Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or the U-bolt.Tighten nuts evenly to the manufacturer's recommended torque or until snug, allowing for slight flexibility without excessive stress.
Using the wrong size U-bolt for the pipe diameter, leading to a loose or over-constricted fit.Always verify the pipe's nominal size and select a U-bolt with the corresponding inside width and length specifications.

Common Applications

  • Pipe Hangers and Supports
  • Conduit and Cable Securing
  • Structural Steel Connections

⚠️ Engineering Warnings

  • Ensure compatibility of nuts and washers with the U-bolt thread size and material.
  • Consult engineering specifications for proper torque values to prevent over-stressing.
