Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe.Always verify the nominal pipe size and consult the U-bolt's inside dimensions (Width 'A' and Length 'B') to ensure a proper fit.
Overtightening U-bolt nuts, deforming the pipe or U-bolt.Tighten nuts progressively and evenly. The goal is to secure the pipe without causing permanent deformation to either the pipe or the U-bolt.

Common Applications

  • Pipe and conduit support in corrosive environments
  • Marine applications
  • Chemical processing plants
  • Food and beverage industry infrastructure

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts, washers) with 304 stainless steel to prevent galvanic corrosion.
  • Do not exceed the rated load capacity of the U-bolt assembly.
