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 compare it to the U-bolt's inside dimensions (A and B) to ensure a proper fit.
Over-tightening the nuts, which can deform the pipe or damage the threads.Tighten nuts incrementally and evenly. Consult pipe support standards for recommended torque values if available.
Using steel U-bolts in corrosive environments where brass is specified.Select brass U-bolts for environments prone to corrosion, such as saltwater or chemical exposure, to prevent premature failure.

Common Applications

  • Marine piping systems
