Installation Procedure

1. Position the U-bolt around the pipe, ensuring it straddles the pipe's circumference. 2. Place the U-bolt's threaded legs through the designated mounting holes of the supporting structure or bracket. 3. Secure the U-bolt by threading nuts onto the exposed bolt legs, tightening them evenly until the pipe is firmly held without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the U-bolt nuts, leading to pipe deformation or premature failure.Tighten nuts to the manufacturer's recommended torque specification, ensuring a secure fit without excessive pressure on the pipe.
Using the wrong size U-bolt, resulting in a loose or insecure pipe support.Verify the nominal pipe size and select a U-bolt with the corresponding inside width specification for a precise fit.

Common Applications
