Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or U-bolt.Tighten nuts until snug, then apply an additional 1/4 to 1/2 turn. Use a torque wrench if precise specifications are required.
Using the wrong size U-bolt for the pipe diameter, leading to insecure fastening or damage.Always verify the pipe's nominal diameter and select a U-bolt with corresponding internal dimensions for optimal fit.
