Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel U-bolt in a corrosive environment.Always select brass or other corrosion-resistant materials for environments prone to chemical exposure or high humidity to prevent premature failure.
Overtightening the U-bolt, leading to pipe deformation.Apply torque gradually and evenly, using a torque wrench if possible, to achieve a secure fit without crushing or damaging the pipe.
Incorrectly measuring pipe for U-bolt selection.Confirm the nominal pipe size (NPS) and measure the actual outer diameter of the pipe to ensure accurate U-bolt dimension selection.

Common Applications

  • Marine piping support
  • Chemical processing pipelines
  • Food and beverage industry systems
  • Plumbing in humid or corrosive environments

⚠️ Engineering Warnings

  • Ensure compatibility of brass with specific chemicals present in the application.
  • Do not exceed the recommended torque specifications to prevent damage to the pipe or fastener.
