Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an incorrect U-bolt size for the pipe diameter.Always verify the pipe's nominal size and select a U-bolt with appropriate inside dimensions (width and length) to ensure a proper fit.
Over-tightening or under-tightening the nuts.Consult engineering drawings or application guidelines for the correct torque specification to avoid damaging the pipe or mounting surface, or compromising the hold.

Common Applications

  • Marine piping systems
  • Chemical processing equipment
  • Plumbing and HVAC installations in corrosive environments

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or gas being transported in the pipe.
  • Always use appropriate safety equipment, including eye protection, when installing.
