Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the U-bolt or damage the pipe.Tighten nuts until snug, then apply an additional 1/4 to 1/2 turn, ensuring even pressure on both sides. Use a torque wrench if precise tension is required.
Using the wrong size U-bolt for the pipe diameter, leading to a loose or damaged connection.Always verify the nominal pipe size and select the U-bolt with the corresponding inside width that accommodates the pipe's outer diameter.

Common Applications

  • Marine pipe and conduit support
