Installation Procedure

1. Position the U-bolt around the pipe, ensuring it sits flush against the mounting surface or support structure. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially to secure the pipe. 3. Use a calibrated torque wrench to tighten the nuts to the manufacturer's recommended torque specification, ensuring even pressure on both sides for optimal pipe support and vibration dampening.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt with an incorrect inside diameter for the pipe size, leading to loose support or pipe damage.Always verify the U-bolt's inside dimensions against the specific pipe's outside diameter and any insulation.
Over-tightening or under-tightening the U-bolt nuts, which can compromise pipe integrity or structural support.Employ a calibrated torque wrench and adhere to recommended torque values for secure and effective installation.

Common Applications
