Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel U-bolt in a highly corrosive environment.Always specify brass or other corrosion-resistant materials like stainless steel for environments prone to rust and chemical attack.
Incorrectly measuring pipe OD and selecting an undersized or oversized U-bolt.Verify the nominal pipe size and ensure the U-bolt's inside dimensions (width and length) are compatible with the pipe's outside diameter for optimal fit and support.

Common Applications

  • Marine pipe and conduit support
  • Chemical processing plant piping
  • Plumbing in corrosive atmospheric conditions
  • Industrial fluid transfer systems

⚠️ Engineering Warnings

  • Ensure compatibility of mounting surface material with brass to prevent galvanic corrosion.
  • Always use appropriately sized nuts and washers for secure and reliable fastening.
