Description:
Premium Double Bolt Clamps for High-Pressure Hose Assemblies RockClamp's double bolt clamps are designed for the most demanding industrial applications, providing superior gripping power for heavy-duty suction and discharge hoses. Manufactured from high-strength malleable iron or stainless steel, these clamps feature dual bolts for even tension distribution and an interlocking design to prevent hose blow-outs.
Our double bolt hose clamps are widely used in mining, construction, and oil & gas industries due to their exceptional durability and ease of installation. With a wide range of sizes available, they ensure a leak-proof seal on thick-walled hoses. All products undergo rigorous testing to meet international safety standards.
Material:
W1 - All parts carbon steel with yellow zinc plate
Surface electro-galvanized (zinc yellow) provide basic rust protection through zinc coating. The zinc plating offers cost efficiency with moderate corrosion resistance. It retains the base iron material's mechanical strength, ideal for cost-sensitive, low-to-medium corrosion applications like indoor plumbing or agricultural machinery parts.
Features:
Compared to single bolt clamps, double bolt clamps offer the following advantages:
- More balanced and stable clamping force distribution
- Reduced risk of loosening under vibration or dynamic loads
- Higher overall clamping strength and load capacity
- Better resistance to torque and rotational forces
- More uniform pressure distribution across the clamped surface
- Increased reliability for critical applications
- Improved durability and longer service life
- Greater adaptability to varying material thicknesses
