Installation Procedure

1. Position the U-bolt to straddle the 3" pipe, ensuring even contact with the pipe's outer surface. 2. Thread the provided nuts onto the U-bolt legs, tightening them progressively and alternately to apply uniform pressure. 3. Ensure the U-bolt is securely fastened, providing stable support without deforming the pipe or the U-bolt itself.

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 and progressively until snug, avoiding excessive force. Use a torque wrench if precise tension is required.
Using the wrong size U-bolt for the pipe, leading to a loose or insecure fit.Verify the pipe's nominal size and compare it with the U-bolt's inside dimensions (Width A and Length B) before installation.
Ignoring potential galvanic corrosion when used with dissimilar metals.While brass offers good resistance, ensure compatibility with surrounding materials, especially in highly corrosive environments. Consult material compatibility charts if unsure.

Common Applications

  • Marine pipe and conduit support
  • Chemical processing equipment plumbing
  • Water treatment system installations
  • Plumbing in corrosive environments

⚠️ Engineering Warnings

  • Ensure proper thread engagement to avoid stripping.
  • Use appropriate torque values to prevent over-stressing the material.
