Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always verify the nominal pipe size and cross-reference with the U-bolt's inside width (A) and length (B) to ensure a proper fit.
Over-tightening the U-bolt nuts, potentially deforming the pipe or the U-bolt.Consult torque charts for the specific thread size and material, and use a calibrated torque wrench for accurate tightening.
