double Bolt Clamp is a specialized hose clamp designed to secure hoses with a spiral-reinforced outer surface, such as suction hoses used in irrigation or industrial applications. It differs from a standard Double Bolt Clamp in its unique design, which accommodates the ridges of spiral-reinforced hoses for a more secure and leak-proof fit.
Key Features of a Spiral Double Bolt Clamp:
- Spiral-Specific Design:
- The inner band of the clamp is contoured to match the spiral ridges of reinforced hoses.
- Ensures an even seal around the hose, preventing leaks or slippage.
- Double Bolt Mechanism:
- Features two bolts that allow for even tightening across the clamp.
- Provides a stronger grip and more consistent compression compared to single-bolt clamps.
- Heavy-Duty Construction:
- Typically made from galvanized steel or stainless steel for durability and corrosion resistance.
- Suitable for outdoor and wet environments commonly encountered in irrigation or industrial use.
- Wide Clamping Range:
- Accommodates various hose sizes and spiral patterns for versatile application.
Differences from a Standard Double Bolt Clamp:
| Feature |
Spiral Double Bolt Clamp |
Standard Double Bolt Clamp |
| Application |
Designed for spiral-reinforced hoses. |
Used for smooth or non-spiraled hoses. |
| Band Profile |
Contoured to match spiral ridges. |
Flat band for uniform compression on smooth hoses. |
| Seal Quality |
Prevents leaks by conforming to hose ridges. |
Effective for flat or even hose surfaces only. |
| Hose Compatibility |
Spiral-reinforced hoses (e.g., suction hoses). |
Smooth hoses, such as layflat or standard PVC hoses. |
Common Applications:
- Agricultural Irrigation:
- Secures suction or delivery hoses used in pumping stations and mainline water transfer.
- Industrial Use:
- Holds hoses in place for high-pressure or heavy-duty fluid transfer systems.
- Drainage and Dewatering:
- Used in systems requiring robust hose connections to manage high-flow or debris-laden water.
Benefits of a Spiral Double Bolt Clamp:
- Secure Fit:
- Prevents the clamp from slipping off spiral ridges, ensuring a reliable connection.
- Enhanced Seal:
- Provides a tighter, leak-proof seal by conforming to the hose’s outer surface.
- Durability:
- Withstands high-pressure, vibration, and harsh environments without loosening.
- Ease of Adjustment:
- The double-bolt system allows for precise tightening and adjustments.
How It Works:
- Place the spiral double bolt clamp over the hose, aligning it with the spiral ridges.
- Tighten the bolts evenly to compress the clamp onto the hose and fitting.
- Check for a secure seal and adjust as necessary to ensure a leak-proof connection.
In summary, a Spiral Double Bolt Clamp is specifically designed for securing spiral-reinforced hoses, providing a more tailored and reliable seal than a standard double bolt clamp. Its application in high-pressure and heavy-duty environments makes it a vital component in irrigation, industrial, and drainage systems.
