Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it is centered. 2. Place the provided flat or cushion washers (if applicable) over the threaded ends. 3. Thread the nuts onto the U-bolt. Tighten evenly and sequentially until the pipe is firmly secured, but avoid overtightening, which can deform the pipe or U-bolt.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting the wrong U-bolt size for the pipe diameter.Always verify the nominal pipe size and consult the U-bolt's inside dimensions (A and B) to ensure proper fit and clearance for insulation or multiple conduits.
Over-tightening the nuts, leading to distortion.Tighten nuts gradually and evenly. Torque specifications should be followed if available, or tighten until the pipe is secure without deforming the U-bolt or the pipe itself.
Using standard steel U-bolts in corrosive environments.For marine, chemical, or high-humidity applications, opt for corrosion-resistant materials like Aluminum 6061 to prevent premature failure and ensure system integrity.

Common Applications

  • Marine and offshore piping systems
  • Chemical processing plants
  • Water treatment facilities
  • Plumbing and HVAC installations
  • Conduit and cable support

⚠️ Engineering Warnings

  • Ensure proper torque is applied to avoid damaging the pipe or U-bolt.
  • Verify material compatibility with the surrounding environment to prevent galvanic corrosion if in contact with dissimilar metals.
