Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe diameter.Always verify the pipe's nominal diameter and select a U-bolt with compatible inside dimensions for proper fit and load distribution.
Insufficient tightening of nuts, leading to pipe movement.Tighten nuts to the recommended torque specification, ensuring even pressure distribution to prevent vibration and slippage.
Using standard carbon steel hardware in corrosive environments.Always use 316 stainless steel nuts and washers with 316 stainless steel U-bolts to maintain corrosion resistance and prevent galvanic corrosion.
