Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening nuts, deforming the pipe or support.Use a calibrated torque wrench and adhere to recommended torque specifications for the pipe and support material.
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) for proper fit.

Common Applications

  • Marine piping systems
  • Chemical processing plants
  • Water treatment facilities
  • Offshore oil and gas platforms

⚠️ Engineering Warnings

  • Ensure compatibility of brass with surrounding materials to prevent galvanic corrosion.
  • Regularly inspect for signs of wear, corrosion, or loosening, and re-tighten as necessary.
