Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, leading to deformation of the pipe or U-bolt.Utilize a torque wrench to apply the manufacturer's recommended torque specification or consult engineering drawings for precise tightening values.
Using a U-bolt of incorrect dimensions for the pipe size or application.Verify the pipe's outer diameter and compare it against the U-bolt's inside dimensions (width and length) to ensure a proper fit and adequate support.

Common Applications

  • Pipe support and clamping in corrosive environments
  • Marine and offshore structural applications
  • Chemical plant piping systems
  • Industrial conduit and cable tray support

⚠️ Engineering Warnings

  • Ensure compatibility of nuts and washers with Aluminum 6061 to prevent galvanic corrosion.
  • Do not exceed the maximum load capacity as determined by engineering calculations.
