Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it rests squarely on the pipe's exterior. 2. Place the accompanying U-bolt plate (if applicable) or flat washer against the pipe's curvature, on the opposite side of the U-bolt legs. 3. Thread the nuts onto the U-bolt legs, tightening them evenly and progressively to achieve the specified torque, ensuring the pipe is securely held without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening nuts, potentially deforming the pipe or U-bolt.Use a torque wrench to tighten nuts to the manufacturer's recommended specification for the pipe and U-bolt.
Using the wrong size U-bolt, leading to a loose or insecure fit.Verify the pipe's nominal size and the U-bolt's inside dimensions (width and length) before installation.

Common Applications

  • Pipe support and anchoring in marine environments
  • Securing conduits and tubing in chemical processing plants
  • Structural support in corrosive industrial settings

⚠️ Engineering Warnings

  • Ensure compatibility of thread pitch and diameter with appropriate fasteners.
  • Inspect U-bolt for any signs of damage or corrosion before installation.
