Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe.Always verify the nominal pipe size and consult the U-bolt's internal dimensions (A and B) to ensure a proper fit.
Over-tightening or under-tightening the nuts.Use a torque wrench to apply the manufacturer's specified torque to ensure secure fastening without damaging the pipe or mounting surface.
Not using washers, leading to potential damage to the mounting surface.Always use appropriate washers between the nut and the mounting surface to distribute the load and prevent damage.

Common Applications

  • Pipe Support in Corrosive Environments
  • Marine and Offshore Structures
  • Chemical Processing Plants
  • Plumbing and HVAC Systems
  • Electrical Conduit Support

⚠️ Engineering Warnings

  • Ensure compatibility of brass with surrounding materials to prevent galvanic corrosion.
  • Do not exceed the maximum load rating of the U-bolt or its mounting system.
