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 select a U-bolt with an inside diameter that matches or slightly exceeds it to allow for insulation or coatings.
Over-tightening the nuts, potentially deforming the pipe or bracket.Tighten nuts gradually and evenly, ensuring the U-bolt provides firm support without excessive pressure that could damage the system.

Common Applications

  • Marine piping support
