Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using an incorrect U-bolt size for the pipe diameter.Always verify the U-bolt's inside width and length against the nominal pipe size to ensure a secure and proper fit.
Over-tightening or under-tightening the nuts.Consult torque charts for the specific thread size and material to achieve optimal clamping force without deforming the pipe or hardware.

Common Applications

  • Marine and offshore pipe support
  • Chemical processing plant piping
  • Food and beverage industry conduit securing
