Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an undersized or oversized U-bolt, leading to insecure or damaging pipe support.Verify pipe outer diameter and select a U-bolt with corresponding inside dimensions for a snug, effective fit.
Over-tightening the nuts, which can deform the pipe or the U-bolt threads.Tighten nuts until snug and secure, ensuring even pressure on both sides without excessive force.

Common Applications

  • Marine and offshore pipe support
  • Plumbing systems in corrosive environments
  • Chemical processing equipment mounting

⚠️ Engineering Warnings

  • Ensure the brass U-bolt is compatible with the fluid or environment it will be exposed to.
  • Do not exceed the recommended load capacity for the U-bolt and its mounting hardware.
