Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or U-bolt.Tighten nuts until snug, then apply an additional 1/4 to 1/2 turn, ensuring a firm but not excessive hold.
Using the wrong size U-bolt for the pipe diameter.Verify the nominal pipe size and U-bolt dimensions (inside width and length) to ensure a proper fit before installation.

Common Applications

  • Marine and offshore piping systems
  • Chemical processing equipment support
  • Plumbing and HVAC installations in corrosive environments

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the transported fluid and surrounding atmosphere to prevent galvanic corrosion.
  • Regularly inspect U-bolts for signs of wear, corrosion, or loosening, and re-tighten or replace as necessary.
