Installation Procedure

1. Position the U-bolt around the pipe, ensuring proper alignment with the mounting surface. 2. Thread the nuts onto the U-bolt legs, initially by hand to verify engagement and prevent cross-threading. 3. Tighten the nuts alternately and evenly using appropriate wrenches, gradually applying torque until the desired clamping force is achieved, ensuring the pipe is securely held without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, leading to pipe deformation or U-bolt fatigue.Apply torque gradually and alternately. Consult engineering specifications for recommended torque values if available for the specific application.
Using the wrong size U-bolt for the pipe, resulting in a loose or overly compressed fit.Verify the nominal pipe size and compare it to the U-bolt's internal dimensions (width and length) before installation.

Common Applications
