Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel U-bolt in a corrosive environment.Select a brass U-bolt for superior corrosion resistance in marine, chemical, or high-humidity applications.
Over-tightening the nuts, leading to pipe deformation.Tighten nuts to the recommended torque specification for the pipe and support system to prevent damage.
Incorrect U-bolt dimensions for the pipe size.Always verify the inside width (A) and inside length (B) of the U-bolt match the nominal pipe size and desired support configuration.

Common Applications

  • Marine pipe support
  • Chemical processing plant piping
  • Food and beverage industry installations
  • Plumbing in corrosive atmospheres
  • General industrial pipe securing

⚠️ Engineering Warnings

  • Ensure compatibility of brass with transported media if direct contact is expected.
  • Always use appropriate thread-locking compounds if vibration is a concern.
  • Do not exceed the rated load capacity of the U-bolt and its associated hardware.
