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 consult the U-bolt's inside dimensions (A and B) to ensure a proper fit.
Over-tightening the nuts, which can deform the pipe or U-bolt.Apply torque evenly and avoid excessive force; use a torque wrench if specified for the application.
Using a U-bolt material not suitable for the environmental conditions.Select brass for its corrosion resistance in specific environments; consider galvanized steel or stainless steel for other applications.

Common Applications

  • Plumbing and Pipe Support
  • Marine and Offshore Installations
  • Chemical Processing Equipment
