Installation Procedure

1. Position the U-bolt around the 3-inch pipe, ensuring it straddles the pipe and rests against the mounting surface. 2. Thread the 1/2"-13 nuts onto the U-bolt legs, snugging them against the mounting surface. 3. Tighten the nuts evenly and progressively to achieve the required clamping force, 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 damaging the U-bolt threads.Use a torque wrench to adhere to recommended torque specifications for the chosen nuts and washers, or tighten incrementally and evenly.
Using a U-bolt with incorrect dimensions for the pipe size, leading to a loose or insecure fit.Always verify the pipe's nominal size and compare it with the U-bolt's Inside Width (A) and Inside Length (B) before installation.

Common Applications

  • Marine and offshore structural support
  • Chemical processing plant pipe anchoring
  • Aerospace and aviation component fastening

⚠️ Engineering Warnings

  • Ensure compatibility with all mating hardware (nuts, washers) as these are not included.
