Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a U-bolt with incorrect dimensions for the pipe size.Always verify the U-bolt's inside width and length against the nominal pipe size and required clearance for a secure and effective fit.
Over-tightening or uneven tightening of the nuts, leading to pipe deformation or stress.Tighten nuts gradually and evenly, alternating between legs, to achieve firm support without deforming the pipe or creating excessive stress points.

Common Applications
