Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the nuts, leading to pipe deformation or damage to the U-bolt threads.Use a torque wrench set to the manufacturer's recommended specification for the pipe size and U-bolt material.
Using the wrong size U-bolt for the pipe, resulting in a loose or insecure fit.Verify the nominal pipe size and consult the U-bolt's inside width (A) specification to ensure proper fit.

Common Applications

  • Marine and offshore piping systems
  • Chemical processing plant infrastructure
  • Water treatment facilities
  • Plumbing and HVAC systems in corrosive environments

⚠️ Engineering Warnings

  • Ensure compatibility of brass with surrounding materials to prevent galvanic corrosion.
  • Inspect regularly for signs of wear, damage, or corrosion, especially in harsh environments.
